Hi together!
We are working with the Quectel RG255C-GL RedCap 5G modem and have a problem with the activation of the PDP context. As a result, the modem is sending the wrong DNN to the 5G core network during the PDU establishment request procedure (CID 2 with DNN “ims” is used instead of CID 1 “internet”). We configured the modem using the following AT commands:
-
Firmware version:
$ AT+GMR
RG255CGLABR01A04M4G -
We added a PDP context with CID 1 as shown below:
$ AT+CGDCONT?
+CGDCONT: 1,“IP”,“internet”,“0.0.0.0”,0,0,0,0,“”,0
+CGDCONT: 2,“IPV4V6”,“ims”,“0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0”,0,0,0,0,“”,0
+CGDCONT: 3,“IPV4V6”,“sos”,“0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0”,0,0,0,1,“”,0 -
The CGACT command confirms us that the PDP context is available.
$ AT+CGACT?
+CGACT: 1,0
+CGACT: 2,0
+CGACT: 3,0 -
However, when trying to activate the PDP context, the modem returns an error:
$ AT+CGACT=1,1
+CME ERROR: 30
Is there anybody who can has the same problem? Or does anybody know a solution?
Note: The same procedure works for us using the Quectel RM520N-GL modem using the same SIM card. Also the PDP context activation works without problems.
