What is the difference between normal Advertising and Eddystone ?

[Nijat]

Hi, guys, I tried nRF5_SDK\examples\ble_peripheral\experimental_ble_app_eddystone example on nRF52832 and it works perfect.

And I compared the code with the normal BLE advertising example. But I cannot find any difference between normal advertising and Eddystone advertising except the advertising Data Structure ?

Can anyone tell there is other difference ? Does the difference only exist on only data structure protocol part ?

Hello Nijat,

 The "normal" advertising example aka. "ble_app_beacon"  vs. Eddystone beacon example:

They both uses the BLE broadcast methodology of putting advertising packet on the BLE channels 37.38 and 39 in the 2.4GHz band. 

"Eddystone is a protocol specification that defines a Bluetooth low energy (BLE) message format for proximity beacon messages. It describes several different frame types that may be used individually or in combinations to create beacons that can be used for a variety of applications." (source)

Eddystone is its own protocol and has to be handled as specified by the Eddystone protocol Specification. 

The "normal" advertising is non-connectable and do only broadcasts information, while Eddystone is also connectable and can be configurable on the fly.

 

I would also like to add this little blogpost comparing iBeacon and Eddystone which can be interesting for you to read.

 

If you have more questions or something is unclear, do not hesitate to ask and I will try to answer them at my best ability.

 

Best Regards,

Great introduction and great post !

So it is the matter of message format they are sending.

Thanks Martin, I have great progress from what you are providing.
