Thank you for your quick answer! I think that I slowly get an idea how this works. So if I place the three pause stings from charging to the SMS pattern like this: PatternCommunicationSMS= 30;1;0;b;9d804000 02ff 03ff 02ff 03ff 7f00 7f00 4200 0000 ;9d80 0000 would that work? I don't want to brick my sweet N900 in the first week so I better ask two times
