I'm trying to set up a remote display application.
Communication between two XBee S2's is working fine, transparent mode (AT), when I test PC to PC. However when interfacing with a Photon microcontroller, even at 9600 or 19200 baud, I am losing characters if I send strings vs individual bytes. I tried adding an extra stop bit with ATNB=3, to no avail.
If I send one byte at a time, I get fully reliable transmission. However my application is fairly timing-critical and I need fairly short latency. Any help / pointers is welcome...
