Undocumented quantity "Hr"

[Aeefire]

You can subscribe to the quantity "hr" to receive the heartrate and get the server response:

Selected stream is not valid! Available streams: [acc,bat,bvp,gsr,ibi,tag,tmp]

However, afterwards, you still receive the heart rate every few seconds! So it does in fact work, but is not documented + results in an error message.

I think it might actually be part of the ibi stream. At least, starting the client and only subscribing to ibi will cause Hr data to start streaming (provided it can find a pulse).

Did you manage to connect to the server ? If so how ? ^^
