Hi Alex, sorry for the “radio silence”
Over the last week or so, we have been trying to reproduce the problem… out of about 12 Pis, of all different types, we could reproduce it on one. Right now, we are debugging the n_gsm kernel driver to see where it is failing.
Regarding the garbage characters..Does this happen if you do not use ttyGMS1 at all? E.g. use GMS2 for AT commands and GMS3 for steaming
