Quectel RM502Q-AE 5G Sub-6Ghz and 4G fallback

IoT Modules
23

The antenna appears to be connected correctly.

Is there anything you could think I might need to do in order to ensure the modem is falling back to 4g in the situation where 5g isn’t available? (The promotional material all states that this modem falls back to 4g, but 5g is spotty where I am testing this, the phone falls back to 4g when it connects right here with this sim, and it is all I can think of.)

Thanks again for all of your help I do appreciate it. I am in the process of contacting sixfab but if I can just get this to work I will be happy.

Check with the following commands:

AT+QNWPREFCFG="nr5g_disable_mode"
AT+QNWPREFCFG="mode_pref"
25 
AT+QNWPREFCFG="nr5g_disable_mode"
+QNWPREFCFG: "nr5g_disable_mode",0

OK
AT+QNWPREFCFG="mode_pref"
+QNWPREFCFG: "mode_pref",AUTO

OK

0 Neither is disabled

All looks good to me.
