How to increase the stack size?

[rfenouil]

Thank you for this work, this library is awesome !

I am using the 'esp32-ble-multiple' template to connect to 2 BMS (ebike batteries), and when I add too many sensors I get into the boot loop problem.

I tried increasing the stack size as you suggested here, but it did not help:

esphome:
  name: ${name}
  platformio_options:
    build_flags:
       - -DCONFIG_ARDUINO_LOOP_STACK_SIZE=65535
  comment: ${device_description}
  project:
    name: "syssi.esphome-jk-bms"
    version: 1.4.0

I also tried to set DARDUINO_LOOP_STACK_SIZE as I found a reference to this name during my search but it did not help either.

Can you spot something wrong with my declaration above ?

Thank you for your help !

My esphome version (docker): 2023.3.2

Sorry for the naive questions, I am not familiar with esphome/arduino ecosystem...
Should I reset the flash with esptool when changing such options, or is everything overwritten ayway ?

Just in case I also clean the ".esphome" folder from time to time... Not sure if that has any impact though :)

I don't know the answer of your question. It's possible the define doesn't work because it's for the Arduino framework only. May be the setting is different for ESP-IDF. Could you ask for help at the ESPHome discord channel and share the solution here?

Ok, I'll try to get some info and report back.
Thank you.

Sorry to hijack this thread by maybe my question fits here and I don't need to open another issue. 😬
Why are you using the framework setting esp-idf for this esphome component and why doesn't it work with the default (arduino)?

I tried it out of curiosity. It compiled but the esp did not react after the flash anymore so I had to reflash it via USB. ;)

In the past the Arduino framework wasn't able to handle the 300 bytes BLE notifications from the JK-BMS. It did crash on the first received message. Some people reported it does work in general now. The Arduino framework is an additional abstraction layer on top of ESP-IDF. I try to avoid additional/unnecessary layers if possible.
