Hello I have RM520n-gl modem and the problem is I can’t reach 5g connection. Do I need attach all 4 anntenas to this modem? I have supposedly 5g sim-card from our provider.
AT command below
Also you can try to lock to 5G with following command to test.
AT+QNWPREFCFG=“mode_pref” // Query the current network search mode
AT+QNWPREFCFG=“mode_pref”,NR5G // Lock to NR5G
AT+QNWPREFCFG=“mode_pref”,LTE:NR5G // Lock to LTE and NR5G
Hello, I’m testing again the RM520N-GL 5G module. There is still problem to reach 5g signal.
Some additional informations from AT query:
Module FW - response: ‘RM520NGLAAR01A05M4G_01.001.01.001’
After last AT+QRSRQ it looks like module only read signal from 2 antennas out of 4. I’ve connected all four antennas.
I am still available to get LTE connection only.
I don’t think this firmware is causing it, if you want the new one you can find it below, please read the Release note to decide if you want to upgrade. RM520NGLAAR01A08M4G_14.201.14.201.zip
