startNotifications

[dgnovo]

Hello,
i want to use with a Ionic Capacitor app, the startNotifications function to receive notifications on a Custom Service.

I receive this message:
Setting notification failed
when i use
await BleClient.startNotifications( device.deviceId, service, characteristic, (value) => { console.log('current value', value); } );

The Custom Service doesn't have a descriptor on charateristc and notify property is set to true.

I see on Device.kt this error is at the line
val descriptor = characteristic.getDescriptor(UUID.fromString(CLIENT_CHARACTERISTIC_CONFIG)) if (descriptor == null) { reject(key, "Setting notification failed.") return }

Is it possible use startNotification if charateristc doesn't have a descriptor?

Is it possible use startNotification if charateristc doesn't have a descriptor?

No, this is currently not possible.

What peripheral is this? Do you control the software/firmware of the peripheral?
