TX FIFO Buffer Handling

Starting with firmware version 0.6.7, when the TX FIFO buffer is full a 200ms blocking delay

will be used to see if any free space becomes available in the FIFO before returning ERROR.

The exact process is detailed in the flow chart below:

back-slash for the escape code to arrive as-intended in the AT command. For

example: ble.println("AT+BLEUARTTX=Some Test\\r\\n");

You must be connected to another device for this command to execute

# Send a string when connected to another device

AT+BLEUARTTX=THIS IS A TEST

# Send a string when not connected

AT+BLEUARTTX=THIS IS A TEST

ERROR
