QuectelEC200U@1.5.0

1.5.0 - 2025-09-30
ESP32 standardization: all examples now use Serial2 with default pins EC200U_RX=18, EC200U_TX=17 and PW_KEY=10 via a new shared header src/EC200U_ESP32_Config.h (includes EC200U_powerOn helper).
Examples updated: HTTP, HTTPS, MQTT, NTP Sync, GNSS, FTP, Audio Setup, SMS, TCP, TTS, Voice Call, Bluetooth_and_WiFi switched to Serial2 config and cleaned legacy includes.
Docs: README updated to show the circuit image, corrected repository link, and added “More information” link to the ESP32‑S3 with EC200U reference project.
Breaking changes: none; library API unchanged. Non‑ESP32 boards continue to use SoftwareSerial paths.
