+CLCC gives ERROR

Hi,

It is a little hard to characterise further. I use a pool of devices which continuously make calls, SMS, USSD and data sessions. I can’t find a common scenario causing them to fail. The devices just seem to stop responding, usually after some hours or days.

I have two further questions:

  1. is there any way to “escape” or reset a sleeping device? I tried “+++” etc… but get nothing.
  2. is there any reset that I can do regularly to circumvent the occurrence? I don’t want to do complete reset as it takes too long. I was just thinking that the problem seems to occur after continuous use and maybe there is some kind of counter or memory leak?

regards
