How to connect ESP32 Dev Board to Cayenne?

Ideas / Suggestions
1

I was using ESP8266 Development board with Cayenne for opening and closing the garase door, but when there was no communication for some time, the ESP8266 went offline. If I wanted to use my phone to open it, I had to first press to open and then wait for it to come back online. This could take 10-20 second. Then it was online and working find. The ESP8266 was also using a lot of power, so my battery operated 8266 lasted only for three days before the battery was flat. With the ESP32 I am hoping for long life and hopfully always on, but it would not compile with the ESP32 code and Cayenne libraionry. Any suggestions?

When I looked at the error message, I found this:

analogWrite(pin, it.asInt());

So maybe it is “analogWrite” that is not implemented in the ESP32 software yet?

From: espressif/arduino-esp32

analogWrite() not implemented #4

two types of analogWrite are now implemented through SigmaDelta and LEDC.
Headers for the relevant drivers are here and here

So maybe I just need to wait sometime, or is there some adjustments I can do like putting in some extra headers?

Hello @svein.utne,

Have you been able to connect your esp-32 to MyDevices?

Thanks,

Are you referring to native support for the board at mydevices?

Yes

Looks like I either keep trying or wait:slight_smile:

Yes from what I saw last time I looked analogWrite is not yet supported. It’s a shame, the 8266 took off right away but the 32 seems to be dragging on forever. Soon…
