I bought a Seeeduino Lotus and a Dragino NB-IoT Shield-B8 but I can not get it to work. I have mounted the shield on top of the Lotus like it should
I tried the part where you could connect the TX/RX of the lotus to the shield’s RX/TX but it does not work
I connected a USB UART to the debug pins of the shield
Tried putting a 2A charger to the seeeduino and seeing what it does in the serial monitor via the RX/TX but nothing changes so it is probably not a power issue
I am getting this in the arduino serial monitor when I reset the shield, so it does do something
And this in the putty (debug on the shield) when I reset it:
The “AT” etc. commands do nothing, does anyone know where I am going wrong?
