EstimoteTelemetry + Eddystone

[alexander]

I’ve tried to get battery level from Eddystone-TLM, but it’s no so easy, because I can only get the battery voltage.
So I activated Estimote Telemetry.
I’ve also activated Eddystone-UID.

Eddystone-UID is using for simple indoor location. If a beacon is detected, the app knows, in which room is the user.
Now, I want additionally to get the battery level and temperature. I do it with TelemetryListener.

The problem is:
with EddystoneListener I get list of Eddystone-objects,
with TelemetryListener I get list of EstimoteTelemetry-objects.

First have macAddresses, second deviceIds.

1. How can I match the data to the same beacon, if I only have Eddystone-Object and EstimoteTelemetry-Object?
2. Or is it possible to get deviceId from namespace and instance of beacon?

Yup, that’s a bit of a tough one (;

One solution that comes to my mind I already sort-of described here, in point 4:

How to associate Eddystone with Estimote Cloud

iOS Bluetooth API doesn’t actually expose the MAC addresses of Bluetooth devices. Instead, they only provide you with an ephemeral GUID, but keep in mind this GUID might change e.g. when you restart Bluetooth or the phone. And it will certainly differ between iOS devices. But back to your problem (: Here’s how to go about it: Enable Eddystone UID and Eddystone TLM on your beacon. Both the UID and TLM packets will have the same MAC address. (On iOS, I think that should mean they have the same …

i.e., use the /v2/devices endpoint to fetch all your beacons’ data, including their device identifiers and namespace and instances, and cross-reference that.
