Thank you Nca78.
The radio module has been connected up exactly as per the "Connecting the radio" page:
GND GND
3V3 VCC
D2 CE
D8 CSN/CS
D5 SCK
D7 MOSI
D6 MISO
I found the log parsing page after I posted and it was useful. Since then I have changed the cables for shorter duponts and used another nrf24l01 radio with the same result. What I haven't tried yet is the "add a capacitor to the power supply".
Would I be correct in thinking that according to the log file, the radio is being initialised and therefore appears to be wired correctly?
The capacitor thing is well documented, has anyone had to do this? If so, did it solve the issue?
The Arduino nano side of things is using one of those adapter boards with the built-in regulator so am thinking it may be a power issue?
