@FiiO Are you actively working on why HWA (LHDC) broke with 1.2 firmware? (At least it has for me on my Huawei P20 Pro.)

Waiting for the btr5!! i wiilo buy it

Please add firmware update support for OSX! I don't have access to windows computers.

Agreed, it would be great if @FiiO would officially support firmware upgrades on linux and osx as well as windows, especially as they seem to be using an open standard for flashing firmware anyway...


In the meantime, you might want to check out some of my earlier posts on the subject:

From https://en.wikipedia.org/wiki/USB#Device_Firmware_Upgrade

Might not be officially supported, but you might want to try your luck with something like http://macappstore.org/dfu-util/ or https://www.thesycon.de/eng/dfu_utility_macos.shtml

(I successfully upgraded the firmware of my BTR3 on linux)

And the long and boring version:

<snip>
"FiiO BTR3 linux firmware upgrade"

Disclaimer: This procedure is not supported by the vendor and you are knowingly risking bricking your device if you attempt this.

So, not having a windows machine and feeling pretty reckless, I noticed the upgrade instructions seem to refer to a generic dfu upgrade, and went looking for a firmware upgrade tool on linux.

My first hit was "dfu-util" from http://dfu-util.sourceforge.net/, which is actually available in fedora as "dfu-util-0.9-6.fc29.x86_64" at the time of writing.

Following the instructions from the upgrade guide, I first set the device into program/dfu mode, so it shows up like this:

[cybdev@localhost ~]$ dmesg
<snip>
usb 3-1: new full-speed USB device number 7 using xhci_hcd
usb 3-1: New USB device found, idVendor=0a12, idProduct=ffff, bcdDevice=25.20
usb 3-1: New USB device strings: Mfr=0, Product=2, SerialNumber=3
usb 3-1: Product: FiiO BTR3
usb 3-1: SerialNumber: ABCDEF0123456789
<snip>
[cybdev@localhost ~]$

So having installed the dfu-util package and previously downloaded the firmware from FiiO, check that the device is known by dfu-util:

[cybdev@localhost ~]$ sudo dfu-util -l
dfu-util 0.9

Looks good, so copy the device string and point it to the firmware file you downloaded:

[cybdev@localhost ~]$ sudo dfu-util -d 0a12:ffff -v -D /tmp/BTR3_1.0.dfu
dfu-util 0.9

I've got to admit I was a little nervous when it first told me the device wasn't in DFU mode, and especially after it lost contact with it when the firmware was flashed.

However, when unplugging it, turning it back on manually, and re-plugging it, everything looked OK:

[cybdev@localhost ~]$ dmesg

@FiiO Are you actively working on why HWA (LHDC) broke with 1.2 firmware? (At least it has for me on my Huawei P20 Pro.)

Dear friend,

You are using the HWA from the mobile phone or the FiiO Music APP?

If you are using the HWA from the Huawei mobile phone, please try to switch frequency from 96kHz to 48kHz in your mobile phone.
And please try to turn off and on the FiiO Music app after turning on the HWA option. Then switch to next file after turning on the FiiO Music app at the second time.

Best regards

Thanks for this!

So I (successfully) installed the one for Macos: https://www.thesycon.de/eng/dfu_utility_macos.shtml.. But now I don't know what to do. I put my device in DFU mode, connect it to my Mac, run sudo dfu-util -l in terminal and it does not find my device, it just states the dfu-util version (0.9)

Yeah that does NOT work.

So I got it to recognise my device, but the update won't work. It says something like "disconnected before reset?" and then it stops. Scary, because the device wouldn't restart for a while..

Sorry to hear that... Perhaps you could share some details about your platform?

And just to make sure, - you did follow the instructions to put it into DFU mode first?
And running the commands or gui app with superuser privileges (note the sudo part from my linux terminal output)?
(I should mention I booted from a usb stick without selinux/apparmor and such enabled, just in case)

As for the part where it wouldn't restart for a while, I encountered that as well, it took some effort to power cycle it after, but in the end it did come up with a new firmware version in the app, and the new functionality was there...

HWA does not work on my Samsung Note 9 + BTR3 1.2 + FiiO application 1.1.2, too. But I have not tried with firmware 1.1. There are a lot of drops (1 drop every 2 or 3 seconds). I tried all FiiO recommendations (turn off and on the FiiO Music, ...). I hope FiiO team will fix HWA issues soon.

I have ordered a BTR3 last night. Was looking at high end DACs such as mojo and ifi xdsd, q5, oppo etc. I am buying primarily for preamp dac as interface between phone and alpine h800 processor in car audio system. I tested max output voltage on my Galaxy s10 5G is around 0.28v without atmos or 0.4 with. I need to set amp gains too high as this output is not ideal at all. Looks like the btr3 should put out just under a volt from my calculations which should help snr. Anyway, I went with btr3 due to really wanting the convenience of ldac bluetooth vs usb cable and special media player with usb dacs such as mojo. I am waiting for the Fiio Q5s! I really hope Fiio use usb c connections on it though as it looks like they are using micro usb in press photos .

@FiiO A few questions:
- Is there a BT5 FW update for BTR3 planned? The BT chip you are using supports BT5 and ES has updated their device. The feature I want from bt5 is slot availability mask, pretty much the only audio-related improvement.
- Is there an ETA for BTR5 ? In may, your twitter said that you wanted to release "in the coming months".

I’m on a Mac, high Sierra so maybe that’s why it doesn’t work. I was able to put the brtr3 in dfu mode I guess. I know because when I mistakenly did not, dfutil would not recognize it. So I assume when it comes up with the device Id and all, it means it’s in dfu mode. I’m a bit scary to run the update again, then I could copy the exact messages. My terminal messages looked a little different and most of all shorter than the one you posted.Its not updated that’s for sure.

Dear friend,

Did you try turn off and on the HWA option in FiiO Music APP and check again?

Dear friend,

BTR3 uses the bluetooth 4.2. Actually the Bluetooth 5.0 may not help with the sound quality too much compared with the bluetooth 4.2. Moreover, some bluetooth codecs like LDHC still hasn't adapted to the bluetooth 5.0, we decided to use the mature bluetooth 4.2 version for BTR3.
We do not have an ETA for BTR5 currently.
