Good evening,

I bought this transmitter https://www.amazon.fr/gp/product/B07CZ4C8K2/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1
The problem is that I'm struggling with the connections, I don't know anything about it, and for me, all these connections are a real mess :pt1cable: .

First, let me tell you that from my Asus T200TA laptop, in "manage my Bluetooth devices," only the bt b19 device is connected (is this normal????) and if not, how can I get other devices to connect?

Furthermore, with this transmitter, I have 1 audio cable of 3.5mm + 1 female to 2 male RCA 3.5mm cable + 1 digital optical TOSLINK cable and a USB charger for the transmitter.
Can you tell me which wires I need to connect and where exactly so that my computer can transmit sound to my soundbar?
Additionally, on this transmitter, should I set the cursor to "TX" or "RX" and "SPDIF" or "AUX"?

    Hello,
    It would be good to provide some additional important information

    You mention other devices, but which ones?

    Is the only purpose of this transmitter to send audio from the PC via Bluetooth to the soundbar?

    Your "transmitter" is actually a Transmitter Receiver
    Switch on RX:
    it receives Bluetooth waves and converts them into audio signals either optical digital (SPDIF socket) or analog (Aux socket)
    Switch on TX:
    It transforms the audio signals received via SPDIF (optical) or AUX (analog) inputs and sends them via radio signal (Bluetooth) to a Bluetooth receiving system.

    If your only goal is to transmit the sound from your PC to your soundbar via Bluetooth.
    The Bluetooth transmitter/receiver must be set to RX (receiver)
    and you should use the optical cable between your BT-B19 and the soundbar.
    The optical cable connected to the RX optical socket and to the TV or BD/DVD input of the soundbar
    Then, you will need to ensure that the PC sends the sound via Bluetooth on one side and that the soundbar is directed to the TV or BD/DVD input depending on the socket of the soundbar where you connected the optical cable.

    Question: is this soundbar far from the PC?

    Actually, the problem is that I don't know how to make a Bluetooth adapter work; for some, it might seem trivial, but for me, it's quite complex...

    The only change since last night is that in "manage my Bluetooth devices," only the bt b19 data has changed and is listed as "paired" instead of "connected" (to be honest, I don't know if that's normal).

    The issue is that on the adapter, I've set the switch to "RX" and "AUX," and I'm not sure if I'm already wrong on that point?
    Also, among the 3 cables I received with the adapter, I'm wondering if I need to use all of them or not... the user manual is not very clear, written in English, German, and Chinese with not very explicit diagrams.

    Furthermore, on my soundbar, which does not have Bluetooth functionality, whenever I test my connections, the input function activates on the device regardless of what happens. What does that mean?

    Thanks again.
