26.1.5

What's Changed

ESP-IDF 5.5.2 shipped with a regression in the Bluetooth controller binary that causes BLE scanning to silently stop after hours or days of uptime. After the failure, the controller is dead and only a full device reboot recovers it. This has been broken for a large number of users since the 26.1.1 update.

This release applies a patched BT controller firmware on top of ESP-IDF 5.5.2 that includes the upstream fix from Espressif (esp32-bt-lib commit 06dc4667):

• fix(ble): Fixed BLE enable scan timeout
• fix(ble): fixed crash in btdm_controller_task

If you were previously working around this by pinning to ESP-IDF 5.5.1, you can remove that pin and use release: "260206" instead:

esp32:
  framework:
    type: esp-idf
    version: 5.5.2
    release: "260206"

Note: This is a temporary pin. Once ESP-IDF 5.5.3 ships with the fix included, you should remove the release line to pick up the default version.

Full Changelog: 26.1.1...26.1.5

26.1.1

What's Changed

Update ESPHome to 2026.1.1 with WiFi Roaming support https://esphome.io/changelog/2026.1.0/

Full Changelog: 25.12.6...26.1.1

25.12.6

What's Changed

Ethernet-based proxies now use ESPHome's default scan parameters. The previous 1100ms interval/window settings predate current ESPHome recommendations and can increase CPU usage or cause resets due to overheating on some devices.

Users who prefer custom scan timing can take control of their device in the ESPHome dashboard and configure https://esphome.io/components/esp32_ble_tracker/ to their preference.

• Remove aggressive scan parameters from PoE proxies by @bdraco in #151

Full Changelog: 25.12.4...25.12.6

25.12.4

What's Changed

Ethernet-based proxies can now connect to and control 4 Bluetooth devices simultaneously (up from 3). This is possible thanks to significant memory savings and low-latency BLE event processing in recent ESPHome versions. WiFi proxies remain at 3 connections as they share airtime with BLE.

• Increase connection slots to 4 for ethernet proxies by @bdraco in #145
