nRF9160 - at_client freeze

Hi guys,

here in Croatia I'm trying to connect to NB-IOT network using nrf9160.

Here are the commands i am executing:

AT+CFUN?
AT+CFUN=1
AT+CGDCONT=1,"IP","iot.ht.hr"
AT+CFUN?
# i dont get any messages here only OK
AT+COPS=?

After this command modem does not accept any command.

I'm i missing something? Is there something i can try?

Thanks

  • I'm trying right now with v1.0.0 master but same results as colleague mentioned.

    However, he didn't say we are running nrf/samples/nrf9160/at_client using SES and using LTE Link Monitor from nRF Connect v3.2.0.

    We are using loacal NB1 network from hrvatski telekom (signal reception tested). APN was set with AT+CGDCONT=1,"IP","iot.ht.hr" before running AT+CFUN?.

    We are getting every status green except LTE which is switching between red and yellow (take a look at photo below), but we don't get connection even after half hour. It seems like device has no reception because +CESQ: 99,99,255,255,255,255.
