I found this document here back in the days - I guess it's wrong, isn't it?
const byte addresses[][6] = {"00001", "00002"};
// at the Transmitter
radio.openWritingPipe(addresses[1]); // 00001
radio.openReadingPipe(1, addresses[0]); // 00002
// at the Receiver
radio.openWritingPipe(addresses[0]); // 00002
radio.openReadingPipe(1, addresses[1]); // 00001
Also, is addresses [0] = 00002?
