I am working on a handsfree kit for a handheld radio at the moment and ideally want to use a standard Bluetooth headset for the microphone. The reason I want to use this headset is that it has very good noise cancelling and when used with a mobile phone, most people cannot tell I am even driving. But how can I get the audio from this? There are plenty of cheap Bluetooth receivers that I have found, such as https://www.ebay.co.uk/itm/3-5mm-Wi...dio-Music-Receiver-Adapter-Cable/264359130849 but this is designed to pair to a device like a phone or tablet which can select the Bluetooth receiver. If I put both the headset and the receiver into pairing mode, they are not going to pair. Would appreciate any thoughts. 73 de M0LXQ.
