ArduinoBleTransport.h

Go to the documentation of this file.

// Transport for the ArduinoBLE API: ArduinoBLE (Nano 33 BLE / IoT, UNO R4 WiFi, MKR WiFi 1010,
// Nano RP2040 Connect, Portenta, GIGA) and STM32duinoBLE (same API, different include).
// Notifications are flow-controlled by the library itself: BLECharacteristic::writeValue()
// blocks until the controller has a free buffer (HCI.cpp, sendAclPkt), so notify() never
// returns false here. Requires PhyphoxBLE::poll() in loop() (BLE.poll()).
