* update build to use python 3.14 with platformio 6.1.19
* Update esp32-arduino-lib-builder to v1.5
* [CI] Fix call8 link overflow on large Xtensa builds (IDF 5.5.4)
The 55.03.39 / IDF 5.5.4 bump enlarges the precompiled libs enough that
large Xtensa images (esp32 / esp32s3) overflow the call8 reach and fail to
link with "dangerous relocation: call8: call target out of range".
-mlongcalls (which makes calls linker-relaxable) is injected by
esp32-arduino-libs into the framework compile but NOT into lib_deps
(NimBLE-Arduino, ArduinoJson) or project sources.
Add a project pre: extra_script (scripts/add_mlongcalls.py) that applies
-mlongcalls to CCFLAGS/ASFLAGS, gated on the Xtensa MCUs (RISC-V c3 has no
call8 and rejects the flag). Wired into [env]; the four esp32dev-*pilight*
envs that set their own extra_scripts list it explicitly too, since
PlatformIO replaces rather than merges extra_scripts.
Also bump esp32-arduino-libs 0.1.5 -> 0.1.6, which restores the
framework-side -mdisable-hardware-atomics / -fno-builtin-* flags that 0.1.5
dropped under IDF 5.5.4 (separate from the lib_deps call8 issue).
Verified clean (0 call8): esp32dev-all-test, esp32dev-ble, theengs-bridge,
theengs-plug, esp32dev-pilight (+cc1101); esp32c3 unaffected.

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,
- Smart plug that can be controlled remotely,
- Energy consumption monitoring,
- Device tracker,
- Presence detection (beta),
- Local connectivity first.
Support the project by purchasing the Theengs bridge or the Theengs plug
