RS 250A what bluetooth codex?

What kind of bluetooth codex does the 250A support?

@Toba

Currently, Rose devices only support SBC codec when connected via Bluetooth.
However, there is a request for a higher codec when using BT, so we are reviewing to support AAC and LDAC codecs in the future.
In the case of aptX, it is not considered.
AAC and LDAC will be positively reviewed and added.

Thank you

Thanks for the update. Would it be possible to upgrade the 250 A with an e.g. aptx Bluetooth USB dongle?

@Toba

The RS250a has built-in Bluetooth and WiFi modules.
The separate use of an external Bluetooth dongle is unlikely to have a good effect on sound quality and speed.

Thank you
