Very Promising
I had my first outing with the app and the new MCR54 firmware, everything worked fairly well with only a couple of instances where the bluetooth handshake was a little intermittent. I'm not sure if you have pair the receiver with your phone or if the app is supposed find the receiver on its own. Still, I loved the ability to change the receiver name on the fly and have it automatically carry over into the track name of the Sound Devices 833, pretty slick. Looking forward to the further development of the app!
