UI based test
- Target Board that wired 4lines(UART Tx/Rx lines, VCC, GND)
- Serial converter (USB to UART)
- Tester device (Spectrum analyzer or BLE RF Test equipment or nRF52 device)
- If you use the nRF5x development kit, recommend the nRF52833-DK which supports full features
- The BLE RF test equipment here used TC-3000C, MTP300A of TESCOM
- Download SDK (NCS or nRF5 SDK)
- Open the DTM example
- Change the UART lines for the target device (In the case of nRF5 devices, no need to change it)
- Build and Flash the firmware
- If you want to get the average RSSI value during the receiver test, you need to implement the relevant source code
-
Connect the UART wires between the Serial converter and the target device
-
Connect the serial converter to the PC
-
Open the nRF DTM tool
-
Select the COM port and the baud rate for the serial converter
- The default baudrate is 19200bps.
-
Configure the settings that you want to test (Transmitter/Receiver/Channel/Tx Power/Length/Model/Datarate/...)
-
To use Link-Layer Channels, you need to enable the
Link channel mode
-
-
Configure the run-time
-
Start the DTM test by clicking the START button
RECEIVER
- Connect the nRF5x development kit to a PC
- Open the nRF DTM tool that setting with Receiver mode
- Set the same channel and data rate that configured on the Transmitter
- Start the nRF DTM
RSSI Viewer
- Connect the nRF5x development kit(or Target device) to a PC
- Open the RSSI Viewer of nRF Connect for Desktop
- Select the connected DK (if you didn't flash the firmware for the RSSI viewer then it will ask you to flash the firmware)
- Start the RSSI viewer
Tester
- Connect the target device to the RF test instrument through an RF cable
- Connect serial lines through "USB to UART" device
- Configure the serial mode with 2-wire (or USB to 2-wire)
- Start test on the instrument
