Can not connect an iOS to an Android device

[dittmarconsulting]

Love both libraries (Rusel's and yours)

Everything works find on Android but I have issues connecting to an Android device. To be safe I have paired both devices manually beforehand.

I have the UUID (i.e. '00001103-0000-1000-8000-00805f9b34fb') but I'm not able to connect to the Android device running your lib on an iOS device (iPhone 8, iOS12, Xcode10)

In essence I'm running the following function

import BluetoothSerial from 'react-native-bluetooth-serial'

const connect = async (btId) => {
    return await BluetoothSerial.connect('00001103-0000-1000-8000-00805f9b34fb')
}

Any idea what the problem might be? I've had a look at the Objective-C code but everything looks fine to me.

Here the log:

2018-10-03 12:34:50.343835+1000 btTestApp[728:288833] disconnect

By the way, both devices use classic BT NOT BLE

Many thanks in advance.

Have you tried using BluetoothSerialExample? There is a function to connect to device:

connect (device) {
    BluetoothSerial.connect(device.id)
    .then((res) => {
      Toast.showShortBottom(`Connected to device ${device.name}`)
    })
    .catch((err) => Toast.showShortBottom(err.message))
}

Using this code you can check with .catch() if there is a problem with connection.

On the other hand, in the original repository there is not an issue related with yours, so that I expect it works, nevertheless I cannot assure you that this library works as expected on IOS, because I'm not test it yet on IOS. I'm going to test it on IOS soon, so please let me know if you have any progress.

Thanks.
