0.22.0 - 2021.05.23

All credits for this update go to the Adafruit team
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

Minor Update

• Make BSP compatible with the new SX126x-Arduino V2.0.0 library
• Update LoRa/LoRaWAN examples for the new SX126x-Arduino V2.0.0 library
• Add new WisBlock module examples
