Daisy-chain Sync 40: protocol specs

It is possible to use two Sync speakerphones with a Bluetooth-paired mobile device. In this case the two Sync 40 are linked together in a daisy chain via a wireless connection.


Does anyone know how the devices are linked internally? I assume it is accomplished via a Bluetooth connection as well. Our customer with high certification standards asks about the specifics of the wireless connection as well as the Bluetooth version that might be used for the daisy-chain.
