I’ve been trying to communicate with the Sodaq Sara R410M Ubee module (connected to an ftdi) using AT commands. I’ve put the Ubee on a sparkfun breakout board (https://www.sparkfun.com/products/11373). I’ve connected:
rx -> tx
tx -> rx
3v3 -> vcc
gnd -> gnd
dtr -> dtr
rts -> rts
When I send the commands through a serial monitor, I don’t get a response. I have also tried the same setup with an Arduino Uno with the same result.
Can anyone help me with this?
