Topic: Is RemoteXY touchy about it's refresh rate ?
Has anyone got any idea why this sketch only allows RemoteXY to communicate if void loop() is remarked out.
With it in the code I can't get RemoteXY to connect at all, I get Error Device not reply.
I can see that it is a timed execution loop, but I want RemoteXY to be able to connect to set filter parameters etc., I can disconnect to see the effect of the changes....
