  • Added setRssiCallback(), monitorRssi(), getRssi(), stopRssi() for tracking rssi of a connection. rssi_poll and rssi_callback are added as example sketches
• Remove BLEGap, API functions are taken by Bluefruit, BLEPeriph, BLECentral, BLEConnection
  • Gap.setAddr()/getAddr() are replaced by Bluefruit.setAddr()/getAddr()
  • Gap.requestPairing() is replaced by Bluefruit.requestPairing(), conn_handle parameter is also added
  • Most of other functions of BLEGap are replaced by BLEConnection's one
• BLECharacteristic
  • Change callback signature's parameter from BLECharacteristic& to BLECharacteristic*
  • conn_handle is added to all callbacks to support multiple peripheral's link
  • Use AdaCallback thread for BLECharacteristic callbacks
  • Support LONG WRITE a.k.a send more than MTU ( default = 20 bytes) per request. This fixed issue #91, #220
  • Fixed read32(), thanks @techno
  • Removed offset parameter in write callback signature
• BLEUart
  • Added conn_handle to API and callbacks
  • Removed auto flush TXD() with timer, user must call flushTXD() should bufferTXD() is enabled.
