Webview+BLE application IOS/Android

Hello

I am ready to get started. The task is clear and normal for a production MVP.

I will create a cross-platform application for iOS 14+ and Android 7+ where the main interface opens inside a WebView, and device control works via BLE even without Wi-Fi.

I suggest using the Capacitor or React Native stack. If you already have a web interface and it is important to quickly and accurately integrate it with a JS ↔ native bridge, then Capacitor is usually the fastest and most stable option.

What I will do in terms of functionality:
… An application with a WebView that loads your URL or local build, with support for cookies, JS, and responsive design.
A BLE module that scans, connects to the required device, pairs if necessary, and exchanges data through your GATT characteristics.
A JS to Native bridge so that the web interface can call functions like connect, scan, sendCommand, readStatus, and receive responses back in JS in the form of promises or events.
Error and status handling so that it is always clear in the web interface what is happening: no Bluetooth, no permissions, device not found, connection lost, timeout.

As a result, you will receive:
An application that works as a shell over your web UI and additionally provides standalone BLE control.
Compiled builds and source code.
A short documentation on the bridge and examples of calls from JS.

To estimate the timeline and start immediately, please send:
BLE specification, GATT services, characteristics, and command format.
What logic is in the web, what specific actions should go to BLE.
Is the web interface a URL or will you provide a build that needs to be placed locally?
Is a background connection needed or is it sufficient to work only when the application is open?

I can start immediately after receiving the BLE documentation and access to the web interface.

Hello! I am ready to implement your device management application. I have experience working with BLE and integrating web interfaces into mobile applications. I will use Flutter or React Native for stable communication with the device. I will set up command transmission from your web interface to the native BLE module via JavaScriptChannel to ensure seamless control. I will implement correct scanning, connection, and data exchange according to your GATT protocol, taking into account the specifics of permissions on Android and iOS.

Can we discuss the details of your BLE protocol and command structure? My portfolio: Freelancehunt
