There are three modes for A-GPRS1090I:“Always online”, “Offline when idle”, “Power down when idle”.

 Always online: It will connect to the preconfigured server when power on the module. And it will be kept

online all the time so the data can be transmitted at any time.

 Offline when idle: It will connect to the preconfigured server when power on the module. The module

will disconnect and turns to the sleeping mode if there isn’t any data in a period of time. There are three

methods to enable re-establish connection between the module and the server.

1. Send data to the serial port of the module, the module will connect to the server and then send the

out. .

2. Telephone wake-up: call the SIM card number, hang up after it rings for two times, the module will

re-establish a connection with the server

3. SMS wake-up: set one of the SMS certification users to the SIM card number in the Configuration

Tool. The format of the number is “+861**********”. (for China’s SIM card, it is 86) Send the SMS

“888888: Wakeup”. It will return “OK” which means the module has re-connected to the serve.

 Power down when idle: after the module disconnecting the connection with the server, the module will cut

off the power of GPRS module, and make the system into power-down status to achieve low power

consumption

There is only one method to wake up the module: send data to the serial port of the module, the module will

connect to the server after the data is sent successfully.
