An error when opening information

An error when opening information.

I found that mccmnc.dat line ending is windows rather then unix.

Console log:

Hi, This modem is weird. It doesn't show much. You can try replacing the 3ginfo.sh file /usr/share/3ginfo-lite.

3ginfo.zip

Hi This is FM350 modem. I'm trying to update 3ginfo for fm350. Last release 1.0.65 has broken operator name.

here is logs: yours_3ginfo_sh.log my_modified_3ginfo_sh.log

Hi, @prusa-dev Check these at commands to see if you get a modem response:

AT+COPS=3,2;+COPS?
AT+CEREG=2;+CEREG?
AT+CGREG=2;+CGREG?;+CSQ
AT+GTCCINFO?;+GTCAINFO?
AT+GTSENRDTEMP=1
AT+GTPKGVER?;+CGMI?;+CGMM?;+CGMR?;+CIMI?;+ICCID;+CGSN?

[prusa-dev]

This is not problem of FM350, I think problem here https://github.com/4IceG/luci-app-3ginfo-lite/blob/main/luci-app-3ginfo-lite/root/usr/share/3ginfo-lite/3ginfo.sh#L306

Maybe there should be $COPS_NUM variable instead of $COPS

@4IceG Adding xargs solve problem with line ending

@prusa-dev Is the operator name shown after recent script corrections?

I don't know if I found it right, but I think these at commands +GTCURCAR? or AT+COPN or AT+COPN=? it also allows to show the operator.

or read from a mccmnc.dat file.

[prusa-dev]

No operator name is not shown.

Here is my COPS response:

sms_tool -d /dev/ttyUSB4 at 'AT+COPS=3,0;+COPS?;+COPS=3,2;+COPS?'

+COPS:0,0,"MTS RUS",7

+COPS:0,2,"25001",7

Please look at the 3ginfo.sh log:

+ awk '-F["]' '/^\+COPS:\s?.,2/ {print $2}'
+ COPS_NUM=25001
+ '[' -n 25001 ]
+ COPS_MCC=250
+ COPS_MNC=01
+ '[' -z  ]
+ awk '-F["]' '/^\+COPS:\s?.,0/ {print $2}'
+ echo '
+CPIN: READY

+CSQ: 9, 99

+COPS:0,0,"MTS RUS",7

+COPS:0,2,"25001",7

As you can see COPS variable is MTS RUS, and later script compare isp with COPS that contain non numeric operator name. I don't understand, why there isp isp_num isp_numws code block?

This means that part of the script with isp isp_num isp_numws needs to be corrected. This part of the code was supposed to read the operator name and its location in case COPS appeared as the MCCMNC value. This needs to be changed so that only numerical values are checked.

Hi, @prusa-dev Replace file 3ginfo.sh and check if error with the operator name has disappeared. 3ginfo.zip

[prusa-dev]

Hi @4IceG The error is gone, and the operator's name is displayed correctly.

Thank you!
