Good question. Looking in to this and will get back to you. For some extra context, what reader type are you using here? I don't think that will change the API shape but sometimes that info can still be helpful

Thank you! Card Reader M2

Still looking. Out of curiosity, are the devices otherwise connecting and able to make payments?
tacit tree
Yes, is working correctly. Also I can see logs with the software version after the connection.

Hi there - taking over for Pompey, who has to go
I'm not super familiar with the Terminal android SDK - let me see if I can find a colleague who knows more about this.

Hi! I believe it's possible to use the onConnectionStatusChange callback function to get an early software version.
After the status is CONNECTED
fervent bear
Does this happen with all your readers?
tacit tree
I just debugged in this callback and I can see the software version in this case
fervent bear
That's to say you think that's the way you're supposed to access that property?
I assumed you are talking about the ReaderCallback in Terminal.getInstance().connectReader()
tacit tree
The problem is that in this method (onSuccess callback) the software version is "unknown", but in override fun onConnectionStatusChange(status: ConnectionStatus) when the status is CONNECTED the version appear with correct value:
So I assume now that this is the correct moment to get this information without calling the terminal from my code

hi! fyi i'm jumping in to help out here
i can't remember off the top of my head when this becomes available but it sounds like you're on the right track. let me look at my own test app to double check some things
hmmmmm when i run my test app in a simulator at least, i am seeing the software version
are you using a similator or an actual device?
here's all i'm doing in my app
Terminal.getInstance().connectReader(
reader,
connectionConfig,
onConnectReader()
)
}
...
private fun onConnectReader(): ReaderCallback {
return object : ReaderCallback {
override fun onSuccess(reader: Reader) {
val readerEmitSuccess = _connectReaderFlow.tryEmit(reader)
val connectionInProgressEmitSuccess = _connectInProgressFlow.tryEmit(false)
val errorEmitSuccess = _connectErrorFlow.tryEmit(null)
if (!readerEmitSuccess || !connectionInProgressEmitSuccess || !errorEmitSuccess) {
Log.w(TAG, "Failed to emit reader to flow, buffer might be full or no active collectors.")
} else {
Log.d(TAG, "Reader emitted to flow.")
Log.d(TAG, "READER SOFTWARE VERSION")
Log.d(TAG, reader.softwareVersion)
}
}
...```and then i see this in my logs:
READER SOFTWARE VERSION
1.00.03.32-SZZZ_Generic_v36-580001```can you try with a simulated device real quick? i can grab my actual device and test there too but it might take me a bit
tacit tree
which SDK version are you using?
kind matrix
good question, lemme double check
this app is running 4.7.2, and yours?
i can try on a different version if needed
also working on getting my physical test device set up now
tacit tree
4.6.0
kind matrix
ok yep, i'm getting the same thing on my physical device
tacit tree
you have the same delay?
kind matrix
let me see if i can test on 4.6.0 without breaking things
no sorry, i am seeing it log as soon as the onConnectReader callback is hit
tacit tree
ok, ok
kind matrix
let me try on 4.6.0 ⏱️
hmm yep it's working for me on 4.6.0 too
can you share your code where you're calling Terminal.getInstance().connectReader as well as where you define the callback?
also can you confirm if you'll be able to test it out with a simulated terminal device instead of the actual M2? i'm curious if the results will be different at all
kind matrix
it's in the discovery config, 1 sec
this doc walks you through it, but it should be a 1 line change
here's what it looks like in my app. for yours you can literally just add isSimulated = true to your BluetoothDiscoveryConfiguration
timeout = timeout,
isSimulated = simulated
)
...
discoverCancelable = Terminal.getInstance().discoverReaders(
config,
this,
onDiscoveryComplete()
)```what happens if you just log out reader.softwareVersion in your onSucess?
tacit tree
with simulation is working correctly
tacit tree
not, just one
kind matrix
i wonder if there's something about the device itself or the softwareVersion it's on that's resulting in it showing null
is it fully updated?
kind matrix
where are you actually logging out the reader.softwareVersion in your code? i don't see it in the ReaderCallback
tacit tree
I added the log after I sent you the code
override fun onSuccess(connectedReader: Reader) {
connectivityLogStatus("[Connection] connectReader success: ${reader.serialNumber}")
Log.e("TAG", "${reader.softwareVersion}")
val readerModel =
StripeReaderModel.fromReader(reader = reader, connectionType = connectionType)
val response = StripeReaderResponseModel(reader = readerModel)
cardReaderManager.callbackResponse(CB_CONNECT_READER_RESULT, response.toJson() ?: "")
}
here I have the log
kind matrix
gotcha, and when you run that exact code with the actual M2 reader you're still seeing unknown in the reader.softwareVersion line?
tacit tree
exactly
I think I will use the onConnectionStatusChange callback to manage this information
is ok, is just to show the version
kind matrix
yeah, if that's working for you it should be fine to rely on that
tacit tree
I will try tomorrow a bit more
kind matrix

Now I have curiosity because is working in your enviroment 😅
