4.14. Non Movement Detection
In order to saving the power, when the device is standstill in one place, there is no need to send the
same redundant locations to the backend server many times. So the backend server could use the
command AT+GTNMD to make the device suspend its fixed timing report and geo-fence
checking when the device is detected to be at rest by the motion sensor. When the device moves
again, it will automatically resume the suspended function.
According to the setting, the device may send +RESP:GTNMR message to the backend server
when rest is detected.
Example 1:
To suspend the fixed timing report and geo-fence checking without sending the +RESP:GTNMR
message:
AT+GTNMD=gt300,1,4,1,2,0800,2000,0,,,,,000B
Example 2:
To send only the +RESP:GTNMR message:
AT+GTNMD=gt300,2,4,1,2,0800,2000,0,,,,,000B
The response message when the device is detected to be at rest:
+RESP:GTNMR,135790246811220,1,0,0,1,4.3,92,70.0,1,121.354335,31.222073,2009010100000
0,0460,0000,18d8,6141,00,11F0,0102070202
Example 3:
To both suspend the related report and send the +RESP:GTNMR message:
AT+GTNMD=gt300,3,4,1,2,0800,2000,0,,,,,000B
