My Chromebook has Bluetooth, but as of writing, ChromeOS does not support HSP or A2DP, so I cannot play music or record audio through my Bluetooth wireless headset.
I very much would like to be able to use my headset for something like Hangouts, so I can talk and hear through my heads.
The Chromebook does have a TRRS headset jack, which works just fine, so I figured there'd be a device that could interpret Bluetooth as analog, and vice versa. There do exist many devices that either receive or transmit audio over Bluetooth when plugged into a 3.5mm jack, and some devices that purport to do both, but I have not been able to find a device that can transmit and receive at the same time.
My question for you is thus: does there exist a device that I can buy that will plug into the TRRS jack and be able to connect via Bluetooth to my wireless headset, using HSP or something like that.
Worst case, I could try to hook up a TRRS splitter that's male TRRS to two female TRS and then hook up a Bluetooth transmitter to the audio TRS and a Bluetooth receiver to the mic TRS, and then tell my headset to receive from the former and transmit to the latter, but that will require several pieces of hardware, and I'm not sure if there would be some weird lag between the transmit/receive that would cause calls to be terrible.
