PLS8 US version AT+COPS=0 not working | Telit Cinterion IoT Developer Community
March 5, 2019 - 4:28am, 1192 views
I have URCs enabled.
AT+COPS=0 always initially connects, then soon gets back to 2. But if I check for AT+COPS=? networks manually, then use AT+COPS=1 it works normally. Actually I am using the internet provieded by that modem right now, after a full day of trying to make it work through AT+COPS=0.
Some additional info:
- using Mint Mobile SIM cards (tested 2)
- AT+COPS=? returns a few RATs. AT+COPS=0 sometimes switches between 2 and 7, then it deregisters and AT+CREG returns 2 again. When I connect manually, RAT 7 does not work, but RAT 2 always does.
This behavior is consistant now for almost 6 months of testing. AT+COPS=0 randomly worked through 1 full day a few days ago. But all the rest of the days in 6 months I had to use manual register (AT+COPS=1)
Help from Gemalto would be really appreciated. Thak you
Hello,
So the module registers and then looses the registration. Could you specify how soon it happens? Is the device moving? Have you also been verifying the network quality parameters (for example AT+CSQ, AT^SMONI commands)? Please compare these outputs for manual and automatic registration. Is the antenna connected?
Does the module register automatically to the same network that you force manually? Can it register automatically to LTE?
Please paste ATI1, AT^SCFG?, AT+COPS=?, AT+CGDCONT?, AT+CGATT?, AT+CGACT? outputs.
Please also send AT+CEER after the module has lost the network.
Best regards,
