Integrating Bluetooth Low Energy (BLE) into mobile apps is essential for many modern applications, from fitness trackers to smart home devices. I recently built a fully functional BLE app using FlutterFlow for IoT devices and would like to share my experience to help others in the community as I noticed that lots of FlutterFlow developers are struggling with implementing it.

Creating a BLE app in FlutterFlow involves several challenges:
1. 𝐇𝐚𝐧𝐝𝐥𝐢𝐧𝐠 𝐏𝐞𝐫𝐦𝐢𝐬𝐬𝐢𝐨𝐧𝐬: Properly requesting and managing permissions like location and Bluetooth access is crucial especially in Android 12 and above.
2. 𝐌𝐚𝐧𝐚𝐠𝐢𝐧𝐠 𝐁𝐋𝐄 𝐂𝐨𝐧𝐧𝐞𝐜𝐭𝐢𝐨𝐧𝐬: Establishing and maintaining stable BLE connections can be complex.
3. 𝐄𝐧𝐬𝐮𝐫𝐢𝐧𝐠 𝐂𝐨𝐦𝐩𝐚𝐭𝐢𝐛𝐢𝐥𝐢𝐭𝐲: Ensuring the app works seamlessly across various Android devices requires extensive testing.

To tackle these challenges, I followed these steps:
1. 𝐏𝐞𝐫𝐦𝐢𝐬𝐬𝐢𝐨𝐧 𝐌𝐚𝐧𝐚𝐠𝐞𝐦𝐞𝐧𝐭: I used FlutterFlow’s custom actions to request and confirm permissions effectively.
2. 𝐁𝐋𝐄 𝐈𝐧𝐭𝐞𝐠𝐫𝐚𝐭𝐢𝐨𝐧: Leveraging the FlutterBluePlus plugin, I integrated BLE functionality with some custom coding.
3. 𝐓𝐡𝐨𝐫𝐨𝐮𝐠𝐡 𝐓𝐞𝐬𝐭𝐢𝐧𝐠: I conducted rigorous testing across multiple Android devices to ensure compatibility.

This is a demo/test app for a project I am about starting which will have Bluetooth functionality.
