I have 2 Xbee Pro S2 and 2 Xbee Pro S2B.
My issue is communicating with these devices using the End Device Function set.
When I program any of them with the Coordinator or Router Function Set I am able to communicate with them both via the XBEE-API or the X-CTU with no issues. However when I attempt using the End Device Function set with any of them communication with the device becomes intermittent, even with X-CTU.
Has anyone come across this issue?
