Topic: GSM shield stops working after a week (Read 952 times) previous topic - next topic

My GSM shield on a MEGA Arduino is supposed to run continously. But now the shield stops after a week or so. There does not seem be an exact count of seconds when it stops, but it just stops. It is a bit hard to test, because the system is not here. I send the code by email. There is quite a lot code the mage, but it should be full, and I am not declaring any new variables or objects, so it is hard to see what in the code would take a week to crash.

Now as a test, and to keep everything online, the system sends a SMS once a day. Othervise there is not much happening with shield.

Has any of you seen similar.

From the product description:
"ON/OFF Button - there is a button for turning ON and OFF of the module. It is possible to do the same directly from the Arduino board. The reset signal of the GSM module is connected to the Arduino. This feature can help to improve a reliability of the whole application."

Have you trie turning the module off until needed?

Perhaps I should try that, I have not really thought about that. A problem with that is that the user may want to send an SMS to the system, and it should have an (almost)immediate effect.

So far I have used only "gsm.TurnOn();". I have planned to use gsm.TurnOn(); or a relay to reset the module every now and then. But inserting a relay in the system is difficult. And I'd like to know a reason for this problem, or be pretty sure it works before I start.
