Compile error with Lilygo T-Dongle-S3

[HBK1]

Dear Fabian! I am trying to use a Lilygo T-Dongle-S3 but get errors when I compile the alde repository. (Same error with truma repository) Is this an ESPHome error or is it in truma-inetbox?

Config:

esphome:
  name: alde

esp32:
  board: esp32-s3-devkitc-1

external_components:
  - source: github://Fabian-Schmidt/esphome-truma_inetbox@alde

ota:

  port: 80

logger:
  baud_rate: 500000
  level: VERBOSE

uart:
  - id: lin_uart_bus

    tx_pin: 43
    baud_rate: 9600
    data_bits: 8
    parity: NONE
    stop_bits: 2

truma_inetbox:
  uart_id: lin_uart_bus

number:
  - platform: truma_inetbox
    name: "Target Room Temperature"
    type: TARGET_ROOM_TEMPERATURE

If I omit logger or point to UART1 it compiles so the error seems to be the default logger uart USB_CDC that S3 uses.

logger:
#  hardware_uart: USB_CDC
  hardware_uart: UART1
  baud_rate: 50000
  level: VERY_VERBOSE

If I comment out the Truma parts it compiles with USB_CDC without problem. So it looks like there may be something in your files that needs updating to support USB_CDC for logging.

When I compare uart_component_esp32_arduino.cpp and uart_component_esp32_arduino.h with the esphome repository it differs and the esphome repo seems to handle the logging over USB_CDC. I am not a coder so I may be wrong.

[Fabian-Schmidt]

Can you please test the following external component:

external_components:
  - source: github://Fabian-Schmidt/esphome-truma_inetbox
    components: ["truma_inetbox"]

The uart component was needed in the first release and the changes have been made upstream in esphome. I require it sometimes for local testing things and might remove it in the future.

Thanks Fabian, now it compiles. Will now try if I can get some logs from my Alde 3020.
