Hello Michael,
Thank you for contacting the Cardo Systems Support Center.
Most Bluetooth dongles that we have tested are not sophisticated enough to maintain the Bluetooth connection with a scala rider headset once they are interrupted by another source, such as the Q2s Intercom feature. These dongles are generally designed only to be used specifically for sending audio from a music device to a Bluetooth speaker, and are not designed to be using in conjunction with a headset that switches between multple audio sources, so I’m afraid I can’t recommend a specific adapter or dongle that may work properly with the scala rider headsets.
Another issue you may encounter is with the Bluetooth signal that is being sent from the adapter or dongle that you may try. If you are using a scala rider Q2, and not the Q2 PRO; the scala rider Q2 is a mono-only device that cannot receive a Stereo Bluetooth signal, where as the scala rider Q2 PRO can receive both mono and Stereo Bluetooth signals.
If the adapter or dongle is a Stereo device and you are using the scala rider Q2, this may also explain any connection issues that you might encounter.
Please feel free to contact us if we can assist you with any other questions.
Best Regards,
