I have a Mesh consisting of 1 Argon and 1 Xenon.
My Argon sketch resets the Xenon and then resets itself (System.reset). After that, both units flash green (as expected), then the Argon connects to the cloud (as expected). However, the Xenon keeps flashing Cyan and then a single red and then cyan … Basically, the Xenon never connects back to the mesh.
The only way to have the Xenon reconnect is by pressing its reset button or by recycling power to BOTH units.
Placing the statement below in the Xenon code does improve things but the problem still occurs.
