Legacy Legacy AirPrime modules

Hi everybody!

I have such problem on 5% of all Q2686.

After working for some time modem doesn’t answer on AT commands. If a use RESET pin, the module doesn’t resets, only after POWER OFF/ON the module is back to life.
So it seems that it is hardware modems problem because RESET pin has to reset microprocessor in any way!!! :open_mouth:

Has someone such problems?
