I tried looking but couldn't find anything on an idea I had. I was working on a repeater for my vehicle. Basically making a wifi Hotspot that all of my devices (dash cam, obd reader, rear view camera, media controller, etc) could all connect to. I wanted to do this because they could stay constantly connected, meaning that they wouldn't have to reconnect every time I turn my phones tether on. Then I realized the repeater would still have to connect to my phone, so whenever I entered my vehicle, to receive the data, I had to turn on Hotspot, which also takes time. I don't want the hassle of having to turn it on and off. Then I wondered, would it be possible to used my Bluetooth tether (which I can leave on at all times without screwing my battery), to connect a pi to the internet, and then have the pi broadcast a wifi signal. I've been looking, but haven't found any good leads.
