Hi @darshitpolaris,
I'm trying to connect with the device but I'm not getting the Bluetooth device list in onMessageReceived method. can you please attach some working examples?

Hii @dhruvanb

Have you added any Bluetooth permission in the android manifest
for below android 11, you need to add

    <uses-permission android:name="android.permission.BLUETOOTH" />  
    <uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />  
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>  
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

and for android 12 you need to add this permission for bluetooth scan

    <uses-permission android:name="android.permission.BLUETOOTH_SCAN"/>
   <uses-permission android:name="android.permission.BLUETOOTH_CONNECT"/>
   
   for ios,
   add this permission in info.plist
      <key>NSBluetoothAlwaysUsageDescription</key>  
    <string>Need BLE permission</string>  
    <key>NSBluetoothPeripheralUsageDescription</key>  
    <string>Need BLE permission</string>  
    <key>NSLocationAlwaysAndWhenInUseUsageDescription</key>  
    <string>Need Location permission</string>  
    <key>NSLocationAlwaysUsageDescription</key>  
    <string>Need Location permission</string>  
    <key>NSLocationWhenInUseUsageDescription</key>  
    <string>Need Location permission</string>

Hi @darshitpolaris,
yes, I have added it and modified the code as per my requirement.

[darshitpolaris]

@dhruvanb Are you getting Bluetooth list??

[dhruvanb]

@darshitpolaris please check OP mode in native code by setting setOpMode method.

[darshitpolaris]

@dhruvanb I'm not getting what you say.
