🔵 BLE Gateway - Kontrol ESP32 Tanpa WiFi

BLE Gateway adalah fitur di Chat AIoT yang mengubah smartphone menjadi bridge antara internet dan perangkat ESP32 via Bluetooth Low Energy. ESP32 tidak perlu terhubung ke WiFi sama sekali!

Cara Kerja BLE Gateway

• ESP32 jalan sebagai BLE server (Bluetooth on, WiFi mati)
• Smartphone connect ke ESP32 via Bluetooth
• Perintah dari internet diterima smartphone → diteruskan ke ESP32 via BLE
• ESP32 balas via BLE → smartphone kirim ke internet

Kelebihan vs WiFi MQTT

• ⚡ ESP32 lebih hemat daya — WiFi mati, BLE konsumsi ~10mA
• 🏠 Bisa dipakai di area tanpa WiFi — kebun, garasi, outdoor
• 📱 Kontrol langsung — tetap bisa dipakai walau internet mati

Setup BLE Gateway

• Upload firmware BLE ke ESP32 via Arduino IDE
• Buka Chat AIoT di smartphone Android
• Pergi ke IoT Devices → Tambah device → pilih ESP32 BLE
• Scan perangkat Bluetooth, pilih ESP32 lo
• Selesai! ESP32 sekarang online via smartphone
