* Implement RadioText on Prais:
Device has 4 RT buffers (64bytes each) and we have to fill all of them or else we get garbage. Device supports a retransmission counter for each
buffer but when trying to use that functionality on the manufacturer's application I got an infinite loop, so for now each buffer is transmitted one
time. This is an ugly fix that "loops" a single 64byte message but it works for now. In the future we can implement a local RT buffer in sw to hold all
4 RT buffers and implement append and flush functionality.
