Connect to BLE devices - Bluetooth Low Energy (BLE) in Flutter

#flutter #ble #bluetooth
Hello everyone! In this Flutter tutorial, we will delve into the seamless integration of a BLE Scanner + connecting to BLE devices in Flutter application. Get ready to embark on this journey as we harness the power of the "flutter_blue" package, a vital component in our exploration of Bluetooth Low Energy (BLE) technology. Let's dive right in!

I would appreciate it if you could please make a video about sending text to a rasperi device after establishing the connection. Thank you for your interest.

[@ThaZeroCoder-tt5di]

Very nice tutorial sir😊

Great content, I have doubt that flutter blue plus is the latest version and why are you using flutter blue. When I checked it has over 500 plus open issues.

[@manasareddy6183]

Please release the video of extension of this video that after establishing the connection how can we read and services...

[@dankanezuu]

bro, how to keep the device connected? i tried autoconnect, i tried scan and connect every 10 sec, i tried to add the mac of the device in the code, but still doesnt work

[@manasareddy6183]

I have a doubt that when the user click on the scan button it's displaying devices if we want the thing that not the ip addresses of that device...the name of the device should show like when We try to connect the Bluetooth in our phone we are able to see the names right not the ip addresses....

for (ScanResult result in scanResult) { if (!_devices.contains(result.device) && _isValidDeviceName(result.device.name)) { setState(() { _devices.add(result.device); }); } /*if (!_devices.contains(result.device)) { setState(() { _devices.add(result.device); }); }*/ } bool _isValidDeviceName(String? name) { if (name == null || name.isEmpty) { return false; } // Check if the device name starts with a numeric character return !RegExp(r'^[0-9]').hasMatch(name); } i had the same issue above code resolve your problems.

Pub failed to delete entry because it was in use by another process. This may be caused by a virus scanner or having a file in the directory open in another application. When running pubspec.yaml like in the video I get this error

[@SaurabhNanda-he8jt]

[@ProtoCodersPoint]

Are you using pure BLE device ?? Earphone, laptop are not BLE devices Make sure you are using Bluetooth low energy devices for example IOT DEVICES

Please Give solution for error: A problem occurred configuring project ':flutter_blue'. >Could not get unknown property 'source' for generate-proto-generateDebugProto of typr org.gradle.api.internal.file.DefaultSourceDirectorySet.
