Read / Write BLERemoteCharacteristic like stream or serial #626

Hello, i hope anyone can help me with my little problem.

i have a Bluetooth device that act like a serial interface, it wait for data like A503000.... and answer with similar over wire it works perfect, so it exist a Bluetooth dongle for this device that "replace" the wire and give me the serviceUUID: 0xfff0

so i have a library/function that build and send this data, and receive it and split it in readable pieces, badly the library need a stream class where it can send and receive.

any chance to build a function that create a stream class like a serial with read, write, flush, available... from the BLERemoteCharacteristic?

the BluetoothSerial library doesn't work, it cant discover or connect this Bluetooth device.

This would require skipping the GATT layer and going to l2cap. This is possible but probably not something many would be familiar with. When the PR at esp-nimble-cpp is ready I will look to add it here.
