RM520N - PDU_session_incl in resgistration request is set to 0

Hi,

We are testing with this communication module but we can see that the PDU context is not active inmediately, we need to set it by AT+CGACT=1. Could be the problem? How we can set this parameter to always get PDU context?

We are investigating about, but we can see the AT+CGDCONT configuration type with error in the result:

<Always-on_req> Integer type. Indicate whether the UE requests to establish the PDU session
as an always-on PDU session, see 3GPP TS 24.501.

at+cgdcont=1,“IP”,“thethinx.ndac.com”,“0.0.0.0”,0,0,0,0,“”,1
+CME ERROR: operation not supported

Could be the problem?

Dear @shenares
PDP context need to active via AT command.
The format of AT+CGDCONT you used is wrong, so it reponsed error.

Dear @shenares
Sorry, it can’t active by default in 5G SA mode.
You can try with LTE and NSA mode, the first PDP context will be activated by default.

Hi, Would you give an example of setting PDP using the AT+CGDCONT command? I tried alot and received errors each time. Additionally are there any manual pdf showing the meaning of errors and how to solve them.

Dear @Ahmed2
AT+CGDCONT is a 3GPP AT command, the error is listed in 3GPP document, you can check.
