ESP32-C3 compile error

[JesperThorup]

Trying to use the Lolin Wemos C3 Mini to use the bluetooth, but i'm getting this error on compile:

Does enyone know what that means?

[syssi]

Could you provide your configuration yaml? I would like to know the board section of your configuration to be able to reproduce the issue.

@syssi sure thing...

@syssi Got it working on another board and connected using bluetooth, but all values are 0...

[syssi]

It looks like you have flashed the example for the Heltec smart balancer. Please use the esp32-ble-example.yaml instead to talk to a JK-BMS.

[syssi]

If you are using the esp32-ble-example.yaml already please increase the log level by:

logger:
  level: VERY_VERBOSE
  logs:
    scheduler: DEBUG
    component: DEBUG
    esp32_ble_tracker: DEBUG
    sensor: DEBUG

and provide another log capture. I'm interested in the 300 bytes raw frames (the response of the BMS).

[JesperThorup]

@syssi This is the output with more logging:

https://pastebin.com/6ykSwRWK

[syssi]

Please use protocol_version: JK02 and try again.

[syssi]

It looks like you have used the esp32-ble-jk04-example.yaml as starting point. This is the example configuration for hardware version 4 of the JK-BMS. Please try esp32-ble-example.yaml as starting point.

[JesperThorup]

It works!! :) Thanks..

[syssi]

If you want to use the ESP32-C3 you have to change the board section slightly to re-enable BLE 4.2 feature of the ESP-IDF framework:

esp32:
  board: esp32-c3-devkitm-1
  framework:
    type: esp-idf
    version: latest
    sdkconfig_options:
      CONFIG_BT_BLE_42_FEATURES_SUPPORTED: y
