1.9.0

• Added Adafruit_ATParser helper class to facilitate sending and receiving AT commands:
  • .atcommand() : Send a command without reply (several variants defined for various input parameters)
  • .atcommandIntReply() : Send a command with integer reply (several variants defined for various input parameters)
  • .atcommand_full() : General purpose command execution with a pointer to the reply buffer
  • .printByteArray() : Outputs a byte array in the AA-BB-CC format from a buffer. Useful for executing AT commands.
  • .waitForOK() : Uses a separate temporary buffer to avoid overwriting response content.
• Callback support in Adafruit_BLE class
  • Supported Events are:
    • Connect: Set using setConnectCallback()
    • Disconnect: Set using setDisconnectCallback()
    • BLE UART RX: Set using .setBleUartRxCallback()
    • MIDI RX: Set using .setBleMidiRxCallback()
    • GATT Characteristic RX: Set using .setBleGattRxCallback()
  • .update(ms) must be placed in the loop() function to fire the callbacks, where ms is the interval in milliseconds to poll for new events
  • See 'examples/callbacks' for more details
• Added Adafruit_BLEGatt helper class to make working with custom GATT services and characteristics easier:
  • Helpers to add custom GATT services and characteristics
  • Helpers to read/write previously defined characteristics
  • Callback support for characteristic updates
  • Added User Description and Presentation Format support for GATT characteristics
  • Add BLEDataType_t typedef for GATT characteristics
  • See 'example/healththermometer' for an example of using the Adafruit_BLEGatt class
• Added BLE MIDI service support with the Adafruit_BLEMIDI class
  • See 'examples/midi' for details
• Added BLE Battery service support via the Adafruit_BLEBattery class
  • See 'example/battery' for more details
• Added BLE Eddystone helper class to facilitate using Eddystone beacon
  • See 'example/eddystone' for more details
• Add a 256 byte user NVM data section that can be accessed via .writeNVM() and .readNVM() in Adafruit_BLE. User can use this small chunk of NVM memory to store application specific data.
  • See 'example/nvmdata' for more details
• Additional Adafruit_BLE class changes:
  • Added a setAdvData() helper to advertise custom data payloads
