Hello, I have a Mega, a Nano and a Uno. Using the Mega as the Server and the Uno as the Client the RadioHead datagram works fine on both.
If I use the Nano in place of the Uno, same code and turn power off to the Uno the Nano returns "SendToWait failed."
After watching a Julian Lett video (can't find it right now) some time back he showed there is a different boot-loader in the Nano to the Uno and he over-wrote the nano with the Uno loader and it then thought it was a Uno.
I do not want to have to over-write the bootloaders of the Nanos.
How can I get this working with the Nano and it's standard boot loader?
