If I intend to use only one phone (always same IMSI) on only one specific BTS I would be able to calculate the timeslot, in this case is it possible to have the value of the timeslot hardcoded as a start for testing since I’m still new to osmocombb and must read a lot of code before being able to adjust it for my needs.
