Beacon Management Message Definitions
7.1.
System Messages
System messages are the core set of command supported by the beacon in both its normal
operating mode and in Bootloader mode.
These commands provide basic functions to determine if the device is response, identify its
hardware/firmware configuration, and allow firmware reprogramming.
7.1.1.
CID_SYS_ALIVE
The CID_SYS_ALIVE command is a simple command that can be periodically sent to the
beacon to determine if the hardware is present, connected and functioning.
For example, a host system sending the CID_SYS_ALIVE command at regular intervals can use
the response reply to reset a “connection lost” timeout timer, so that when a connection fails
the lack of responses can indicate to the user the hardware is no longer present.
