RM520N - Cell Tower Lock

IoT Modules 5G Module

I’m having issue with QNWLock on RM520N-GL (RM520NGLAAR03A02M4GA). After locking, I’m not able to get back online. Once I reset, it is back online and locked, but it is unstable and disconnects at times. See below when I lock. When I unlock and reset, it’s back to normal function, but no locking. I also tried other towers, same issue.

Dear @whosvince
The RSRP of cell is -106, it is not good.
This command does not support locking 5G cells of NSA. And it is not recommended for commercial use.

This is 5G SA. The lock does work on a GL.INET router that uses RM520N.

Any idea how to fix or do I have to wait for new firmware? is RM520NGLAAR03A02M4GA the latest firmware for RM520N?

Dear @whosvince
Please try to test the latest firmware.
As mentioned before, it is not recommended for commercial use.
