Some observations
- Use the latest itoo cersion
- Adjust the blocks ro follow the changes of the last version... there is no RegisterEvent procedure anymore
- You forgot the argument x in your background procedure named run
- You have to connect to the BLE device also in the background... searching for BLE examples in the itoo thread will show you how to do it. . It does not look kike you did a search
- to find out, if something is working in the background or not, use the Notifier.LogInfo method for debugging and use logcat to check the log.
