Making a BLE singleton

[StngBo]

Apologies,

I found the solution here I think:

BleCharacteristic initialization in a class

The problem is that the BleCharacteristic callback is a BleOnDataReceivedCallback. Unlike some other classes, this unfortunately can’t take a C++ class instance directly so you need to implement it with two member functions, one static and one not. // In BLEHandler class definition void onDataReceived(const uint8_t* data, size_t len, const BlePeerDevice& peer); static void onDataReceivedStatic(const uint8_t* data, size_t len, const BlePeerDevice& peer, void* context); // Characteristic defnit…
