Thanks
Maybe you also advice how to trick Master branch (not Development branch) on the same way to disable radio and achieve coexisting of the serial gateway and node on the same arduino connected to a controller via usb?
Examples at the Development branch have explicit definitions for using radio, which I can comment out
//#define MY_RADIO_NRF24
//#define MY_RADIO_RFM69
Meanwhile the master branch examples have no such definitions and assume the radio is always present, so I cannot disable it and it cause radio init errors for my case
