I am not sure how the WIDI and BLE-MIDI differs, but I guess the safest way is to set the RK008 in BLE mode to just 'ON' (BLE pheripheral) and not 'PARTY' (=BLE Central Host) because WIDI has it's own hub app? There's also a 'DIRECTION' setting in the RK008 where you can decide if the BLE records only or sends only (or does both, but in some situations it can choke on a BLE MIDI loop). The RK008 BLE is more designed to quicky add a nanokontrol studio or small controller stuff on it for example, not really for big wireless setups. Also note the RK008 does not send clock over BLE, we did not found it reliable enough.
