Blue manual

Setting up and running a DENKO Blue lightning station — the DENKO Blue firmware for the System Blue lightning-detector controller.

Start here

Quick start — connecting the station, finding its address and checking its readings.

Chapters

The Live page — the station's front page: the health line, traces from all four inputs, the lightning confirmation, the survey, the spectrum views, the detector controls, and the language selector.
The Signal chain page — antenna to ADC as a live diagram: input paths, the two gain stages, the filter, and what is measured versus declared.
The GPS page — the sky plot, signal bars, reception verdict and cause, timing lock, and satellite receiver settings.
The Tests page — the response sweep, the gain ladder check and the alias survey: the three hardware self-tests.
Firmware updates and stock conversion — automatic updates, USB (DFU) installation, and converting the board to the stock firmware and back. Read this one before touching the Firmware page.
Settings and station identity — where each value comes from, every setting, and the local station number versus the one the lightning network assigns.
Lights, verdicts and messages — the indicator LEDs, the health verdict, registration notes, and network states.
The Diagnostics page and the JSON API — every reading the station publishes, the firmware-update history, and the machine-readable endpoints behind the pages.

The station's own web interface speaks fourteen languages — see chapter 1.
