Active RFID tag or BLE Beacon location sensing

[Go Joe]

Simple put, I am looking for the best way to get a vector towards a (tagged) object using a Pi3. Sensing range needs to be at least 3M. This is to be used for a pi robot's indoor sensing of objects.

I am trying to build an application that is capable of sensing the relative location of several active RFID tags, BLE Beacons or some other form of tag. A vector towards each tag would be ideal, but distance to tag/beacon would also work. Does anyone know how to accomplish this on a Raspberry Pi 3 running Windows 10?

I am a C# coder so I am thinking I can use the Pi3 onboard bluetooth to receive multiple BLE beacon signal strengths then triangulate, but I don't want to have to re-invent the wheel. I have been unable to find any sample code for this exactly and there might be a better direct method to get the vector towards an object using Pi3, seem like this would be a common need in the Pi world.

Well, you can get signal strength (RSSI) from iBeacons, but I wouldn't think it would be precise enough for your needs. I don't think RFID would give you the range.

I would like to go with BLE Beacon. Here is my reference for the same- https://blog.roambee.com/supply-chain- ... le-beacons

You could try triangulation techniques with bluetooth beacons or in combination with other techniques.
