4.2.2.28 "Suspend/Unsuspend" command
The purpose of this command is to suspend tracking due to battery low, as well as to suspend tracking when the unit is
in the "waiting to activate" state. If this command is issued with an argument for "full suspend" when the unit is not in
track, and then a "proprietary track" command is issued while in that suspended state, this condition shall be defined as
"waiting to activate" state, and the unit will begin tracking when this command is received with the "unsuspend" or
"partial suspend" argument.
The Nordic processor uses this command to transition from "battery very low", "battery low" and "battery OK" states.
