We are using the EM DEV KIT-6001173 with the EM8695
We are not getting any 5G connecting. I attach our log file of AT commands. This looks correct to me. Do you agree?
Later we will try 4G mode, and perhaps NRINFO/LTEINFO - do these do a cell search/sweep?
Grateful for any thoughts please.

At!lteinfo will not do cell search
Did you set correct APN in at+cgdcont?
Thank you for replying.
We believe the APN is set correctly, we use the string provided by the SIM provider. I assume there is no odd syntax requirements? “ABC123.etr”
What does lteinfo do? Is there a way for us to confirm if the modem can see any cells? We worry perhaps we have bad antenna connections or power connections
How about at+cops=? To scan network operator?
my test shows that even no SIM card inserted, there is still signal on RSRP, probably your log shows that there is something wrong in your antenna:
at+Cfun=1
OK

Thank you for looking at this; I had worried about the power and antennas. There is no documentation for the devkit.
Which antenna ports should we be using? We are using the paddle antennas are in the RF connectors marked “AUX” and “MAIN”.
it should be OK to connect both AUX and MAIN antenna
Indeed, we just had poor reception despite testing lots of locations. Thank you for all the help.
