I am using a Quectel BC660K modem, connected with a battery. I keep the battery charged using a solar panel. I can send a command to the modem to report the voltage. The modem draws a lot of power to communicate, but the value drops below 1mA when I put it in sleep mode, and the battery recharges.How do you know the ADC_VREF is different each time, and why would that be ?
