Web Bluetooth Support in Firefox for ESP32 BLE Use Cases

Making moves

Hi everyone, I’m working on an ESP32 project that broadcasts sensor data (temperature, motion, etc.) over BLE GATT and I’d like to access it via a browser interface ideally using Web Bluetooth. I built an ESP32 BLE GATT server following tutorial, which helped me set up services and characteristic notifications:

I’ve also been reading MDN’s Web Bluetooth security best practices and testing sample code for characteristic subscriptions in Chrome. However, I’m unsure how Firefox currently compares how reliable is it for Web Bluetooth pairing and notifications with ESP32 devices?
