Hello
Can you share the exact code you're working with? Where's this updateReader error originating from?

#

Are you seeing that when you call connectReader ?

vestal crest Apr 7, 2025, 7:21 PM

#

yes when I call connect reader

#

seems to be coming from a stripe module in the logcat - "StripeTerminal"

#

What are you passing as your SimulatorConfiguration?

vestal crest Apr 7, 2025, 7:24 PM

#

I was setting discoveryconfig to (isSimulated= true), but haven't passed a specific simulator config

#

like this

#

Hmm I meant when you call connectReader, what are you passing in as the second parameter?

#

The issue seems to be with Connection and not Discovery

fun connectToReader(
reader: Reader,
locationId: String = DEFAULT_LOCATION_ID,
onSuccess: (Reader) -> Unit,
onFailure: (TerminalException) -> Unit
) {
try {
// Check if already connected to this reader
if (currentReader != null && currentReader?.id == reader.id) {
// Already connected to this reader, just call the success callback
onSuccess(currentReader!!)
return
}

        // Not connected or connected to a different reader
        val config = createConnectionConfig(locationId)

        terminal?.connectReader(
            reader,
            config,
            createReaderCallback(onSuccess, onFailure)
        )
    } catch (e: Exception) {
        handleConnectionError(e, onFailure)
    }
}

private fun createConnectionConfig(locationId: String): ConnectionConfiguration {
    return ConnectionConfiguration.TapToPayConnectionConfiguration(
        locationId = locationId,
        autoReconnectOnUnexpectedDisconnect = true,
        tapToPayReaderListener = createTapToPayListener()
    )
}

#

It's createConnectionConfig isn't it?!

cyan forge Apr 7, 2025, 7:28 PM

#

Yup
Hmm I don't see anything that might trigger an update on the simulated reader 🤔

vestal crest Apr 7, 2025, 7:30 PM

#

thanks so much for your help

#

sometimes being a solo dev is exhausting

cyan forge Apr 7, 2025, 7:31 PM

#

Are you on the latest version of the SDK?

vestal crest Apr 7, 2025, 7:31 PM

#

I'll have to check, haven't updated for a while

cyan forge Apr 7, 2025, 7:34 PM

#

Gotcha. Can you try using the latest SDK if you don't currently have that set up yet?

Also, just to confirm -- there arent' any other places where your code calls Terminal.getInstance().simulatorConfiguration or anything similar -- correct?

vestal crest Apr 7, 2025, 7:35 PM

#

Just moving from 4.1 to 4.3
Yes you're right no other places that call simulatorConfiguration

cyan forge Apr 7, 2025, 7:46 PM

#

Hmm I don't have a way to reproduce this error at the moment. Are you able to test this on an actual device to see if you're able to test with non-simulated device?
