The node is a very simple one. So I never considered boot loaders, as the node would not need changing sketches during it's lifetime. I have boot loading functionality on my other designs, this one is a minimal board. Any extra chip would beat the purpose of the word "minimal".
It's a dumb node for a reason
In the BACnet protocol, the messages are not sent directly, but pushed into an internal state machine that remembers (some) of the previously messages sent (i.e. memorize(_msg); send(_msg); ).
The state machine also peeks incoming messages and can trigger a message re-send in case of a missed ACK.
the difference with MySensors is that all the messages are numbered, otherwise you would not know which message of the last N sent previously was ACKed,
but well.. ACKing the last similar message might be good enough.
Anyway @SiLeX : if you want to try, this is not that complicated, (if you don't take into account the STREAMs) it will just costs about (1 status byte + 1 timestamp + 1 frame size) x N ; for N frames memorized.

Hi @acb and others, regarding "Do you know if there is a version of this board that is pad-compatible with the C-versions of these HopeRF RFM69s before I go searching? (Since I believe the C-versions are also pad-compatible with the RFM95sā¦)" - did you find any alternative?
I'm in the same boat looking for an adapter from NRF24 to the footprint of RFM69*C = RFM95/96.
Thanks, Joost
FYI: RadioHead library 1.34 has some specific initialization code for RFM73 in the nRF24 driver (e.g. ACTIVATE command).
See https://github.com/Yveaux/RadioHead/commit/f895ba933950681234d714fd7c3d3c18658b8ed5
Hello, i'm making some progress; received the components this week.
Unfortunately it doesn't work... yet
For now i have SanityCheck failure in to logs.
I'm afraid my soldering of all these little components is not good. I tested with a multimeter the 4 pins and i have continuity on one of them but maybe not the others so i guess i will have to try remelting all these small regulators ???
