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.
Sorry for my NRF24 clone post yesterday. The ACK bit was an issue with the NRF5 platform. I had switched the memory region to handle TX/RX/ACK packages separately. Sometimes the received packages are written in the wrong region. I had seen my testing ACK bit. Now, I have changed my NRF5 code and I can't see no difference between the modules, I have. ACK and timing are exactly at the same level.
Okay, finally got the original nrf24l01 SMD modules with the square chip visible... As exptected, things work just fine now, so the culprit of my issues was really the incompatible/fake "nrf24l01" SMD modules with the epoxy blob. If you want to use normal nrf24l01+ modules together with this smd gateway, DO
NOT USE the smd module with the epoxy blob, as they won't work.
Using only the fake SMD modules might work, too, but mixing the fake modules with real ones does not work.
@TheoL No damage. Water went up about 7 feet on our lake but had another 11 feet to go to threaten our property. Biggest flooding was to the south of us. We did have a fun time hiding out in our laundry room during tornado flying up to the east of us. Also, I do not think the radio is dead - hooked it by accident to my Uno testing board and it was transmitting just fine. Love these things - very tough.
