Battling to troubleshoot BT Proxy

ESPHome
1

I have one BT Proxy that is working.

I installed another one using:

esphome:
  name: bt-proxy-office
  friendly_name: BT-Proxy-Office
  platformio_options:
    board_build.mcu: esp32c3
    board_build.variant: esp32c3  
# added the line below to prevent bootloops when flashing modern bin via serial
    board_build.flash_mode: dio     

esp32:
  variant: ESP32C3
  board: esp32-c3-devkitm-1
  framework:
    type: esp-idf
    sdkconfig_options:
      CONFIG_BT_BLE_50_FEATURES_SUPPORTED: y
      CONFIG_BT_BLE_42_FEATURES_SUPPORTED: y
      CONFIG_ESP_TASK_WDT_TIMEOUT_S: "10"  

# Enable logging
logger:

# Enable Home Assistant API
api:
  encryption:
    key: !secret ekey-bt-proxy-office

ota:
  - platform: esphome
    password: !secret ota-bt-proxy-office

wifi:
  ssid: !secret wifi_ssid
  password: !secret wifi_password

esp32_ble_tracker:
  scan_parameters:
    interval: 1100ms
    window: 1100ms
    active: true

bluetooth_proxy:
  active: true

It uploaded fine and is online in ESPHome.

When I go look at the system logs however, I get:
bt-proxy-office @ xx.xx.xx.xx: Connection error occurred: [Errno 104] Connection reset by peer.

This said, the ESPHome logs show everything as fine.

Further, “Bermuda BLE Trilateration” does not seem to see it.

Remove the following two lines from your config.

window: 1100
interval: 1100

The above should only be added when wired, not via Wi-Fi, this is in the documentation but easily missed.

Brilliant @EBME2 many thanks, that did it as well as fix the incorrect distances I was getting.
