The quote is from this sample : Measuring and Reporting Battery Level
Use a 1MΩ (R1) and 470KΩ (R2) resistor in series, connected to the positive terminal on the battery and ground and then connected the tap point to the A0 input on the CPU.
The tap point could be bypassed with a 0.1 uF capacitor to keep the noise level low, at this otherwise high impedance point.
@electrik, yes I use gpio numbers. Sketch is very very long, I am porting it from esp8266 to esp32 wroom. Fixed different timers, from os_timer_t to hw_timer_t, less relevant, now the nrf24 switch. CE attached to gpio 17 the nrf24 Works fine, want to move to gpio 12, with the #define i mentioned, CE just stays at gpio 17
@electrik no it does not, CE to 17 is just my problem, with the ESP32 wroom-32u pin 17 is the serial2 txpin I need for Nextion output. And #define MY_RF24_CE_PIN 12 does not Work.
Have bought a ESP32 Dev with 38 pins. Try to connect my NRF24, got a problem with CSN and CE, there is no standard pin. GPIO 5 for CSN is ok CE on GPIO17 is blocking u2TXD I need. Try with #define MY_RF24_CE_PIN 12 to get CE to GPIO 12 no luck. Somebody did the job before, and did succeed, how?

with a little help from my friends ……..
Indeed, helping each other is not pointing with kingsize letters to obsolete software or leaving the thread there without any warning. Sorry if I was carried away with my anger after trying for a day to get things working.
@yveaux Well this is your description: "Installation As you can see in the description above, the console application and Wireshark dissectors are currently only available for Windows (anyone who volunteers to port them to Linux and/or Mac, please do so and let me know). In the description below I assume you've already downloaded and installed: Wireshark - I used 1.10.8, either 32- or 64-bits"
Well I suppose you meant it is only working with Wireshark - 1.10.8, that's really only using "Oude Meuk" Sorry I wasted my time, and I see too late more people did.
Wireshark is version 3, MySensors 2.3.1 released 2018. nrf24 protocol with old dll is not working. Cost me hours tot find out it is "Oude Meuk", and not working with Wireshark error message "dissector not found". Please @Hek and @Yveaux release working version or wipe it from the forum at many places, PLEASE!
This ino is working for me, it has the sleep function to save batteries. The Adafruit en the github/mysensors-> https://github.com/schizobovine/VEML6075 lib gives far to high index with my sensor. Only uv a and uv b declaration is not correct. Uv expect a index 0 till 11, domoticz controller passes a lower figure when it receives a number above 11.
