4.2.2.22. Accelerometer On/Off Query.
This command is intended to be used ONLY in units where the hardware has been configured to connect the accelerometer to
the Nordic processor. If a Motion Activated Track is running, that command will be NAK’d.
4.2.2.23. “Send Redundant Burst with GPS” command
This command is used to initiate a redundant burst message (as setup in STX configuration). Bytes 1 – 6 of the first packet of
the message shall contain latitude and longitude in standard Globalstar 24-bit format. Since each on-air message must be a
multiple of 9 bytes, the message will contain up to 16 9-byte packets depending on the size of the payload.
