You guys having trouble with Bluetooth: is this while WiFi streaming? or playing files from the SD card? If you're playing local files, you should switch off WiFi. If WiFi streaming, use 5gHz if possible. Why? Because Bluetooth and 2gHz WiFi use the same frequencies, so they can interfere with each other. In fact, some devices (many Motorola phones, for example) actually use the same chip and antenna for both Bluetooth and WiFi, time-sharing if both are in use simultaneously. I don't know if this is the case or not with the R3Pro (either version).
