Unable to set n257 as preferred band on RG530F-EU module

IoT Modules 5G Module

Hi, I have a RG530F-EU module in 5GDM01EK evaluation kit. I received the latest firmware from our supplier, which was supposed to solve other issues.

We try to connect the module to 5G SA in n257, so I try to set the band as preferred one with:

AT+QNWPREFCFG=nr5g_band,78:257

It returns:
+CME ERROR: 735

Any hints are really appreciated.

Regards,

Dear @duhovnikov
Please share your current firmware.

AT+QNWPREFCFG=“nr5g_band”,78:257
or
AT+QNWPREFCFG=“nr5g_band”,257

Dear @silvia

The issue has been resolved through another support channel with FR2 SA application note.

There is an application note FR2_SA_Application_Note, that you @ quectel should have it. Unfortunately, I cannot share it as the document is labeled as confidential.
