Nice!

I took a look at "%XSYSTEMMODE" and it was set to CAT M1 %XSYSTEMMODE: 1,0,0,0. I switched it to NB1 with AT%XSYSTEMMODE=0,1,0,0 and it worked.

Thx!

Hi.

Can you send me the log from the Link Monitor?

Also, what is the output of "AT%XSYSTEMMODE?"?

Best regards, Didrik

Hi,

we are using SIM from local carrier (hrvatski telekom) using same APN as mentioned in post above and we can confirm it works (using other devices).

iBasis SIM card didn't work for us.

Can you confirm that you are trying to connect to the correct APN?

Are you using a SIM card from your local carrier or the iBasis SIM card that came with the DK?

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.

TAG: v1.0.0-rc1-342-g5ac4434

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

Hi.

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

Which modem firmware version are you using?

Best regards,

Didrik
