Each #MeshNetworking radio test cycle requires rebuilding and uploading separate #ESP32S3 firmware images 4 each #TBeamSupreme, because each unit has different blocker rules to simulate network topology.

Moving the compile step from my older Intel workstation to a Ryzen 7950 box cuts roughly 8–9 minutes from each iteration. That adds up fast when testing, retesting, and chasing radio anomalies.

Debugging #microReticulum LINK/transport behavior over LoRa is hard when the “wire” is invisible.

I’m testing BOB, CY & DAN, with DAN acting as the middle node between two units that cannot hear each other directly. To look for possible RF collisions, I modified #OpenWebRX.

It is fuzzy, but it turns millisecond logs and invisible transmissions into something I can actually see.

Looking at two Rust paths toward #Reticulum: Reticulum-rs, a smaller MIT-licensed library, and Leviculum, a much broader AGPL implementation with a no_std core, daemon/CLI, interop tests, and embedded ambitions.

My practical question: could either help with #ESP32 / #TBeamSupreme transport work, or does #microReticulum still win today?

A house is not a building code.

I wrote about using ChatGPT + Codex to derive a protocol specification for Reticulum/LXMF from its Python implementation—turning “look at the source” into something closer to a language-neutral contract, with test vectors to follow.

Herding T-Beam Cats: my practical test bench for running 7 LilyGo T-Beam SUPREMEs with PlatformIO, synchronized clocks, serial monitors, structured logs, and Codex-assisted debugging bounded by actual evidence.

I used #Bluetooth / #BLE as a short-range stand-in for #LoRa to test #Reticulum mesh behavior with #TBeamSupreme units.

The RSSI graph worked: carry two units away from a base pair, watch signal strength decay, disappear, then recover on return.

The GPS trace? Woeful. Useful lesson: RSSI test succeeded; urban T-Beam GPS precision did not.
