AT+BLEUARTFIFO

This command will return the free space available in the BLE UART TX and RX FIFOs. If you

are transmitting large chunks of data, you may want to check if you have enough free space

in the TX FIFO before sending, keeping in mind that individual GATT packets can contain up

to 20 user bytes each.

Codebase Revision: 0.6.7

Parameters: Running this command with no parameters will return two comma-separated

values indicating the free space in the TX buffer, following by the RX buffer. To request a

specific buffer, you can execute the command with either a "TX" or "RX" value (For example:

"AT+BLEUARTFIFO=TX").

Output: The free space remaining in the TX and RX FIFO buffer if no parameter is present,

otherwise the free space remaining in the specified FIFO buffer.
