Would you have any interested in expanding BLE beacon support for Ruuvi Tag devices? This are beacons that broadcast environmental data such as temperature, humidity and X,Y,Z-axis motion described in their protocol document at https://github.com/ruuvi/ruuvi-sensor-protocols/blob/master/broadcast_formats.md
- Data format 3 (also known as RAWv1) and
- Data format 5 (also known as RAWv2) are most commonly used.
This could be a beacon device not only for presence detection but add also extra value with the environmental data.
