I have now got the parts detailed in my previous post and have got the Bluetooth Transmitter working with a pair of Bluetooth Noise Cancelling Headphones,
There are TWO Gotchas that you need to beware of:
- The Bluetooth Transmitter CANNOT be powered from one of the RPi USB Ports NOR can it be powered from the same 5V source that powers the RPi. If I attempt to do this, it immediately kills the WiFi adapter connection and kills Volumio operation. It works fine if poweredfrom a separate USB Mains adapter connected to a separate Mains Socket,
Just for clarification, this is not because of proximity to the WiFi Adapter. I have tried keeping them over a Metre apart but it will not work if connected to the same 5V source as the RPi
- Because the Bluetooth Transmitter is a “headless” device, it will not pair with a client that requires a PIN code to be entered in the pairing process. I have a Bluetooth Speaker which requires a PIN 1234 and I have no way of pairing that. Fortunately the Bluethooth Headset pairs without a PIN Code.
I hope this helps anybody else treading this path - Robin
