ESP32 Crash on Android on IPhone it works

[coltc50]

Hello,

I'm new at arduino and I don't know how to fix my problem. I asked at the arduino forum but didn't get a answer,

I try to get this script to work:
https://github.com/jstiefel/esp32_komoot_ble

When I try on IPhone everything works. But I don't have an IPhone and on Android the script is make a guru meditation after connect.

I tried a lot but didn't found the problem.

Here a Log:

What's the problem and how I can fix this?

[chegewara]

getDescriptor(): << getDescriptor: Not found

Which is strange, because this characteristic can send notifications:

22:22:43.145 -> - Found our characteristic 
22:22:43.145 -> CanRead : 1 
22:22:43.145 -> CanWrite : 0 
22:22:43.145 -> CanNotify : 1 
22:22:43.145 -> CanIndicate : 0 

So, i am suspecting that android app is broken and does not have required 2902 descriptor.

[coltc50]

Thank you. But how can I fix this?

When I comment these two lines out it didn't crash but then it doesn't notify...

//pRemoteCharacteristic->getDescriptor(BLEUUID((uint16_t)0x2902))->writeValue((uint8_t*)notificationOn, 2, true);

//pRemoteCharacteristic->registerForNotify(notifyCallback);

[chegewara]

Fix android app.

[coltc50]

That I cannot do because it's the official Komoot App.

Is there no work around I can do on ESP32 side?

Maybe hardcoding address or something?

[chegewara]

Like i said earlier, this means android app.

What you could do is to comment out those lines:
https://github.com/nkolban/esp32-snippets/blob/master/cpp_utils/BLERemoteCharacteristic.cpp#L465-L466

and this one in your app:

//pRemoteCharacteristic->getDescriptor(BLEUUID((uint16_t)0x2902))->writeValue((uint8_t*)notificationOn, 2, true);

BTW nice device

EDIT this will obviously brake iPhone connection

[coltc50]

It works, it works... Thank you so much. No problem to break IPhone because I didn't have one...
How can I donate? Thank you again!

Now I can make me thoughts about a housing.

Great. You made my day!

[chegewara]

Im glad it worked.

[coltc50]

Sorry to post again but since a few days it doesn't work anymore. Now it stuck anytime. Don't know witch update caused this.
