Streaming Heart Rate Data to Linux Application

[peterdavidfagan]

Hi Protocentral Team,

I am working on streaming data from the device to a separate linux application. I am using firmware V1.2.99 on the Healthypi Move device and I am attempting to connect to the device using bluez.

I have been successful in pairing with the device, however, when I turn notify on or attempt to perform a read on the heart rate or temperature characteristics I get Failed to read: org.bluez.Error.NotPermitted. My goal is to simply stream data from the watch to my linux application, I wished to ask for any recommendations you would provide on this as I am only starting to familiarize myself with this repository.

Many thanks for any assistance you can provide.

Ah I see that currently the characteristics I am looking at don't implement callbacks for notifications, I got some other streams to work though.

I am guessing it would make sense to create multiple recordings at a given frequency and to maintain a queue to transfer these to my application? I am still just getting to understand the firmware implementation so apologies if the current issue/thoughts are a bit naive.

Hi ! I'm experiencing the exact same issue with firmware V1.2.99. The Heart Rate and Temperature characteristics return "Not Permitted" errors when trying to read or enable notifications.

Did you find a solution for accessing HR data in real-time? I see you mentioned getting "some other streams to work" could you please share which characteristics/services worked for you?
