I have mixed Nanos, Pro Minis, ESP8266 and Unos and no problem. I do however have mixed NRF24L01 and NRF24L01+ due to a bad AliExpress saler that stated he sold NRF24L01+ which in fact were not the + version. So I have set my baudrate on all nodes to 1mb. In order to be helpful we need the log on the Uno.
