Wireless Joint

Hi,

I'm looking for help on how to make my Waveshare SIM8200EA-M2_5G_HAT connect to 5G. I'm able to connect my RPI4 to the SIM8200EA module. Everything seems to work fine. The problem is that the module connects to LTE only and for some reason does not connect to 5G.

To sum up, when I send the command "AT+CPSI?" after turning on everything I get the following response:

+CPSI: LTE,Online,268-03.0x1D,215317,159,EUTRAN BAND3,1500,5.5,-194,-876,-485,-4

I then try to force 5G with the command "AT+CNMP=71" but it doesn't work. The internet is lost and the command "AT+CPSI" now returns:

+CPSI: NO SERVICE,Online

I have also tried to do

AT+CSYSSEL="nr5g_disable",0
AT+CSYSSEL="nsa_nr5g_band"
or
AT+CSYSSEL="nr5g_band"

but keeps not detecting 5G.

I'm trying to solve this issue for several days and any help would be very welcome.
Thanks!

You're certain you have the bands available that it can connect to?

Hi, and sorry for the late reply. I thought I had but now I'm not sure. I have a Samsung with 5G (M23) that with the same card informs in bars icon that 5G is connected. However, I installed an app that informs which frequency and band I'm connected with, and it says B1, which is 4G in my country.
