Need help reproducing issue at esp-idf github

Hi ESP32 devs, I am trying to debug a BLE issue with ESP32 and Android. When I try to combine BLE multi-connect and Android auto-Connect I get disconnections and can't keep a connection open. https://github.com/espressif/esp-idf/issues/1263#issuecomment-364751036 I would appreciate if people can try...

Re: Battery voltage reading via ADC

Hi iot_guy, Thanks for your suggestions. I also wasn't able to find information about the ADC input impedance of the ESP32. By "switching the divider", do you mean using a transistor of some kind or is there a better way? By using a buffer, do you mean using a capacitor in series or is the...

Re: ADC input impedance

I am also interested to know this. Wasn't able to find this in the datasheet.

Re: Battery voltage reading via ADC

What value resistors are you using in the potential divider? How are you calculating the voltage values from the ADC binary value? One of the things to consider is that the divider will add series impedance which will act with the ADC input impedance to form another divider. This is why buffers are...
