Interpretation
This establishes phase-1 behavioral equivalence for the protocol-core fragmentation/reassembly layer. The C++ code is not yet integrated into BLEInterface.py for live Reticulum/BLE traffic.
Tests on Pi Zero 2W
Note: I had to install the following on zerodev1:
sudo apt install python3-pybind11/stable
sudo apt install python3-distlib/stable
sudo apt install python3-setuptools/stable
sudo apt install python3-pytest
sudo apt install python3-pytest-asyncio/stable
I performed:
git pull

Real Life Tests
I tried running the Constitution real life tests, the results were the same, e.g. 36 seconds. I ask Codex:
I want to confirm that this command utilized the CPP library:
BLE_RETICULUM_FRAGMENTATION_BACKEND=cpp timeout 60 python3 examples/ble_dual_node_echo.py \
--ble-role both \
--message-file /home/jlpoole/US_Constitution.txt \
--peer 926e6d3b35b7d5940be7edeb47c41b78 \
--announce-only-when-disconnected
and the response was "No, that command almost certainly did not use the C++ library."

Hello/handshake RX records:
zerodev2 -> zerodev1 recv=04:44:32.951 latency= 118.171 ms message='hello'
zerodev1 -> zerodev2 recv=04:44:32.963 latency= 113.954 ms message='hello back'
Caution: one-way latency assumes sender and receiver clocks are synchronized.
Your chronyc tracking output helps bound this error, but it is not a substitute for ACK/round-trip timing.
