One Answer:
If I understand you correctly, you are trying to capture the 2G GSM/GPRS protocol messages as define in 3GPP specifications, right? If yes it requires some specific logging function inside your modem and you will not be able to capture them with a standard Linux interface. answered 07 Apr '15, 06:33  Pascal Quantin showing 5 of 9 show 4 more comments |
Thanks so much for the replay. I have a program called M-Center from UBlox that works 100% on any windows system my goal is to see what information i can pick up from sending a text message (SMS) to a mobile device and see if i can identify its cell id from a force return message i know i can find the LAC but i am not sure about the cell id do you have any suggested interface for me
If you have access to a serial port allowing you to send AT commands, you can look at the ouput of CREG command when using n=2:
AT+CEREG=2
then do
AT+CEREG?
And the ouput should be
+CREG: <stat>[,[<lac>],[<ci>],[<act>]]
See 3GPP 27.007 specification for details.
the AT+CEREG=2 gives me a Error =(
Sorry I did a typo and wanted to type AT+CREG=2; AT+CREG? and not AT+CEREG (that is used for LTE modems). According to https://www.u-blox.com/images/downloads/Product_Docs/u-blox-ATCommands_Manual_%28UBX-13002752%29.pdf this command is supported so it should give you the GSM cell identity.
Seriously ! ! ! OMG your haven sent ! lol i been thru that site a good number of times got a lot of PDF's but i its the 1st time seeing this one THANKS a Billion
i have all the codes i would ever need but i don't have any idea how to send them to a mobile device for example
AT+CREG=2 OK AT+CREG=? +CREG: (0-2)
The manual does not give any clear examples where do we in put the cell phone number and how will it return what am i missing ?
You must type "AT+CREG?", not "AT+CREG=?"
I must be doing some thing wrong i cant send any commands it keeps sending them to the ublox and it only replays with OK or ERROR i am looking in to PDU and APDU right now maybe i can send and request it thru HEX messages
I have a USRP can i scan GSM packets with it in airprobe and scan airprobe with wireshark for example https://www.youtube.com/watch?v=FqtJ-TvtLTQ but how will i get a fixed signal on the ublox ?
