AT+BLEUARTTXF

This is a convenience function the serves the same purpose as AT+BLEUARTTX, but data

is immediately sent in a single BLE packet ('F' for

force

packet). This command will accept a

maximum of 20 characters, which is the limit of what can be send in a single packet.

Parameters: See AT+BLEUARTTX

Output: See AT+BLEUARTTX

AT+BLEUARTRX

This command will dump the UART service's RX buffer to the display if any data has been

received from from the UART service while running in Command Mode. The data will be

removed from the buffer once it is displayed using this command.

Any characters left in the buffer when switching back to Data Mode will cause the buffered

characters to be displayed as soon as the mode switch is complete (within the limits of

available buffer space, which is 1024 bytes on current black 32KB SRAM devices, or 160

bytes for the blue first generation BLEFriend board based on 16KB SRAM parts).

Codebase Revision: 0.3.0

Parameters: None

Output: The RX buffer's content if any data is available, otherwise nothing.

TX FIFO size before sending data, which you can do using the AT+BLEUARTFIFO

command. If not enough space is available for the entire payload, add a SW delay

until enough space is available. Any single AT+BLEUARTTX command can fit into

the FIFO, but multiple large instances of this command may cause the FIFO to fill

up mid transfer.

You can also use the AT+BLEUARTFIFO=RX command to check if any incoming

data is available or not.
