Firmware Version 2.22 through 2.30
Firmware version 2.22 through 2.30 supports a comma-delimited scan output format, which a microprocessor can use to
parse the RSSI information. The scan command output format is:

10.8 UART Heartbeat Messages
In firmware version 2.22 and higher, the module can output UART heartbeat messages. The bit-mapped message is output
periodically while the module is in data mode and not connected to a remote host. Messages are not output while in
command mode. The heartbeat message encodes the module’s state for the embedded microprocessor. Based on the
heartbeat message, the microprocessor can choose to change the configuration by going into command mode.
To enable the UART heartbeat messages, use the
set sys printlvl 0x10
command. The output of this mode is:
*8b30*8b30*8b30….
