RM500QGL - not connecting to 5G SA N77 on 4.1 GHz


We’ve been having trouble to have the RM500QGL to register with a 5R NR SA cell at 4.175GHz in N77. The cell is returned by the module when using AT+COPS=? but no registration attempt is received by the gNodeB when selecting the network with AT+COPS=1,2,“00101” or AT+COPS=0.

Firmware version is RM500QGLABR11A03M4G.

Is this module limited to upper N77 frequencies?


Dear @Felipe_Luccas
Your current firmware is old, it is recommended to use the latest firmware to test.
