Could not find service with uuid error on IOS React-native BleManager

I do the same things on android it works but on IOS it doesn't work.

  • I can scan devices on IOS and Android.
  • I can blemanger.connect to any device on IOS and Android..
  • I can't startNotification on my device on IOS but can on android.

I tried this:

I can connect to my device using my variable: connectedDevices.id with is in this case "E8595779-BEF2-FB78-741E-E855465F760C"

As seen on the picture below, I connected to device using ID, But it can't find service with UUID "FFE0" But actually there is service with UUID "FFE0"

All Info Present Here

Solution

  • It finally worked, What I learned is if you want ble manager to work on IOS, You should make fallowing changes on your working Android code,

    • Service and char UUID should be short form.
    • You should retrieve services after you connect.
    • You should use writewithoutresponse. Much love
