I bought a Seeeduino Lotus and a Dragino NB-IoT Shield-B8 but I can not get it to work
I have connected the Dragino shield on top of the Seeeduino (as it should(?))
I follow this tutorial: <LINK_TEXT text=“https://wiki.dragino.com/index.php?titl … o_Mega2560”>https://wiki.dragino.com/index.php?title=NB-IoT_Shield#Test_NB-IoT_Shield_with_Arduino_Uno_.26.26_Arduino_Mega2560</LINK_TEXT>
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

OK<e>
And this in the putty (debug on the shield) when I reset it:
The “AT” etc. commands return nothing, does anyone know where I am going wrong?
