We are working on a similar solution using React Native. Our goal is to connect to a BLE device, retrieve data, and integrate it into our app.

We have tried the solution mentioned in this answer and successfully identified the serviceUUID and characteristicUUID that are notifiable. However, we are not receiving any data from the notifiable characteristic.

Here’s what we’ve already checked:

Permissions: Ensured all necessary permissions (location, Bluetooth) are granted. Notification Enabled: Verified that notifications are enabled for the characteristic using isNotifiable. Device Behavior: Used apps like nRF Connect to confirm that the device is sending data when notifications are enabled. Subscription: Subscribed to the characteristic's notifications in the app using the correct UUIDs. Despite these efforts, no data is being received.

Has anyone faced a similar issue and found a solution? Any insights or guidance would be greatly appreciated.
