Hello,
How do I stop the notifications correctly?
My current situation is that when I enable - disable - enable notifications, I then get duplicated values. More times I disable/enable, the more duplicates I get.
Here is my code:
Start notifications:
if let service = peripheral.discoveredServices?.first {
try await peripheral.discoverCharacteristics([Constants.Device.sensorUUID.cbuuid], for: service)
self.characteristic = service.discoveredCharacteristics?.first(where: {
$0.uuid == Constants.Device.sensorUUID.cbuuid
})
if let characteristic {
try await peripheral.setNotifyValue(true, for: characteristic)
trackingState = .trackingEnabled
}
}
for await characteristic in peripheral.characteristicValueUpdatedPublisher.values {
guard characteristic.uuid == Constants.Device.sensorUUID.cbuuid else { return }
let value: Int? = try? characteristic.parsedValue()
}
Stop notifications:
guard let peripheral = peripheral, let characteristic, characteristic.isNotifying == true else { return }
do {
try await peripheral.setNotifyValue(false, for: characteristic)
trackingState = .trackingDisabled
} catch {
showErrorBanner(error)
}
Note: I also tried try await peripheral.setNotifyValue(<#T##enabled: Bool##Bool#>, forCharacteristicWithUUID: <#T##UUID#>, ofServiceWithUUID: <#T##UUID#>)
