Is there any BLE/Bluetooth connection available for Firmata connection?

[samchoy88]

Microbit built in with bluetooth/BLE connectivity. Is that possible using wireless channel to replace the USB serial port?

We did implement a serial profile for micro:bit v1, yes. I presume this was ported over along with the other services for v2. If not, it's probably not a difficult job....

I think this question might be more about being able to connect to a firmata client via BLE? Independently of the micro:bit board?

This library at the moment has only been tested on a serial connection, but I think the transport could be changed in these functions to send and receive data via other transports like Bluetooth:

microbit-firmata/firmware/source/mbFirmata.cpp

Lines 85 to 106 in fd57211

	static void receiveData() {
	while (inbufCount < IN_BUF_SIZE) {
	int byte = serial.read(ASYNC);
	if (byte < 0) return;
	inbuf[inbufCount++] = byte;
	}
	}
	static void sendByte(uint8_t b) {
	serial.sendChar(b, ASYNC);
	}
	static void send2Bytes(uint8_t b1, uint8_t b2) {
	serial.sendChar(b1, ASYNC);
	serial.sendChar(b2, ASYNC);
	}
	static void send3Bytes(uint8_t b1, uint8_t b2, uint8_t b3) {
	serial.sendChar(b1, ASYNC);
	serial.sendChar(b2, ASYNC);
	serial.sendChar(b3, ASYNC);
	}
