Feature request: AT command to get the supply voltage
The simcom GSM modules have an AT+CBC command that returns the battery voltage in mV.
Could we please have a command that returns the supply voltage to the RAK811, using the ADC_IN17? - see this app note: http://www.st.com/resource/en/application_note/dm00035957.pdf
This saves adding a voltage divider to the main mcu, or allows for the RAK811 being on a different power source to the mcu.
Thanks your good suggestion, we will prepare add this cmd to next release version, and send you to test first .
