Question

I am able to get 4g signal info from gsmctl, for example gsmctl --sinr. But its only from the first of the dual bands of 4g. If I log in to luci, I can see both band signal strength at http://192.168.1.1/cgi-bin/luci/admin/status/network/mobile/3-1 and can find the info from the server side rest service http://192.168.1.1/cgi-bin/luci/admin/status/network/mobile_info?modem=3-1, typically named sc_band, sc_rsrp, sc_sinr

How do I get the signal strengths from cli for the second band? Or how do I find the code that is executed in the rest service?

Hello,

You can get carrier aggregation parameters with the command: gsmctl -A AT+QCAINFO

The response should look like this: 

+QCAINFO:

“PCC”,<freq>,<bandwidth>,<band>,<pcell_state>,<pcid>,

<rsrp>,<rsrq>,<rssi>,<sinr>

“SCC”,<freq>,<bandwidth>,<band>,<scell_state>,<pcid>,

<rsrp>,<rsrq>,<rssi>,<sinr>
