nRF9160 - at_client freeze

[schef]

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

Hi.

Which tag are you on, e.g. master, v1.0.0?

Which modem firmware version are you using?

Best regards,

Didrik

Hello,

TAG: v1.0.0-rc1-342-g5ac4434

FW: AT+CGMM - nRF9160-SICA

AT+CGMR - mfw_nrf9160_1.0.1

Hopefully this is helpful. I made now checkout to v1.0.0 and will try again tomorrow.

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.
