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