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.

Thanks for the tip!. It looks like a USB powered Arduino Nano cannot handle the long range radios power requirements. I powered the radio module independently and I can send commands succesfully again!
The range has not improved, though, but that's another matter...
Thanks !
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.
I looking with a magnifying glass at the chip, i noted that this is NOT NRF24L01+ but just a NRF24L01 without the plus.
I used this smaller versions and they worked immediately. I_GATEWAY_READY message appeared. http://www.ebay.com/itm/2-4G-NRF24L01-PA-LNA-Wireless-Module-with-Ceramic-Antenna-1-27mm-/400746941364?pt=LH_DefaultDomain_0&hash=item5d4e610bb4
MySensors did post a warning on that: http://forum.mysensors.org/topic/728/radio-setup-give-check-wires/16
THREAD RESOLVED.
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.
