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.
Hi Raymond, can you please share the config with us? Or just a copy paste of the AT command which you use to connect
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.
Can you try it again and send us the results of the following 3 commands please?
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
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.
