I have an interesting question.
We have developed program for q2501b, every minute module sends to server data via GPRS.
It is not good for us.
Maybe somebody knows some sollution-event to make module waiting for some command-event, ant then start sending data.
As i know it is possible to start send data when module gets a call or sms.
Call takes to long, sms costs too much. Need other alternative.
Have anybody some ideas how to send a request to module?
Thanks a lot
