      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,

      Raymond

        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

              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

                    Hi,

                    Just want to let you know that Sodaq found the issue why sending data was not working. It turned out that an arduino sketch I was using did change the band somewhere underneath to 20 (which is used by Vodafone) After I changed the band (AT+UBANDMASK) to 8 manually, the T-Mobile sim started sending data.

                    Regards,

                    Raymond

                      Hi… I retried the following day with same AT orders and now I’m associated.

                      Utilizing +CSQ is see another worth and I get network measurements that before were zero.

                      At this point unclear why I didn’t have network yesterday on similar area and similar settings and AT orders.
