“User App” is an application program running on MT3620, which uses AT-command at
chapter 3.2 to communicate with “gemtekMonitor”.
“gemtekMonitor” is a daemon running at MT7688, which handles AT commands from
MT3620, and gives responses respectively. Please refer to chapter 3.2 to see the
command details. When “gemtekMonitor” gets ready, it will send “+ROUTER_READY” to
MT3620.
