i’ve written a basic BLE beacon scanner for iOS, with parsers for ruuvi tag raw and Eddystone formats. Since there seems to be nothing else with ruuvi support on iOS right now, i’ve published it - maybe somebody will find it useful.
More information here: http://corebeacons.fluthaus.com.
It’s nothing fancy, just a byproduct of playing around with my ruuvi tags and dipping my toes a bit into Bluetooth LE, so please don’t expect too much. And naturally, it’s limited in some aspects by these many frustrating shortcomings of the weird iOS CoreBluetooth API… i’ll try to contain myself and not rant at length about it
