Hi @orestesgaolin! Not the answer to your question but I'm using Polar Verity Sense myself with Flutter and the polar flutter wrapper. I wonder how are you starting and reading HR and PPI recordings offline, because I can't get it to work? Stuck with his issue: #528 |
|
I wish I could help you @abbjetmus, but we don't use offline PPI recordings, only HR. When it comes to settings we just pass empty value: private val hrRecordingSettings: PolarSensorSetting by lazy {
PolarSensorSetting(mapOf())
}
// and later
polarBleApi.startOfflineRecording(deviceId, feature, hrRecordingSettings, null) |
Thank you so much, this is actually what I was needing. Both HR and PPI are computed/derived data from PPG so should be the same approach. I never tried passing an empty map to PolarSensorSettings I assinged null to settings. if (!offlineRecordingStatus.contains(PolarDataType.acc)) {
var settingsAcc =
await polar.requestOfflineRecordingSettings(
identifier.value, PolarDataType.acc);
await polar.startOfflineRecording(
identifier.value, PolarDataType.acc,
settings: settingsAcc);
}
if (!offlineRecordingStatus.contains(PolarDataType.ppi)) {
await polar.startOfflineRecording(
identifier.value,
PolarDataType.ppi,
settings: PolarSensorSetting(<PolarSettingType, int>{}),
);
}``` |

Describe the bug
There are 2 cases where IndexOutOfBoundsException happens
Case 1 - offline recording
When starting offline recording the following exception is sometimes thrown from this
slicecall:polar-ble-sdk/sources/Android/android-communications/library/src/main/java/com/polar/androidcommunications/api/ble/model/offlinerecording/OfflineRecordingData.kt
Line 288 in 71191b5
This exception seems to be irrecoverable due to following, and this means the PPI stream stops:
Case 2 - starting PPI stream
The exception is similar but has a different stack trace:
polar-ble-sdk/sources/Android/android-communications/library/src/main/java/com/polar/androidcommunications/common/ble/TypeUtils.kt
Line 37 in 71191b5
How to Reproduce
In case of PPI streaming we just call following API on some phones:
Expected behavior
The
sliceoperation should not fail and PPI stream should continue, and the offline recording should be able to startThe text was updated successfully, but these errors were encountered:
