RCA analog audio to Bluetooth transmitter
What sender do you recommend?
I have seen so many on Amazon and Ebay.
The distance is under 10m. The signal comes from a projector, output RCA, left and right.
I want to send that audio wireless to an audio amplifier which has Bluetooth receiver.
Most of the senders have a small battery incorporated, but I do not care, it can be also with power adapter. In fact those with battery have a kind of standby mode to avoid battery discharge. That is something that I do not really need.
One important request is this: when the analog signal comes (projector starts playing) I need that Bluetooth audio transmitter to send the signal right away. I do not want to go and press a button somewhere on transmitter. It should be like a self-activating, self-wake up mode, in case enters in standby. This is very important because that Bluetooth transmitter will be placed near the projector somewhere high and I cannot go every time there to activate manual the Bluetooth transmitter. I want to see this feature somewhere mentioned/explained before I buy it.

If everything relays only on trying, without knowing in advance from manufacturer, user guide/manual or personal experience, then I had in mind a cheaper version:

The truth is that I have a small Dodocool (what a name!!) Bluetooth receiver and works with Bluetooth V 3.0.
Do you think are any incompatibilities between my Dodocool (I like this name!) Bluetooth Receiver (Bluetooth V 3.0) and the XCSource Bluetooth Transmitter (Bluetooth V 2.1) ?

I would expect a 3.0 receiver to be more forgiving of a 2.1 transmitter than a 4.1 receiver would be; but, you can't possibly know until you try it.

I looked over the compatibility between Bluetooth backward versions:

Except the speed and the low power consumption I see no other differences/issues.

So it remains only to try it out.
I am a bit uncomfortable about that.
In my question, this was all about, to know it in advance from technical specs for sure before I buy it.
I do not want to spend the money for something that I am not sure. That is the purpose of the question and to know in advance.
That makes me unhappy.
Unfortunately I have to close the question because I will be away for 2-3 weeks.

I am afraid about standby problem.
My dodocool enters in standby if no audio signal is detects for a period of time.
I must avoid that for transmitter.
On german website (where I can buy it) is more expensive:

That is nice, but using Bluetooth give me the possibility to send audio also from iPhone/iPad or Notebook, so I ma not stuck only with a specific pair.

I will close the question for now.
When I have time probably I will buy one of those Chinese cheap transmitters from ebay/amazon and jut try it.

I need only a Bluetooth transmitter attached to the projector RCA audio output.
It must not go in standby or sleep mode or if it goes, which is fine, then it must wake up automatically when audio signal is present at the output of the projector.
Which transmitter can do that?
