Bluetooth-to-3.5 mm that can TX/RX simultaneously? (lemm.ee)

submitted 1 year ago by [email protected] to c/techsupport

3 comments fedilink hide all child comments

I need to adapt a Bluetooth headset (speakers + mic) to 3.5 mm, but the only adapters I can find will either transmit or receive, not both at the same time. Is there some technical limitation why this can't be done, or is there just no market for such a device? Thanks.

standard 3.5mm cannot do both, the specification you could try looking for is 4 conductor 3.5mm...

They're also often called TRRS (for 4 pole), in relation to TRS (3 pole).
