I’d like to get details about “hub.set” parameters “vinbound” and “voutbound”.
First, the mode of “card.voltage” need to be set. The setting “lipo” set these values: “usb:4.6;high:4.0;normal:3.5 ;low:3.1;dead:0”. I guess that when the voltage is above or equal to 4.6V, the “usb” setting is used, when the voltage is lower than 4.6V and higher or equal to 4.0V, the “high” setting is used and so on. But, for the setting “l91”, the values are “high:5.1;normal:4.8;low:4.2;dead:3.9”.
First question: What happens when the voltage is below 3.90V?
Second question: Is there an hysteresis when voltage is around a threshold?
When the power source is under high load, the voltage may be lower than when the load is low.
Third question: Is the voltage read at a specific moment (load, no load) or it’s random?
