HI! Have the same problem.

Analysis of the file output /usr/shared/3ginfo-lite/3ginfo.sh showed that variables EARFCN, SINR may contain a carriage return character (\r). On some routers this corrupts the json output. I added (tr -d '\r') command to the script to remove the \r character and everything works fine.

After updating to the latest snapshot I was getting the same issue "JSON bad control character".
Examining the output of the 3ginfo.sh script I found that the TEMP variable contained the carriage return character. So I manually edited the command used to retrieve the TEMP in the modem/usb/modem_ID file and added a pipe to sed 's/\r//g'.
