Eddystone scanning - TLM packet

Eddystone scanning - TLM packet

[Jason Anderssen]

Hi,

I have successfully written code to scan for iBeacons using bluez, I was wondering if there is a link to some example or doc that explains how to detect the eddy stone different frames, for example, the main one I am after is the  Eddystone-TLM data which can be interleaved.
Any help or direction I can search would be fantastic.

Thanks in advance for any advice or help.

Cheers
Jason

The different Eddystone frames are identified at the start of the
service data. TLM is 0x02 as detailed in the spec at:
https://github.com/google/eddystone/blob/master/protocol-specification.md

You may also find this beacon cheat-sheet useful that was posted on Twitter:

Hope that helps.

Barry

Btw, I will be sending patches to add support for creating advertising
instance with bluetoothctl, so if all goes well it would be possible
to do this with bluetoothctl.
