Eddystone Relay Example

[Kalpesh Brahmbhatt]

Kindly give suitable example or suggestion for Eddystone Relay / Rebroadcaster. I have checked on Beaconing example but it could not rebroadcase eddystone beacon.

Hi Kalpesh Brahmbhatt,

May I ask what you mean by relay/rebroadcaster? I have taken a look at the eddystone spec & I could not find any mentions of relay or rebroadcaster.

I want relay example as our project is to track eddystone beacon and send to central unit to extend range we require relay. Already we have purchase more than 100 eddystone beacon (nRF52832 based).

So basically you want to create a tracking system using eddystone beacons & track the location of the asset you are tracking, correct? Then, you want to relay this position back to a central device. Are you planning on using RSSI & trilateration to figure out the beacon location? Do you then want to do post processing of the asset position using the central device?

This devzone case could be very interesting for you. The whole point of a beacon in this use case is to tell the asset device, "Hey, I'm a beacon & this is my position". In this example, I guess the smartphone does the post processing work to take multiple positions from the beacon to trilaterate the smartphone position & do some fancy post processing to get an accurate position within +- 3 meters. 

Beacons on their own do not relay signals. Do you want your beacons to be battery powered or connected to a power source? You could use a bluetooth mesh network based on the beaconing example in the mesh sdk v2.1.1 to relay messages back to a central device. The only problem is that the radio is on most of the time in the mesh devices to be able to listen to incoming mesh packets, so these devices could not be battery powered.

Exactly we want relay to locate person. This is for Hospital project. I have tried beaconing project but it could not relay eddystone or ibeacon advertise to Beacon Scanner.
