Issues uploading to ESP32 device

[tevaadarelsol]

Hello mate,

Trying to upload your code to an ESP32-WROOM-32 device causes bootloop. Logs attached. Is there any way to solve it?

Thank you so much, I really appreciate your work as you bring us the possibility to make our aircons intelligen without having to waste so much money by replacing them!

Hi @tevaadarelsol, did you manage to get it running? I just got my ESP2-WROOM-32E today and I have exactly the same problem as yours. Thanks!

[tevaadarelsol]

Hello @thaenan. I had no time to put my hands on It again, but was trying to get It working without success.... It would be nice if @rabbit-aaron could give us a helping hand.

[rabbit-aaron]

Sorry, I'm not too familiar with the ESP32 variants, I used ESP32-S, if you could get your hands on one that'll probably work.

I am no expert on the ESPHome either so there's little I could do. Would be nice if someone figure this out and could post an answer here.

But by looking at the error messages I have a guess, maybe the chip isn't able to establish a connection with the indoor unit, thus the task failed to finish and failed. Please post some photos of your circuit here as well.

[thaenan]

Hi, actually this solution proposed in the HA community forum worked for me: https://community.home-assistant.io/t/fujitsu-ac-heat-pump-integration-via-esphome-esp32/407610/102?u=dosreism.

modified in the library file “FujitsuClimate.cpp” in the setup function the xTaskCreatePinnedToCore() statament changing only the priority parameter to 1

THANK YOU SO MUCH @thaenan !! This was the problem, I think I've searched on ALL the internet looking for solutions except for the most obvious place: the own development thread (facepalm).

After changing this parameter I was able to upload it. However the ESP32 didn't communicate with the aircon. At the same thread someone explained there is a dip switch that must be changed and, after that, I managed to get It working flawlessly.

Huge thanks to @rabbit-aaron for the contribution and @thaenan for pointing me on the right direction!

Another reason why you might have bootloop is due to the LIN transceiver not being correctly connected, note the Rx connects to Rx and Tx connects to Tx, unlike other UART connections.
