Dear friend,

The Bluetooth codec is not depended the BTR3. Maybe you could try to check the APTX using another mobile phone which supports APTX?

Thank you, yes AptX work with phone fine (Samsung Galaxy S7) which I know support this codec, but it's weird that also work with my Windows 10 PC with Asus BT400 USB dongle which are on Broadcom BCM20702A0 chip not any CSR chip, FiiO flash on purple so it mean use AptX also, but does it mean on 100% that it use AptX ?
Does FiiO led color are always 100% accurate recognizing which codec use ?

Dear friend,

I communicated about this with the engineer as well. The LED indicator would show the correct working Bluetooth codec. If APTX is not  supported, generally the Bluetooth codec will switch to SBC instead. And the indicator would show Blue instead.

Thank you Jojo, so on Windows 10 USB Broadcom BCM20702 USB Bluetooth dongle Asus BT400 work with Apt-X nice, I guess even manufacturer Asus do not know about that
I thought only USB Bluetooth dongle based on CSR chipset will work with Apt-X.

Hi. I also encountered with wrong led working. Everywhere LDAC is set, all soft showing me LDAC usage - but BTR3 still flashing purple, also in USB DAC mode its use purple too despite that in guide in FIIO music app and in several review around net - it must be white. I tried upgrade firmware (v1030), tried to reset device - nothing helps. Please Fiio, comments this. Is it defective device or its already known bug in firmware ?

Same here, purple LED while phone says LDAC....  I bought it because of LDAC. And LHDC (HWA) does not seem to work (hick ups in music playback)

Dear friend,

Actually, the white led indicator will also come with purple light, it is normal phenomenon so please don't worry. You could compare the colour with the one using APTX Bluetooth codec, and you will find that the indicator of LDAC Bluetooth codec is white.

As the latest lossless Bluetooth transmission decoding standard, comparing with LDAC/APTX, HWA Bluetooth decoding is still less stable. On the one hand, it is because of the maturity of technology. And more importantly, as a wireless transmission standard with limited transmission bandwidth, there is a contradiction between transmission stability and bandwidth.

Our engineer has also communicated the issue with HWA with the engineers in HuaWei. Improvement is needed in their end as well.

Best regards
