GPy, G01 #349

Open PiotrSrebrny opened 4 years ago

PiotrSrebrny commented 4 years ago

I am working with G01 and GPy LTE modem. I am trying to attach to the network however the procedure does not complete with lte.isattached == true. I am using Sequans firmware NB1-41019.dup and Pycom MicroPython 1.20.1.r1 [v1.11-3138a13] on 2019-10-08; GPy with ESP32 Pybytes Version: 1.1.3.

The steps I take are following:

from network import LTE lte=LTE() lte.attach(band=20, apn="xxx") lte.send_at_cmd("AT+CEREG?") '\r\n+CEREG: 3,2\r\n\r\nOK\r\n' # looking for network lte.isattached() False lte.send_at_cmd("AT+CEREG?") '\r\n+CEREG: 3,1,"9FC5","011FCC67",9\r\n\r\nOK\r\n' lte.isattached() False

lte.isattached() always indicates that it is not attached.

Which firmware version are you using?

robert-hh commented 4 years ago

Looking into the code, it seems to look for '+CEREG: 2,1,' and '+CEREG: 2,5,' but not for '+CEREG: 3,1,', so it misses the confirmation. So the question is, why your card responds with +CEREG: 3,1

Thank you for the answer. Now, I could fix my problem. I set the CEREG value manually via send_at_cmd() to 3 to get more verbose output when registering. This is way it appears in the response. I think that you can safely ignore the first number from CEREG response, as it is not relevant in order to determine attachment state.
