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.
New to electronics and progamming.... hence excuse rather dumb nature of my query .. recently purchase the Devduino V2.2 OTA version and am trying to figure out if the device comes pre loaded with the arduino bootloader. ??
I have published all the documentation in a Github repository. If someone wants to make PCBs, I recommend that you wait a little longer until you receive my PCBs and try them.

@Puneit-Thukral
Could you post your full working sketch please?
I'm revisiting some of my 51822 nodes that have sat collecting dust for a long time and thought i might try to get them working again.
