I am using an Arduino zero to send SPI messages through XBee. I have configured all of the SPI pins to their respective SPI functions in XCTU, and am using API mode 1 (API mode with escapes).
I then send an SPI message with API frame via SPI, after driving SPI_SSEL low. I can see with the scope that the message is received at the MOSI pin, and the SSEL does in fact go low, however the message is not being transmitted and I cannot pick it up with another Xbee connected with a Dogo explorer to my computer on XCTU.
Is there something glaringly obvious that I haven’t done?
Thanks in advance.
