Custom board with nRF9160 - +CEREG=5,4

[shak2300]

Hi I created a custom board with nRF9160SiP

I follow the same schematic og Thingy:91

I ran some tests with VNA to see if the antenna matching was correct, and I see that I have a VSWR of 2.5:1, so it should be fine.

The problem occurs when I run the following commands:

Now I have this



It seems like: 

• AT+CEREG? returns:
  +CEREG: 5,2,"0A2B","010C0102",7
  This means you are subscribed to level 5 notifications, and the current status is 2 (searching for operator).

  Then:
  
  

  • Later, you see:
    +CEREG: 2
+CEREG: 4
    This means the modem is first searching for an operator (2), then enters an unknown state (4), which typically means it is out of E-UTRAN coverage or cannot find a suitable network.

Hello, 

What SIM card are you testing with? Do you get the same results on the Thingy:91 or nRF9160DK when running the same SIM and code?

Kind regards,
Øyvind

Hi,

I'm using the same SIM of nRF9160DK the iBasis SIM.

With the nRF9160DK I have no issues.
