V/Kable/Observation: 39d79ee2-1ef7-0ac0-b8be-4c500c92cbf9 Suppressed failure: com.juul.kable.NotReadyException

[travis]

Can you provide additional logs, please?

[Cristian MG]

Yes, thats the console in xcode is returning

notreadybug

[Cristian MG]

I'm developing a library in kotlin native to be able to access and parse FTMS ble devices that is an standard in some industries to access ble devices related to the fitness

[Cristian MG]

To this purpose i'm making a little wrapper with this library that I starting with the 0.22 version, but unfortunately in this version in ios is not working for me, the code is failing not delivering the results of characteristics info with no reasons, then I decided to migrate to version 0.24, facing this problem since then

[travis]

It looks like a bug. I can investigate more later this week.
Are you able to file a bug, or would you like me to?

[Cristian MG]

Wait please, I'm testing in the 0.23 version to check if this error is a regression or not

[Cristian MG]

Ok the error is a regression I have no doubts

[Cristian MG]

about this

[travis]

Issue doesn’t happen w/ 0.23.0?

[Cristian MG]

Nop, I have another weird behavior I think is not related with this problem

[travis]

Thanks for testing 0.23.0! Knowing it is a regression is very helpful.

[Cristian MG]

Log working

bug_not_receiving_collect

[Cristian MG]

Your welcome

[Cristian MG]

Then, closed this topic, any idea that why 0.23 version is not emitting in collect the result althought, I can see the results of notify in console? Like you can see in the last log I sended it

[travis]

Can you share a code snippet?

[Cristian MG]

Ios code or kotlin code?

[travis]

Whatever code is calling collect on the observe.

[Cristian MG]

fun treadmillData(
    connection: DeviceConnection
): Flow<TreadmillData> =

    connection.getConnection().observe(
        characteristicOf(
            FitFlowServices.FitnessMachine.uuid,
            FtmsCharacteristic.TreadmillData.uuid
        )
    ).map {
        TreadmillDataFlags.byteToModel(it)
    }.runningReduce { accumulator, value ->
        accumulator + value
    }.map {
        TreadmillData(it)
    }

[Cristian MG]

This is the code, this code is working fine in Android

[travis]

Can you add an onEach after the observe (and before the first map) to confirm you are not getting emissions?

[travis]

Sorry, I’m heading to bed. I can try to find time tomorrow, or later this week, to help you some more.

[Cristian MG]

Ok thanks so much, let's keep in touch

[travis]

Created https://github.com/JuulLabs/kable/issues/500 to track.

[travis]

I'm not able to repro your issue with devices I have. Is the device you're connecting to publicly available? If not, I'll add additional logging in a snapshot build for you to try. Let me know. Thanks!

[Cristian MG]

Thanks I fixed the bug and I comment the issue thankss for the support

[travis]

Awesome! Thanks for following up!

[travis]

So, the issue is good to close, right?

[Cristian MG]

Yes I'ts not a regression it was simply a mess with coroutines scope
