OK, until that gets sorted, I reverted to the prior copyStringToRadioBuffer definition for the current files posted on GitHub. That way anyone downloading the files should have something that works.
I also made a few upgrades:
1. Rather than running open loop and transmitting each packet 3 times, the receiver node now transmits an acknowledgement to the transmitter to let the transmitter know that the receiver received a valid packet and for the transmitter to please the next packet.
2. Upgraded from 1mbps to 2mbps over the air datarate.
3. Enabled data-whitening.
4. Now using a longer preamble on transmitted packets.
