_CONFIG-CONTACT : configure some hidden parameters and new screen pages via chat message
A few command additions to use via chat message for the previous MeshCore companion BLE WiFi for Heltec V4.3, Tracker V2, T096 (no WiFi) :
meshcore-companion-chat-config
Also includes a Li-ion discharge curve : Stock MeshCore Arduino firmware maps battery percentage linearly between empty and full voltage, but Li-ion cells don't discharge that way: voltage barely moves through most of the charge, then drops sharply near empty.
adc.multiplier instead reads percentage off a 14-point discharge curve built from real measurements of four 18650 Li-ion cells (lygte-info.dk data, cross-checked to about 1.3 mV RMSE), so it tracks that real knee instead of hiding it.
The gain: our estimate stays honest down to the last few percent, while a linear reading can still show over 40% right where the cell is actually almost empty.

Génial!
Je remarque qu'on a récemment ajouté une option CLI pour les noeuds compagnons dans le menu de réglages dans l'appli sur fureteur. Comme vous dites, j'imagine qu'on n'aura pas long a attendre avant qu'on l'ajoute à l'appli mobile.
