Reader not discovered in handoff mode on S700 Devkit

[rlfrahm]

Describe the bug

The following versions cause discoverReaders to never return a reader to connect to:

implementation("com.stripe:stripeterminal-core:3.8.0")
implementation("com.stripe:stripeterminal-handoffclient:3.8.0")

While 3.7.0 seems to work fine:

implementation("com.stripe:stripeterminal-core:3.7.0")
implementation("com.stripe:stripeterminal-handoffclient:3.7.0")

I also have this problem while using 0.0.1-beta.20 of this package:

...
"@stripe/stripe-terminal-react-native": "0.0.1-beta.20"
...

While 0.0.1-beta.19 works fine.

I'm using this issue as reference for how to setup handoff mode.

To Reproduce Steps to reproduce the behavior:

1. Install 0.0.1-beta.20 and build example-app
2. Deploy example-app through Stripe on physical S700 Devkit
3. Try to discover readers in handoff discovery mode
4. No readers discovered

Expected behavior It should discover readers in the latest version.

Updated my original description to change the Android package versions to 3.7.0 as that is the latest version that I can get to work.

I having this issue even using a bluetooth reader.

@thelight413 are you using an S700 device or something else?

[thelight413]

I'm using my android phone and an android tablet. I was also having issues connecting to the reader even if it was discovered. But only on a fresh install, not when I restart the app.

Make sure that your connection token is not cached from your api. The provider makes several calls for a connection token and they all have to be new tokens. I was having a similar issue and that was the cause.I also cannot use beta20 of this package as the reader will not be discovered when on a physical device and not in simulated mode.

@rlfrahm I even recreated the issue on the example app. I am using render as a backend.

I had the same intermittent troubles when getting started. It wasn't until I reached out to Stripe on their Discord that it finally started working at least partially. I'd recommend opening a ticket there: https://discord.com/invite/stripe

@rlfrahm for your issue, did you wait till the sdk initialized?

Hello, I have a similar issue using the Java/Kotlin SDK.

I get the following error message with the android sample app:

discoveryCallback onFailure
com.stripe.stripeterminal.external.models.TerminalException: RPC application error INVALID_REQUEST with message Invalid device_type: must be one of bbpos_wisepad3, stripe_m2, stripe_s700, bbpos_chipper2x, bbpos_wisepos_e, verifone_P400, simulated_wisepos_e, or mobile_phone_reader

    at android.os.Binder.execTransactInternal(Binder.java:1021)
    at android.os.Binder.execTransact(Binder.java:994)

The error message seems to suggest that stripe_s700 are accepted for Handoff dicovery, but maybe not stripe_s700_devkit ?

I've confirmed that with Stripe staff that the S700 devices should be in handoff mode and it's working for me now after downgrading versions. Are you by chance using production api keys or something? DevKit's only work in test mode.
