Re: BLE and WIFI simultaneously

There is this: https://developer.ibm.com/recipes/tutorials/experiments-with-bluetooth-and-watson/ but it is broken with the latest IDF code, and it never really worked very reliably always eventually failing with this: https://github.com/espressif/esp-idf/issues/442. After that I tried updating IDF ...

Re: ESP-NOW?

Ok thanks. Do you know if that problem I asked about on bbs.espressif.com with using ESP-NOW at the same time as WiFi on the ESP8266 really is a limitation, or am I just doing something wrong?

ESP-NOW?

Hi, does/will the ESP32 support ESP-NOW?
And if the answer is yes do you know will it support using both ESP-NOW and connecting to a WiFi access point at the same time (to fix this problem)?

Low power BLE advertising?

I'm trying to have an ESP32 use deepsleep to save power and wake up regularly to broadcast a BLE advertising message. It mostly works but there is some delay when waking up before the advertising message gets sent, so the ESP32 needs to stay awake for several seconds to have the message sent reliabl...

How to set the analog attenuation?

The code to set the esp32/arduino code to set the analog attenuation doesn't seem to work. Can anyone say how its supposed to be done? Or is there some bug in the SDK? Code is here: https://github.com/espressif/arduino-esp32/blob/master/cores/esp32/esp32-hal-adc.c#L69 Issue here: https://github.com/...

ADC max input voltage?

Hi, can anyone tell me the absolute maximum input voltage of the ESP32 ADC pins? I've seen a few blog posts suggesting 4.0 volts but I can't see that any any Espressif docs.

Also, does that change with the ADC attenuation setting?

Thanks!
