var spi = new SPI();
spi.setup({sck:A5, miso:A6, mosi:A7});
var nrf = require("NRF24L01P").connect( spi, B0, B1 );
That'll work on any pins, and should avoid any issues there may be with hardware as it uses just normal GPIO. If that doesn't work, maybe it's something as simple as a power supply issue?

Just a thought: What about using software SPI?
