RM500U-CN firmware, flashing tool, and ethernet pdu sessions

IoT Modules 5G Module

Hello,

  1. Can you give me the latest firmware for RM500U-CN modem.
    Current firmware version (from ATI command): RM500UCNCBR03A02M2G
    at+gmr: RM500UCNCBR03A02M2G_01.001.01.001

  2. Are the 500U-CN and 500U-CNV modems completely different? I am working with Ethernet PDU sessions. 500U-CN modem does not seem to establish ethernet pdu session with the Cumucore core and airpuls RAN, while with the same setup 500U-CNV can establish ethernet pdu session

  3. Are there any specific commands to ethernet pdu sessions with 500U-CN?

  4. at+cgdcont? shows 3 pdp contexts, 1,2, and 11. at+cgdcont=2 sometimes is able to remove 2nd context but at+cgdcont=11 is never succesfull. why is that? 5G core is configured to only allow Ethernet sessions.

Thanks!

Hi @silvia
Thank you for the latest firmware. I had flashed it successfully. Earlier I had tried the firmware which was meant for 500U-CNV, thats why it hadnt worked.
at+cgdcont shows 2 or 3 sessions. Ethernet, IPv4v6 and ims. Out of these, only Ethernet context is active.
It is also confirmed by at+cgact command which shows 1,1 meaning Ethernet session active.
I guess completely removing(deleting) the ims context is not possible. I can remove IPV4V6 context sometimes via at+cgdcont=2, but other times it gives error.

Dear @abm44
IMS can’t be removed, please note this.
Why do you want to remove them, actually, if you don’t activate them, they don’t have any effect.
