Hello PJ,
Been awhile! I put it all up for a bit as the more I got into it the more I got confused. As a reminder all I want to do is make a little handheld transmitter that will allow me to send commands to a receiver which will control the speed and direction of a small DC motor and turn on and off a few leds. In addition I want to be able to select different receivers from the same transmitter. I have a bunch of the Seed XAIO nRF52840 boards along with the Expansion board and the little dongle. Any chance you can steer me into a few examples showing what I am trying to acheive? Thanks you - regards Alan in MN USA
