Can't get ip with RM502Q-AE and PLMN 99999

IoT Modules 5G Module
1

Hello,

I am trying to attach RM502A-AE with a private 5G SA network with plmn 99999. I performed many tests without success. When i change the plmn, the connection is established.
How might I go about troubleshooting this? are there any restrictions to use this plmn?

Setup:

  • RM502Q-AE
  • Dual Gigabit Ethernet 5G/4G Base Board Designed for Raspberry Pi Compute Module 4.
  • I flashed the sim card with the desired plmn

Dear @LucasM
What is your current firmware?
Why did you want to use PLMN:99999? Is it possible to use other PLMN for testing?

Problem resolved.
The PLMN 99999 was a requirement.

I modified the following parameters:

  • AT+QNWPREFCFG=“mode_pref”,NR5G
  • AT+QNWPREFCFG= “nr5g_band”,78
  • AT+QNWPREFCFG=“nr5g_disable_mode”,2
  • AT+CGDCONT=14,“IPV4V6”,“xxxx”

Reboot the module and OK

Thanks for your support
