. Minimal power consumption of about 70mA when doing nothing and above 100mA when when transferring data makes it rather impossible to use it on battery power for a longer period of time I used my voltage/current logger to measure this. With the above measurements I can now do the real world calculation of the battery consumption. Maybe there is the opportunity that an esp32 provide this in real time without rebooting or two esp8266 connect to each other ESP32-EVB is OSHW certified Open Source Hardware with UID BG000011.
