RM520N-GL - Unable to use QPING - Error 558 : Socket write failed

HI,

I just received an RM520N-GL device, and I would like to send some PING request, using AT+QPING commands.

When doing this, it’s not working, even if I’m registered to the network in LTE or 5G NSA, with an IP address. Is there a new FW to try ?

BR,
Mathieu F.

Here are some AT commands outputs:

AT+CGCONTRDP
+CGCONTRDP: 1,5,"internet","192.169.0.7",,"8.8.8.8","4.4.4.4"
OK

AT+QPING=1,"8.8.8.8"
OK

+QPING: 558

Dear @Mathieu
Please query your current firmware via AT+QGMR.
From the description of AT command, please sue AT+QIACT to activate the context firstly, then try again.

Dear @Mathieu
I tested on my side and it worked fine.
Please try to use AT+QICSGP to configure APN, then activate and ping.
