Device Management for Mbed OS

(This was previously called Simple Mbed Cloud Client.)

This provides a way to add device management capabilities to Mbed OS devices using the Arm Pelion Device Management IoT platform.

It:

Enables applications to connect and perform firmware updates in a few lines of code.
Runs separately from your main application; it does not take over your main loop.
Provides LWM2M resources, variables that sync automatically through Pelion Device Management.
Helps users avoid doing blocking network operations in interrupt contexts, by automatically defering actions to a separate thread.
Provides end-to-end Greentea tests for Pelion Device Management.

This library makes it trivial to expose sensors, actuators and other variables to a cloud service. For a complete Pelion Device Management Client API, please see our documentation.

Device management for your Mbed OS application

Not every device (microcontroller, module or board) is capable of running device management features. Although you can add or extend some hardware capabilities, such as connectivity, storage and TRNG, others are impossible or inconvenient to extend (for example, RAM or flash).

The minimum requirements to add device management feature to your application are:

RAM: 128K or more.
Flash: 512K or more.
Real Time Clock (RTC).
(Optional but recommended) True Random Number Generator (TRNG).
A storage device: SD card, SPI flash, QSPI flash or data flash.
IP connectivity: Ethernet, Wi-Fi, cellular, 6LoWPAN or Thread.

Additionally, we recommend the latest version of Mbed OS support the device and any additional complementary hardware components, or that they have support for the APIs provided in the latest releases of Mbed OS.

Useful references:

Check which Mbed OS platforms are supported in the Pelion Device Management quick start guide.
Check the storage options available.
Check the network options available.

Adding a device management feature to your application

Add this library to your Mbed OS project:
```
$ mbed add https://github.com/ARMmbed/simple-mbed-cloud-client
```
If you do not have an Mbed OS project to add, you can create one with mbed new <your_application_name> and then the mbed add step above.

Reference the library from the main.cpp file, and add network and storage drivers. Finally, initialize the SimpleMbedCloudClient library. This is the architecture of a device management application with Mbed OS:

#include "simple-mbed-cloud-client.h"
#include <Block device>
#include <Filesystem>
#include <Network>

int main() {

    /* Initialize connectivity */
    NetworkInterface *net = NetworkInterface::get_default_instance();
    net->connect();

    /* Initialize storage */
    BlockDevice *bd = BlockDevice::get_default_instance();
    <Filesystem> fs("fs", &bd);

    /* Initialize SimpleMbedCloudClient */
    SimpleMbedCloudClient client(net, &bd, &fs);
    client.init();

    /* Create resource */
    MbedCloudClientResource *variable;
    variable = client.create_resource("3201/0/5853", "variable");
    variable->set_value("assign new value");
    variable->methods(M2MMethod::GET | M2MMethod::PUT);

}

Configure the API key for your Pelion Portal account.

If you don't have an API key available, then log in to the Pelion IoT Platform portal, navigate to Access Management and API keys, and create a new one. Then specify the API key as the global mbed configuration:
```
$ mbed config -G CLOUD_SDK_API_KEY <your-api-key>
```

Install the device management certificate:

$ mbed dm init -d "<your company name.com>" --model-name "<product model identifier>"

This creates your private and public key pair and also initialize various .c files with these credentials, so you can use Connect and (firmware) Update device management features.

Example applications

To help you start quickly, please refer to the following application example. It demonstrates how to connect to the Pelion IoT Platform service, register resources and get ready to receive a firmware update.

Also, there are a number of board-specific applications that focus on providing more elaborate hardware features with Mbed OS and the Pelion IoT Platform. These are available in the Pelion quick start. Please see the reference table below, organized by vendor name, for details:

Device management configuration

The device management configuration has five distinct areas:

Connectivity - the transport type for the device to connect to the device management service.
Storage - the storage type and writing used for both the credentials and the firmware storage.
Flash geometry - the device flash "sandbox" for bootloader, application header, application image and two SOTP regions.
SOTP - the address and size of the SOTP regions in flash used to store the device special key that decrypts the credentials storage.
Bootloader - the bootloader image, application and header offset.

Except for connectivity, the majority of the configuration is shared between the application and bootloader, which ensures the bootloader can correctly find, verify, authorize and apply an update to the device application.

For full documentation about bootloaders and firmware update, please read the following documents:

To hasten this process, you can copy the configuration from the application example as the basis for your application configuration.

1. Application configuration

Edit the mbed_app.json file, and create a new entry under target_overrides with the target name for your device:

Connectivity - Specify the default connectivity type for your target. It's essential with targets that lack default connectivity set in targets.json or for targets that support multiple connectivity options. For example:
```
         "target.network-default-interface-type" : "ETHERNET",
```
The possible options are ETHERNET, WIFI and CELLULAR.

Depending on connectivity type, you might have to specify more config options. For an example, please see the defined CELLULAR targets in mbed_app.json.
Storage - Specify the storage block device type, which dynamically adds the block device driver you specified at compile time. For example:
```
         "target.components_add" : ["SD"],
```
Valid options are SD, SPIF, QSPIF and FLASHIAP (not recommended). For more available options, please see the block device components.

You also have to specify block device pin configuration, which may vary from one block device type to another. Here's an example for SD:
```
         "sd.SPI_MOSI"                      : "PE_6",
         "sd.SPI_MISO"                      : "PE_5",
         "sd.SPI_CLK"                       : "PE_2",
         "sd.SPI_CS"                        : "PE_4",
```
If you are using SPI/QSPI flash, please make sure you have specified the correct SPI frequency by configuring spif-driver.SPI_FREQ. If it is not configured, 40Mhz will be applied by default.

Flash - Define the basics for the microcontroller flash. For example:

         "device-management.flash-start-address"              : "0x08000000",
         "device-management.flash-size"                       : "(2048*1024)",

SOTP - Define two SOTP or NVStore regions that Mbed OS Device Management will use to store its special keys, which encrypt the data stored. Use the last two Flash sectors (if possible) to ensure that they don't get overwritten when new firmware is applied. For example:

         "device-management.sotp-section-1-address"            : "(MBED_CONF_APP_FLASH_START_ADDRESS + MBED_CONF_APP_FLASH_SIZE - 2*(128*1024))",
         "device-management.sotp-section-1-size"               : "(128*1024)",
         "device-management.sotp-section-2-address"            : "(MBED_CONF_APP_FLASH_START_ADDRESS + MBED_CONF_APP_FLASH_SIZE - 1*(128*1024))",
         "device-management.sotp-section-2-size"               : "(128*1024)",
         "device-management.sotp-num-sections" : 2

*-address defines the start of the Flash sector, and *-size defines the actual sector size. sotp-num-sections should always be set to 2.

At this point, we recommend you run the "connect" test suite, which verifies that the device can successfully bootstrap, register and send and receive data from Pelion Device Management service with the provided configuration.

If you already configured your Pelion API key and initialized your credentials as described in the previous section, you can compile the "Connect" tests using:

$ mbed test -t <TOOLCHAIN> -m <BOARD> -n simple-mbed-cloud-client-tests* -DMBED_TEST_MODE --compile

To run the tests:

$ mbed test -t <TOOLCHAIN> -m <BOARD> -n simple-mbed-cloud-client-tests* --run -v

2. Bootloader configuration

After you've successfully passed the "Connect" tests as described above, you can enable firmware update feature by adding a bootloader to your application.

Import as a new application the official mbed-bootloader repository or the mbed-bootloader-extended repository that builds on top of mbed-bootloader and extends the support for file systems and storage drivers. You can do this with mbed import mbed-bootloader-extended.
Inside the imported bootloader application, and edit the application configuration, for example mbed-bootloader-extended/mbed_app.json. Add a new target entry similar to the step above, and specify:
- Flash - Define the basics for the microcontroller flash (the same as in mbed_app.json). For example:
```
      "flash-start-address"              : "0x08000000",
      "flash-size"                       : "(2048*1024)",
```
- SOTP - Similar to the SOTP step above, specify the location of the SOTP key storage. In the bootloader, the variables are named differently. Try to use the last two Flash sectors (if possible) to ensure that they don't get overwritten when new firmware is applied. For example:
```
        "nvstore.area_1_address"           : "(MBED_CONF_APP_FLASH_START_ADDRESS + MBED_CONF_APP_FLASH_SIZE - 2*(128*1024))",
        "nvstore.area_1_size"              : "(128*1024)",
        "nvstore.area_2_address"           : "(MBED_CONF_APP_FLASH_START_ADDRESS + MBED_CONF_APP_FLASH_SIZE - 1*(128*1024))", "nvstore.area_2_size" : "(128*1024)",
```
- Application offset - Specify start address for the application, and also the update-client meta information. As these are automatically calculated, you can copy the ones below:
```
        "update-client.application-details": "(MBED_CONF_APP_FLASH_START_ADDRESS + 64*1024)",
        "application-start-address"        : "(MBED_CONF_APP_FLASH_START_ADDRESS + 65*1024)",
        "max-application-size"             : "DEFAULT_MAX_APPLICATION_SIZE",
```
- Storage - Specify the block device pin configuration, exactly as you defined it in the mbed_app.json file. For example:
```
        "target.components_add"            : ["SD"],
        "sd.SPI_MOSI"                      : "PE_6",
        "sd.SPI_MISO"                      : "PE_5",
        "sd.SPI_CLK"                       : "PE_2",
        "sd.SPI_CS"                        : "PE_4"
```
If you are using SPI/QSPI flash, please make sure you have specified the correct SPI frequency by configuring spif-driver.SPI_FREQ. If it is not configured, 40Mhz will be applied by default.

Compile the bootloader using the bootloader_app.json configuration you just edited:

$ mbed compile -t <TOOLCHAIN> -m <TARGET> --profile=tiny.json --app-config=<path to pelion-enablement/bootloader/bootloader_app.json>

Note: mbed-bootloader is primarily optimized for GCC_ARM, so you may want to compile it with that toolchain. Before jumping to the next step, you should compile and flash the bootloader and then connect over the virtual comport to ensure the bootloader is running correctly. You can ignore errors related to checksum verification or falure to jump to application - these are expected at this stage.

3. Add the bootloader to your application

Copy the compiled bootloader from mbed-bootloader-extended/BUILDS/<TARGET>/<TOOLCHAIN>-TINY/mbed-bootloader.bin to <your_application_name>/bootloader/mbed-bootloader-<TARGET>.bin.
Edit <your_application_name>/mbed_app.json, and modify the target entry to include:
```
         "target.features_add"              : ["BOOTLOADER"],
         "target.bootloader_img"            : "bootloader/mbed-bootloader-<TARGET>.bin",
         "target.app_offset"                : "0x10400",
         "target.header_offset"             : "0x10000",
         "update-client.application-details": "(MBED_CONF_APP_FLASH_START_ADDRESS + 64*1024)",
```
Note:
- update-client.application-details should be identical in both bootloader_app.json and mbed_app.json.
- target.app_offset is relative offset to flash-start-address you specified in mbed_app.json and bootloader_app.json, and is the hex value of the offset specified by application-start-address in bootloader_app.json. For example, (MBED_CONF_APP_FLASH_START_ADDRESS+65*1024) dec equals 0x10400 hex.
- target.header_offset is also relative offset to the flash-start-address you specified in the bootloader_app.json, and is the hex value of the offset specified by update-client.application-details. For example, (MBED_CONF_APP_FLASH_START_ADDRESS+64*1024) dec equals 0x10000 hex.

Finally, compile and rerun all tests, including the firmware update ones with:

$ mbed test -t <TOOLCHAIN> -m <BOARD> -n simple-mbed-cloud-client-tests-* -DMBED_TEST_MODE --compile

$ mbed test -t <TOOLCHAIN> -m <BOARD> -n simple-mbed-cloud-client-tests-* --run -v

Refer to the next section about what tests are being executed.

Validation and testing

Mbed Device Management provides built-in tests to help you when define your device management configuration. Before running these tests, we recommend you refer to the testing setup section below.

Requirements

Mbed Device Management tests rely on the Python SDK to test the end-to-end solution. To install the Python SDK:

 $ pip install mbed-cloud-sdk>=2.0.6

Note: The Python SDK requires Python 2.7.10+ or Python 3.4.3+, built with SSL support.

Testing setup

Import an example application for Pelion Device Management that contains the corresponding configuration for your target.

Please refer to the following application example. It demonstrates how to connect to the Pelion IoT Platform service, register resources and get ready to receive a firmware update.

Also, there are board-specific applications that focus on providing more elaborate hardware features with Mbed OS and the Pelion IoT Platform. These are available in the Pelion quick start.
Set a global mbed config variable CLOUD_SDK_API_KEY on the host machine valid for the account your device will connect to. For example:
```
$ mbed config -G CLOUD_SDK_API_KEY <API_KEY>
```
For instructions on how to generate an API key, please see the documentation.
Initialize your Pelion DM credentials (once per project):
```
$ mbed dm init -d "<your company name.com>" --model-name "<product model identifier>"
```
This creates your private and public key pair and also initializes various .c files with these credentials, so you can use Connect and (firmware) Update device management features.
Remove the main.cpp application from the project, or ensure the content of the file is wrapped with #ifndef MBED_TEST_MODE.

Compile the tests with the MBED_TEST_MODE compilation flag.

$ mbed test -t <toolchain> -m <platform> -n simple-mbed-cloud-client-tests-* -DMBED_TEST_MODE --compile

Run the tests from the application directory:

$ mbed test -t <toolchain> -m <platform> -n simple-mbed-cloud-client-tests-* --run -v

Troubleshooting

Below are common issues and fixes.

Autoformatting failed with error -5005

This is due to an issue with the storage block device. If using an SD card, ensure that the SD card is seated properly.

Storage initialization failed with error -4002

This is observed when the device is using legacy serial flash which does not support SFDP, or the SPI frequency is not configured properly.

SYNC_FAILED during testing

Occasionally, if the test failed during a previous attempt, the SMCC Greentea tests fail to sync. If this is the case, please replug your device to the host PC. Additionally, you may need to update your DAPLink or ST-Link interface firmware.

If the test fails with SYNC_FAILED all the time, please check if the UART flow control pins (UART_CTS, UART_RTS) are properly defined. If your device supports flow control over UART, fill them with the corresponding pins; if not, please specify NC.

Device identity is inconsistent

If your device ID in Pelion Device Management is inconsistent over a device reset, it could be because it is failing to open the credentials on the storage held in the Enhanced Secure File System. Typically, this is because the device cannot access the Root of Trust stored in SOTP.

One way to verify this is to see if the storage is reformatted after a device reset when format-storage-layer-on-error is set to 1 in mbed_app.json. It would appear on the serial terminal output from the device as:

[SMCC] Initializing storage.
[SMCC] Autoformatting the storage.
[SMCC] Reset storage to an empty state.
[SMCC] Starting developer flow

When this occurs, look at the SOTP sectors defined in mbed_app.json:

"sotp-section-1-address"           : "0xFE000",
"sotp-section-1-size"              : "0x1000",
"sotp-section-2-address"           : "0xFF000",
"sotp-section-2-size"              : "0x1000",

Ensure that the sectors are correct according to the flash layout of your device, and they are not being overwritten during the programming of the device. ST-Link devices overwrite these sectors when you use drag-and-drop of .bin files. Thus, moving the SOTP sectors to the end sectors of flash ensures they are not overwritten.

Stack overflow

If you receive a stack overflow error, increase the Mbed OS main stack size to at least 6000. You can do this by modifying the following parameter in mbed_app.json:

 "MBED_CONF_APP_MAIN_STACK_SIZE=6000",

Device failed to register

Check the device allocation on your Pelion account to see if you are allowed additional devices to connect. You can delete development devices. After being deleted, they will not count toward your allocation.

In network test cases, tests over larger buffers passed, but tests over small buffers keeps failing

This could be observed with cellular modems driven by AT commands. Suggestions:

Connect the modem to an serial interface which supports hardware flow control, and define MDMRTS and MDMCTS correspondingly.
Use the highest possible baud-rate of your modem, e.g. 115200bps
For the UART connected to your host PC, choose one which supports hardware flow control
Set the STDIO UART baud-rate to 230400bps by configuring platform.stdio-baud-rate.

With SPI/QSPI Flash, LittleFS got corrupted after firmware update test

If you observe logs such as mbed assertation failed: block < lfs->cfg->block_count or invalid superblock, etc., please check if partition mode is set to 0:

"device-management.partition_mode"         : 0

Notification channel failures during LwM2M Resource test cases

This could be observed if a previously registered long-poll or webhook notification channel with the same API key existed. You may either use another API key, or delete the notification channel with curl command:

to delete Long Poll:

curl -H "Authorization: Bearer ${API_KEY}" -X DELETE ${API_URL}/v2/notification/pull

to delete WebHook:

curl -H "Authorization: Bearer ${API_KEY}" -X DELETE ${API_URL}/v2/notification/callback

Please note that long-polling is now deprecated and will be likely be replace in the future. Use callback notification channel (WebHook) instead.

I had built the test suites but somehow I got my Python environment messed up; can I run the test binaries without GreenTea?

The test binaries are built under:

  <repo folder>/BUILD/tests/<Target Name>/<Toolchain>/simple-mbed-cloud-client/TESTS/<Test Suites>/<test case>/<test case name>.hex.

You may copy the binary you want to manually test and flash it to the device, then when the device boots, paste the following line to the serial console to trigger the test:

 {{__sync;1}}

Device management for your Mbed OS application

Adding a device management feature to your application

Example applications

Device management configuration

1. Application configuration

2. Bootloader configuration

3. Add the bootloader to your application

Validation and testing

Test suites

Test cases - connect

Test cases - update

Requirements

Testing setup

Troubleshooting

Autoformatting failed with error -5005

Storage initialization failed with error -4002

SYNC_FAILED during testing

Device identity is inconsistent

Stack overflow

Device failed to register

In network test cases, tests over larger buffers passed, but tests over small buffers keeps failing

With SPI/QSPI Flash, LittleFS got corrupted after firmware update test

Notification channel failures during LwM2M Resource test cases

I had built the test suites but somehow I got my Python environment messed up; can I run the test binaries without GreenTea?
