upon debugging using Xcode, it seems that the connectLocalMobileReader method is not resolving, causing the process to hang.

       const connectMobileReader = async (reader: any, onConnect?: any) => {
          console.log('Connecting to mobile reader:', reader);

        const { error } = await connectLocalMobileReader({
              locationId: location.data?.data.stripe_id,
              reader: reader || (mobileReader as Reader.Type),
        });

        if (error) {
              log({
                    message: 'Error connecting to mobile reader',
                    error,
              });
        }
  };

I've test on my end on an iOS 18 device using the dev-app(https://github.com/stripe/stripe-terminal-react-native/tree/main/dev-app) and unfortunately it works from connect to successful payment so I'm a bit confuse about the issue you mentioned. It seems related to connect? and what is the error log you get? It seems no Error connecting to mobile reader according to your code. And in your log it also contains BT connection related stuff, what is your steps? Thank you in advance.

Well there isn't any error from the connectLocalMobileReader, its just gets stuck at that(connectLocalMobileReader) method. However the issue is not 100%, it occurs randomly and works the other times. with our testing on iOS 17 the app behaves perfectly fine, implicating that the issue is only on >=iOS 18.0

The bluetooth related logs in the ss is from the terminal reader scan I believe. the steps include:

1. disconnect any connected terminal reader
2. cancel any pending readers search
3. call the discover method for localMobileReader
4. connect to the discovered reader

Sorry it take a while to test which part the issue is and also discuss internally with different people, so far we still not able to reproduce by just changing connection method. Would it be possible from your end to test the same condition using our dev-app to see if it still happened? And the same time we'll also try to see if there's other possibility to this issue. Thanks.

[manashathparia]

yes sure @tim-lin-bbpos

Looking at our logs for the device in screenshots (serial fa8572a6cf7ab50955f7c6837b8ef781574577fe8ebd09b2cd1471d14c62aee5) the main error we see is Already_connected_to_a_reader._Disconnect_from_the_reader,_or_power_it_off_before_trying_again. Just want to rule out you are aware of that and are handling it.

[manashathparia]

yes @nazli-stripe I am aware of it and it is handled in the function

[manashathparia]

@tim-lin-bbpos is there any update on this issue?

[nazli-stripe]
