This version implement comprehensive LESC and Legacy pairing using dynamic & static Passkey.

  • Support static passkey (Legacy only)
  • Support LESC on nRF52840 using hardware-accelerated ARM CryptoCell CC310 provided by Adafruit_nRFCypto. The library is included as submodule and released together with the BSP.
  • Rework bonding mechanism to use IRK for peer finding. It is advisable to run clearbonds example to clean up bond files of previous version
  • Add setPins() to SPI class
  • Fix bug that with saving cccd data
  • Add more pinMode type: INPUT_SENSE_HIGH, INPUT_SENSE_LOW, OUTPUT_S0S1 etc ...
  • Optimize mutex usage in UART
  • Add analogReadVDD() function
  • Update itoa.c for compiling with c++17
  • Fix BLEBeacon endian for major and minor
  • Fix compiling with MIDI v5, adding stub for BLEMidi's beginTransmission() and endTransmission()
  • Update BSP core to work with Adafruit_TinyUSB_Arduino version 1.0.0

BLESecurity

A new class BLESecurity (access with Bluefruit.Security) is added to handle security and pairing.

  • setPIN() to set static passkey, this will force to use Legacy Pairing
  • setIOCaps() to congiure IO capacities
  • setMITM() to enable/disable Man in The Middle protection (passkey), it is auto-enabled when using passkey
  • setPairPasskeyCallback() to register callback for displaying pairing passkey to user
  • setPairCompleteCallback() to register callback for the result of pairing procedure (succeeded or failed)
  • setSecuredCallback() to register callback which invoked when connection is secured. This happens after he pairing procedure is complete, or we re-connect with preivously bonded peer device

Other Changes

BLECentral

  • will automatically use stored Long Term Key to secure connection if paired/bonded with device previously

Bluefruit

  • Bluefruit::requestPairing() is removed, please use the BLEConnection::requestPairing() instead
  • Bluefruit::connPaired() is removed, please use BLEConnection::secure() instead
  • Default Device name is USB_PRODUCT if available e.g CLUE, Circuit Playground Bluefruit, Feather nRF52840 Express etc ...
  • Rename function for consistency BLEPeriph's setSlaveLatency() to setConnSlaveLatency()

BLEService

  • Added setPermission()

BLEConnection

  • BLEConnection::requestPairing() is now non-blocking, it will return right after sending request to peer device. Previously it is blocked until the pairing process is complete.
  • Added BLEConnection::secured() to check if the connection is secured/encrypted
  • Added BLEConnection::bonded() to check if we store Longterm Key with current peer
  • Removed BLEConnection:paried(), user should either use secured() or bonded() depending on the context
  • If bonded, getPeerAddr() will return peer public address instead of random address.
  • Rename getConnSupervisionTimeout() to getSupervisionTimeout()

New Example Sketches

  • pairing_pin to use static PIN for peripheral role
  • pairing_passkey to use dyanmic Passkey for pairing. On Arcada compatible device such as CLUE or Circuit Playground Bluefruit, TFT display will also be used to display passkey.
  • cental_pairing similar to pairing_passkey but for nRF running central role
  • ancs_arcada for displaying ancs on arcada such CLUE and/or CPB.
  • arduino_science_journal add sketch to run with Arduino Science Journal
  • adv_AdafruitColor example to tie Arduino to CircuitPython BLE color
