I have contacted Nordic on this issue (more later on that) but it seems the issue is on the transmitter. Here is a dump of the status register showing that MaxRetries is getting hit every other transmission at the start and end of every IRQ event firing.
Writing: 1 A5-A5-0C-00-00-FF
IRQ Start - Status: DataReady: False, DataSent: True, ResendLimitReached: False, TxFull: False, RxEmpty: True, DataPipe: 7, DataPipeNotUsed: False
Tx Data Sent Successfully
IRQ End - Status: DataReady: False, DataSent: False, ResendLimitReached: False, TxFull: False, RxEmpty: True, DataPipe: 7, DataPipeNotUsed: False
=====================
Writing: 2 A5-A5-0C-00-01-FF
IRQ Start - Status: DataReady: False, DataSent: False, ResendLimitReached: True, TxFull: False, RxEmpty: True, DataPipe: 7, DataPipeNotUsed: False
Send Failed - Resend Limit Reached - Flushing Tx Buffers
Tx Data Not Sent - Failed
IRQ End - Status: DataReady: False, DataSent: False, ResendLimitReached: False, TxFull: False, RxEmpty: True, DataPipe: 7, DataPipeNotUsed: False
=====================
