BLEProxy does not discover any new devices

nymare · October 24, 2022, 12:20pm

Hi all,

this is a continuation of ESP32-C3 deplyoment: ESP32-C3 Bluetooth Proxy invalid header: 0xffffffff - #3 by nymare

BLE-Proxy seems to work (see logs below), but i don’t get any new devices Discovered.
Maybe i need to Discover devices via standard BLE and then only use Proxy to communicate with them later on? Two thermometers i’ve Discovered via standard BLE now work flawlessly via BLE Proxy. I did delete original LWMMM… BLE Discovered device integrations before they were flashed.

Let me share some more findings. I am using only this in ESPHome (removed BLE Tracker):

bluetooth_proxy:
active: true

I will try to add ATC thermometers i’ve flashed manually.
Flashing link: Telink Flasher
ESPHome ATC Thermometer sensor instructions: Xiaomi Mijia BLE Sensors — ESPHome

Verbose logs show ATC is visible, but does not popup as Discovered in HomeAssistant:

I only use Proxies. Maybe C3 issues

You need ad BTHome or xiaomi ble integration. If not autodiscovered

nymare · October 25, 2022, 1:51pm

Thanks Nikito7, your pointers were good.

I already had XIAOMI BLE, but it did not find any thermometers. I then focused on your BTHome advice and that worked.

For anyone else who needs help, this are the steps:

Download latest ATC FW for BTHome compatible communication: GitHub - pvvx/ATC_MiThermometer: Custom firmware for the Xiaomi Thermometers and Telink Flasher via USB to Serial converter
Connect and Flash thermometer over this website: Telink OTA
Once flashed you can then change parameters (i only changed Advertising type to BTHome protocol): Telink Flasher v4.4
Add BTHome Integration and in my case devices reachable through proxy were already waiting to be added into this integration BTHome - Home Assistant

Still not sure why Xiaomi BLE worked originally for first two flashed thermometers, but i don’t care as BTHome works well.

lorcott · October 25, 2022, 3:06pm

My BLE found my thermometer. It shows as entities in ESPHOME but the results read “UNKNOWN”.

nymare · October 25, 2022, 4:03pm

Scott, you mean you only get 1 entity? As this is what i got when i had FW that could push BLE out, but HomeAssistant was not able to read data. Changing FW setting to supported communication adds new entities.

In case you get entities, but not updated it means it is not receiving the device BLE messages.

Do you use BLE Proxy? As one useful feature is Verbose logging

lorcott · October 25, 2022, 5:12pm

I setup via ESPHOME. What is FW? Screen Shot 2022-10-25 at 1.10.44 PM

nymare · October 25, 2022, 5:41pm

I thought you have Xiaomi thermometer and then need to upload custom FW: Esphome Tutorial: for 4$ monitor your home temperature with esp32 and xiaomi mijia ·

Can you share your ESPHome code? As it looks like you don have BLE, but ESP32 based thermomether.

ok…some progress…

lorcott · October 25, 2022, 11:45pm

I have stats but no temp or humidity

nikito7 · October 25, 2022, 11:53pm

see pvvx stuff above.

Only work with Mi adv ou BThome adverts type

nikito7 · October 25, 2022, 11:55pm

Pvvx site:

Ha:

Blacky · October 26, 2022, 11:05am

@lorcott Just wait it takes some time to load.

@nikito7 BTHome has a lot decimal points. I don’t like BTHome because of that, and rather use the xiaomi or the Mijia advertising. I have 13 sensors all working well and battery life is good (over 1 year)

I also disable the voltage as it not required and it is just more data

lorcott · October 26, 2022, 12:37pm

thx…now when I’m ready to add another thermo, do I need to change the MAC address in ESPHOME? FYI I just copied that MAC address from a setup sample so I don’t know where it points.

nikito7 · October 26, 2022, 12:44pm

You just need Bluetooth proxy

lorcott · October 26, 2022, 1:55pm

currently my ESPHOME has

esp32_ble_tracker:
  scan_parameters:
    active: true

bluetooth_proxy:

esp32:
  board: esp32dev
  framework:
    type: arduino

# Enable logging

# Enable Home Assistant API
api:

ota:
sensor:
  - platform: atc_mithermometer
    mac_address: "A4:C1:38:B1:CD:7F"
    temperature:
      name: "A Temperature"

Do I not need the other stuff???

nikito7 · October 26, 2022, 2:31pm

You dont need:

sensor:
  - platform: atc_mithermometer

After only in HA

BTHome
xiaomi ble
