I tested the stereo modes again:
In transmitter mode is joins both channels and sends a mono signal
In receiver mode it plays ONLY left channel on left and right channel (right channel is completely lost)
So, in the end it's mono at best :(
Even though it's not amazing, it may be great for incorporating BT capability into old devices due to it's size.
I think this BT600 model designation is meant to be a fake Platronics BT600 www.poly.com/u...

I made the same configuration, but one on a old TV (TX) and other on a 2.1 system (RX). Besides the mono experience, I'm facing some delay between the image and sound. Do you experienced as well?
To be honest, I used those only for podcasts, but when I connected the another transmitter to the TV there was some kind of delay (maybe 0.2-0.3s). When I tried older headphones (BT 2.0 or 1.X, I can't remember) it was ok. I think when it uses some kind of more efficient codec it takes longer to process and causes a delay.
Where the hell is that music coming out from?
Hi,
Great video and detailed explanation! It helps me a lot to make the same solder bridge on my device in order the receiving mode to be first, once the device is turned on. Now I am kind of struggling the fact, that any single time, when I power it (I am using it in my car), there is a voice welcoming message “Receiving mode”, which drives me crazy. Its not a big deal, but it is annoying. Do you know how this message could be remove or deleted somehow? I am not into this field and am not sure even is this technically possible? Many thanks in advance!
Regards
I think it's a part of ROM in that chip, so no options here since it's very integrated.
I had another device with separate memory chip and when I disconnected the signal line the device refused to start completely. I could disconnect the memory chip AFTER starting the device and it was quiet, but woudn't start without it.
@@pandaengineering It is very interesting, because if I'm not mistaken, the whole message is "Bluetooth receiving mode", or something like that. I do not remove the button, only made this solder bridge. And once I turned on the ignition of the car I can hear like the 60% of the message "Ecieving mode".... Even Receiving is not sounding complete. I am not sure if there is some delay in the noise, or somehow I managed to terminate partly the message (probably not)? But anyway... If someone put some more light in the case, of find out something will be pretty useful.
The two of them just paired up instantly? Because i tried connecting my BT earphone to this device but they do not pair
Sometimes when that happens I turn of both, turn them on again, put headphones into pairing and then it works. For my newer headphones I had to buy BT 5.0 compatible transmitter. I have no idea why it didn't worked with the old one.
@@pandaengineering this device is also BT 5.0 right?
@trext888 these two (if I remember correctly now) were BT 3.0. I don't think the BT version matters that much, since it's all supposed to be backward compatible, I think they might be missing some pairing protocol functions and that was the main cause, seems that name brand headphones are more picky about the transmitter.
My bt600 not working blue led always on, and all...
It appears the headphone port is the only audio out. Not a very sophisticated CD player (Sharp). Wonder if that will work? But I presume that will mute the regular speakers?
Should work just fine, try the lower volumes first. From my expirience it works best at 30-50% of max volume. Most players will disable the speakers once you connect to the headphone jack, but you're right, some need a separate mute.
I am not sure if ALL BT modules only transmit in mono but i have now bought four different modules and they ALL transmit only mono from my stereo laptop. It's strange because my laptop BT card DOES transmit in stereo. If you could put one of them in a case and power it, it would be OK. The modules do sound decent though as they transmit in both ears, just not in stereo. I guess it is because most uses are only mono anyway, like BT speakers, etc.
I've bought recently something similar (although 5x as much expensive) with BT 5.0 support and it works in stereo. Looking at the chip datasheet it seems to be much easier to set it up for mono and I think this is the case here.
@@pandaengineering Thanks for the reply......could you give me a link to the module you bought? I am curious about it...thanks.
..if I had 2 of these could they be paired to itself rx to tx..? Vice versa... For example old walkman to old stereo amplifier within 10 meters wirelessly..
Sure, I did something like that around 3:00
Keep in mind that sound quality won't be great and after I tested those afterwards it's only left channel transmitted as mono on the output (so it plays left channel on both right and left of the output).
@@pandaengineering ..I have bought 2 sorely for that purpose..never test pairing it yet... tq for replying
Want to use it on my non-transmitting CD player and Bluetooth to my Sonos wireless speaker. Will that work? CD player does has USB port.
Usb here is only for powering the device and if it still delivers power to the usb during CD playback it should work fine just fine. Some players only power the USB when plaing from it as source.
The CD player USB does not power the Bluetooth USB. I need a solution to take a CD player w/o transmitter mode Bluetooth to be able to Bluetooth audio to a Sonos wireless speaker. Any suggestions?
If the CD player cannot power the transmitter, you'll have to use another power source. Wall charger or even power bank will work just fine.
@@pandaengineering if I plug Bluetooth device usb into power source how would I connect device to CD player? Where would I plug the 3.5 cord in? I have only 2 options; phones and audio in. Thanks
To phones - it's an audio out.
I have this module and i found it okay. Not the best quality but gets the job done. What irritates me is that i have to press the button to enter 'Receiving Mode' every time i plug it in. Is there a way i can set it by default
?
When I did a mod in this video th-cam.com/video/aaH5h2VdmBo/w-d-xo.html I discovered that if you bridge the switch, it will stay in receiving mode permanenty.
Have you tried forcing the button to be pressed with scotch tape? It shoud work.
Hi, I have a TV that doesn't have Bluetooth built-in, so I bought this one, it doesn't work. Can you please explain that,I search and couldn't find anywhere on the net.
I just wanna use my wireless headphones for the tv.
Thanks...
press and hold the button for 3 seconds to enter 'Pairing mode'
Hello! Can you use this a bluetooth dongle for pc?
No, this is audio only and it's not actually a USB device, it's just USB powered.
Quick one, do it can't install a Bluetooth driver for PC or serve as external Bluetooth?
I'm not looking to use phone as a music source...want to use CD player via Bluetooth to wireless speaker.
Check the player manual, there should be some kind of audio out and there you can connect the transmitter in.
can you connect bluetooth earphones to them?
They have to support at least A2DP profile
What is Ad2p profile?
@davidmike3923 You can think of Bluetooth profiles like device types for USB. Bluetooth is a general protocol, but profile would describe its capabilities. A2DP (Advanced Audio Distribution Profile) is basically what you have in any Bluetooth headphones and speakers that provide higher quality audio (could be mono to stereo and no microphone support). In the early days(and on the extremely cheap end) of Bluetooth there were earpieces supporting only Headset Profile (HSP). These were low quality, mono only but with a microphone to support calls. My Logitech Zone Vibe 100 headphones (even though they are fairly modern) suddenly drop audio quality whenever someone is calling me and this is because it switches audio from A2DP to HSP. Usually modern speakers and headphones support both profiles, but this transmitter seems to be limited to A2DP only with a basic codec (I would expect that it supports SBC codec only).
Y los subtitulos en español????????????
it's stereo ?
No, I tested those later and it transmits and receives in mono 😕
Have no idea how yo work this.
I want to play audio from a laptop to bluetooth earphones.
No set up instructions with the device and no idea how to set it up. I can connect to bluetooth only in Red(Receiver mode) and not in Blue(transmitter mode). Even connected in Red(reciver mode)i cant play music from my phone to the laptop[ sepakers. No idea how to work this cheap chinese contraption!
USB is only used for powering this device so you still need to use the audio jack as an input/output for sound. I used power banks for the video, because it doesn't matter where you plug the devices in. If pressing the little button doesn't change the light color, I think it's possible that you got a receiver only device.
When you will be able to set it into transmitter mode, connect it to headphone out of your laptop and put your headphones into pairing mode.

I've since learned that my old Windows 7 laptop will not function properly with this device because it's just not compatible. Whoever created the device obviously didn't give any comparability thoughts towards older OS.
I've brought an MPow 4.0 as they have drivers for XP/Vista/Win7,8,10 32/64bit
@@SHIPIT01 I see you have bought the wrong thing
This BT600 isnt a bluetooth card for pc
fuck the what is he trying to do.
