Post subject:  Problems communicating with waspmote 3G Module

We build a data logger with waspmote + SIM5215E 3G module. The logger worked fine but then stopped sending data some day.

On site with the USB cable attached we got the message

[PWR] Noise in Interruption line

just before the program entered the deepSleep.

When waking up again the waspmote was not able to activate the 3G Module with _3G.ON()
This stopped the data transmission apparantly. The rest of the code worked fine.

We have attached the battery, solar module and one single analog sensor on Gnd, 3V3 SENSOR and Analog 6 on the small 6x2Pin Connector.

We couldn't solve the issue by pressing the reset button. Switching the on/off switch and waiting a bit enabled data transmission again though. With this also the message about the noise in the interrupt line disappeared.

Is there static building up that causes this noise and makes the communication to the 3G module impossible? Can we take any counter measures to prevent that?

Thank you very much for some help!
