FlorianandClaude Opus 4.8 268b879239 [BT] Bump NimBLE-Arduino 2.3.2 -> 2.5.0 to fix BLE scan regression on Arduino core 3.3.7+ (#2333 )

The esp32_platform 55.03.39 bump (#2329) ships Arduino-ESP32 core >=3.3.7,
whose NimBLE integration enables mesh scan-filtering. NimBLE-Arduino 2.3.2
(pinned since 2025-06-28) handles this incorrectly and stops reporting
advertisements on scan restart, so continuously-scanning gateways (e.g. the
Theengs Bridge) decode nothing.

Upstream fix: h2zero/NimBLE-Arduino 98548470f "[Bugfix] Scan duplicate filter
not resetting on scan restart" (released in 2.3.9). Bumping to the latest 2.5.0
also picks up the Arduino 3.3.7 "controller invalid state" init fix (2.3.8/2.3.9)
and a scan-response timer for long-duration scans.

HIL-validated on a Theengs Bridge v11 with esp32_platform 55.03.39:
  - NimBLE 2.3.2: BLE decode 0/3
  - NimBLE 2.5.0: BLE decode 3/3, reachability 2/2, builds clean

Products powered by OpenMQTTGateway

Theengs Bridge, Bluetooth gateway (BLE) with external antenna

Theengs bridge is a powerfull BLE to MQTT gateway for over 100 sensors. Equipped with an Ethernet port, and external antenna, ensuring an enhanced range for your BLE sensors. It supports also WiFi connectivity.

Theengs Plug, Bluetooth gateway (BLE) gateway and Smart Plug

Theengs plug brings the following features:

BLE to MQTT gateway, tens of Bluetooth devices supported thanks to Theengs Decoder library. The plug uses an ESP32 acting as a BLE to Wifi gateway to scan, decode and forward the data of the nearby sensors,

Energy consumption monitoring,
Device tracker,
Presence detection (beta),
Local connectivity first.

Support the project by purchasing the Theengs bridge or the Theengs plug
