no signal

[a3p]

Hi,

i'm not getting any signal with a fresh DK and the latest modem driver.

AT+CESQ
+CESQ: 99,99,255,255,255,255
OK

entering AT+COPS=?  will make it unresponsive forever. (nordic LTE Link monitor times out, and no AT commands are possible before hard reset).

does not matter which simcard i use. The one i'm testing right now from telekom works just fine in a simcom lte-m modem.

unfortunately the devzone has no way to attach files, so i uploaded the trace file here:

Are you sure you have entered that command correctly?

According to the latest AT Manual, the command for reading the current selection mode and network is AT+COPS?, not =?

[a3p]

yes.

AT+COPS? is the current network, which is of course empty for me

AT+COPS?

+COPS: 0

hence AT+COPS=? to search for networks
