What is the schematic diagram of M5 player if it can transmit LDAC in USB DAC mode, or it can't either?

Dear friend,

The M5 doesn't support Bluetooth output when using as USB DAC.

Best regards

How are Bluetooth TX codecs selected, i.e. ensuring that aptx-LL is chosen for TV viewing (providing the receiver is capable), or ensure that aptx-HD is transmitted for music (when the receiver supports aptx-LL as well)?

I looked through the manual (attached), but could not find details as to aptx auto-switching.

Update: The Control App allows for codec priority selection. Not sure if it can only be set when in RX mode...If so, assume it stays in that mode when switching to TX.
Connect the BTA30 to a mobile phone and switch it to RX mode, so that it can be controlled by the FiiO Control APP.

Looking forward to the BTA30's arrival. I plan to use aptx-LL with the Shure RMCE-BT2, and with an old Linksys HGA7S SMA High Gain Antenna, this one, https://www.bestbuy.com/site/linksy...antenna/6834303.p?skuId=6834303&intl=nosplash

Dear friend,

In Bluetooth TX mode, you could double click the 'pair' button in the BTA30 to switch Bluetooth codecs of the BTA30.

Is the antenna connector BNC or SMA? Please confirm as it was announced earlier in this thread to be SMA but the website mentions BNC.

The website pic shows the connector as being threaded so it is likely SMA (or TNC). I have both these covered with high gain antenna upgrades, but not BNC.

Dear friend,

I confirmed with the engineer that the antenna connector is SMA.

Best regards

Hi, all. Just received my BTA30 from Aliexpress. Very decent build quality with a small form factor, neat little thing!

Two problems on transmission mode so far, however, it seems that the BTA30 only receives the AAC codec, but doesn't provide transmission. SBC connection on my WF-1000xm3 seems to consistently exhibit audible distortions between certain frequencies, so I was hoping AAC might do something for it, ah well.

Secondly, I can no longer adjust the volume of my audio from my computer. Neither the windows volume mixer, nor the volume knob on the BTA30 works. Only the volume control on my computer applications seem to have an effect (Youtube, Tidal). Also, the max volume is occasionally too soft now on certain videos and songs.

Any idea on what I'm doing wrong? I'm using only the USB-C input for my BTA30 for both the power and digital signal, if that matters.

Dear friend,

Thanks for choosing our BTA30.

1. Yes, the BTA30 does not support AAC format in BT TX mode. Does your Bluetooth headphone support another Bluetooth codec? You could also clear the pairing record by holding the power+pair button for 5s, then reconnect for check.
2. Are you using the BTA30 as USB DAC and connecting it to the Bluetooth headphone at that time? If yes, the volume is not adjustable from windows volume mixer and the volume button of the BTA30. Because under this mode, the audio signal is not transmitted through the CT5302 chip which controls the volume. While the Bluetooth chip itself does not have the function of volume adjustment, so the volume knob on the device will be invalid at this time.

Best regards

For 2. you may want to research Windows Absolute Volume (and make a Registry Key change). If that doesn't work, perhaps research BtTweakerSetup-1.1.2.1.msi
