I use the DFRobot_SIM7000_UDP sample code, and I meet a big problem that fail to attach service. I try a lot of function to connect the APN using AT+CSTT, AT+CIICR, AT+CIFSR those AT command, but i still can't attach service.

I saw very carefully your video on youtube and for me it doesnt show up easy like yours.

Plug the shield in directly and open command tester, try sending commands to see if you get a OK response

I cant see any of your uploaded images but if you change the baudrate you should be able to find one that allows you to see the at commands clearly over serial
