Hi,

I noticed that very often the fibocom returns as CSQ value 99, 99, this problem implies the entire dashboard of 3ginfo not showing the data:

"csq":"-",
"signal":"0",

+ awk '-F[, ]' '/^\+CSQ/ {print $2}'
+ CSQ=99
+ '[' x99 '=' x ]
+ '[' 99 -ge 0 -a 99 -le 31 ]
+ CSQ=-
+ CSQ_PER=0
+ '[' -z - ]
+ '[' -z 0 ]

Is there a way to solve it?

Thank you

Hi,
How to fix this?
Find another command to get CSQ from when the modem shows "unusual value". I'm almost afraid to look at the manual for this modem.

Find another command to get CSQ

The problem that there is no other way to get the data, the only way is via AT commands, which is causing this problem, I had to put the value 1 on both variables to keep it from looping, this however will report 1% signal when the value is invalid, but it doesn't trigger the 3ginfo interface loop. I don't understand if it's a module problem or a firmware problem, I updated it but nothing changed

Same,
with Fibocom FM350-GL module sporadically the connection is interrupted and it is not possible to view the metrics.
Instead through AT commands it is possible to request the information continuously.
It is possible to fix the problem?
Thanks!

原因是fm350的at命令无法获取csq的值，只要修改一下/usr/share/3ginfo-lite/3ginfo.sh这个脚本就可以使用。
3ginfo.sh.txt

openwrt 需要安装bc软件包 opkg install bc

I also got this one with my modem. I quickly fixed that by putting 1 if CSQ is out of range. I think the proper fix would be to allow undefined value and just let the user see all the rest of parameters even if signal is empty.
