cheasonxie commented 4 months ago

lightblue can found this paired device, Its source code can be refered to.

cheasonxie commented 4 months ago

It's ok after I add my device's UUID to uuid array in file FlutterBluePlusPlugin.m under "getSystemDevices" method, like this:

            // Cannot pass blank UUID list for security reasons.
            // Assume all devices have the Generic Access service 0x1800
            CBUUID* gasUuid = [CBUUID UUIDWithString:@"1800"];
             CBUUID* gasUuid1 = [CBUUID UUIDWithString:@"ffe0"];
             CBUUID* gasUuid2 = [CBUUID UUIDWithString:@"69400001-b5a3-f393-e0a9-e50e24dcca99"];

             // this returns devices connected by *any* app
             NSArray *periphs = [self.centralManager retrieveConnectedPeripheralsWithServices:@[gasUuid, gasUuid1, gasUuid2]];
burekas7 commented 3 months ago

@cheasonxie I have the same issue. This is the only solution? How do I know what is the UUID?

cheasonxie commented 3 months ago

@burekas7 hi, I don't know if there is any other solution. I am not familiar with IOS development. you can use bluetooth debug app such as nRF Connect or LightBlue to find your device's UUID
