Short Message Query |
Returns the current terminal parameter. |
Short Message Timing |
Editing with Mobile Phone Sending terminal, the terminal receives information and will actively apply to the platform for school time. |
Anti-disassembly alarm |
Detection starts from dark to light to alarm the platform. (Controllable switch, open by default). |
Anti-counterfeiting base station |
The terminal detects the pseudo base station and refuses to connect to prevent detection. |
Data transmission instructions:
1. When the terminal is first powered on, the GPS module starts to search for the signal. In 4 minutes, the GPS module will be closed immediately and the dial-up will start. After the last 80 or D8 data is sent, it will sleep for 8 seconds. If it has not been positioned, the dial-up will start after 4 minutes.
2. RTC wake-up or light-sensitive wake-up, the waiting time of GPS module is up to 150 seconds, and if 150 seconds is not positioned, the data will be dialed immediately. Only the waiting time of 7-30 minutes in timing mode is 90 seconds.
Note: If the terminal is not positioned and the maximum GSV value is less than 25, the waiting time of GPS module is 70s. After 70s, turn off the GPS module and dial up.
3. The compulsory dormancy time of 7-30 minutes in the timing mode is 3 minutes, the terminal does not sleep for 1-6 minutes in the timing mode, and the compulsory dormancy time of other modes is 6 minutes.
Note: Only when the terminal is not on line will it be forced to sleep.
