NRF24L01 library problems

I've been struggling with exactly the same setup and libraries. I've ended up dumping out the register contents of the NRF24L01+ from both the Espruino side and the Arduino side and tried to line them up. There were some basic differences like bit rate and channel which I've sorted out but still almost no joy. I've managed to go from silence to maybe one transmit in 30 or 40 being received by the Arduino if the Espruino is sender and similar success rate if I swap them around.

The RF24 Arduino code works perfectly on a mix of Pro Minis, Unos and DigiX but just getting no joy on Espruino. The only thing I can think of at the moment, in lieu of an oscilloscope, is to get a second Espruino and see if they can at least see each other.
