We tend to thing new is better but strangely not with wifi!
Trying to downsize (litterally) our tv RF transmitter and headphones ,both work fine but bulky so i thought bluetooth ,we both have headphones hooray easy peasy the bluetooth ones are so modern should be better!

Why on earth was bluetooth invented? Its crap !
Seemingly in my case you cannot connect 2 headphones to one transmitter (as many as you like with RF if on same channel)

Even stranger is the inability even to connect a phone to a watch and listen to music !

Anyone know of a dual channel transmitter IE a dongle you plug in a tv and two people can listen at once or are our ancient RF versions superior?

Perhaps theres RF versions the size of blutooth ones for 99p

Here Chesters1,

 

I DIDN'T READ IT

 

It is possible within the Bluetooth specification to have a Bluetooth master device connected to multiple slave devices, but there are limits:

     > Prior to Bluetooth spec. rev. 4.1, Slave devices could only be connected to a single piconet at a time. The reason for this is because when the connection is initiated, the advertising device must synchronize it's clock to that of the initiator. So, a slave device cannot be synchronized to two independent free-running clocks at the same time, hence the one master per slave limit. Bluetooth 4.1 addresses this, so a slave device can be connected to two piconets simultaneously, however I don't know the exact details of how.

     > The Bluetooth device you're using must be running a stack that  supports multiple concurrent connections. Many Bluetooth stacks do support this, but there is a limit on how many devices can be connected at the same time, and the limit is usually related to the amount of memory available on the Master device.

     > The type of connection you're using must allow for multiple instances of that connection on a piconet. This is easiest to explain by example. You can only have a single Bluetooth audio connection for music streaming. The reason for this is that the A2DP profile for audio streaming is designed to have only a single connection active at a time. So you cannot connect your smartphone to two Bluetooth speakers at the same time. 

Given all that, you also need an interface to the Bluetooth device that allows you to setup multiple connections. So while this may all be theoretically possible, if the devices interface/software was not designed to allow for  two connections at a time, you're out of luck.

This might be the solution chesters??

 

Or google a bluetooth splitter??

 

Could try this first though.

Companies want the "GREAT UNWASHED" to pay twice for the pleasure when in fact (with a bit of clever play) can get away with just the once!!

Yikes bit pricy i may have to frequent street corners !
I will look into other versions to see if they are cheaper at source ,cheers
Perhaps they will work on my detector? Wink

Low latency is needed ofcourse ,bluetooth is incredibly slow so using a normal transmitter on a tv means the audio has a big lag so the mouths dont line up with what they are saying (no problem with RF) its even worse on a detector you dig holes 6" from the coin lol

DOH found the transmitter cheaper but to use it you need low latency headphones as well ,i will stick to rf!
