AT+CSQ always showing 99,99


  • Hi, I use the nb-iot T-Mobile sim (from dev-kit) in combination with the sara r410m board. After I installed the passthrough sketch and follow the steps at the Sodaq site I never get a connection. Always get a AT+CSQ always showing 99,99. Do I need to activiate the sim or something like that? Note that I get a connection using a Vodafine sim.

    Regards,

  • Hi Raymond, can you please share the config with us? Or just a copy paste of the AT command which you use to connect



  • Hi,

    I registered my device as UDP. These are the commands I used. I switched off and on the antenna (AT+CFUN=0 and AT+CFUN=1) multiple times. That could make a difference I found somewhere on a forum, but with no luck.

    AT+URAT=8
    AT+URAT?
    AT+CMEE=2
    AT+CGDCONT=1,“IP”,"cdp.iot.t-mobile.nl"
    AT+CGDCONT?
    AT+CFUN=1
    AT+COPS=1,2,"20416"
    AT+CSQ
    AT+CEREG=2
    AT+CEREG?
    AT+CGPADDR
    AT+USOCR=17
    AT+USOST=0,“172.27.131.100”,15683,4,"Data"
    AT+USOCL=0



  • Can you try it again and send us the results of the following 3 commands please?

    at+cgdcont?

    at+cereg?

    at+nuestats



  • Hi, just tried to issue the commands you suggested. Unfortunately I don’t get any AT output at my arduino serial monitor. Looks like after the first AT command the board get’s in a strange state. Need to solve this first in order to send you the results 😞

  • Hi,

    I already saw the thread and upgraded the firmware to the latest version. Still without luck. But, I am in contact with Sodaq for this AT commands issue. Once this issue is solved I will send the output of the commands you requested.

    Regards,

    Raymond
