I was wondering if somebody already tried to create some sort of Bluetooth repeater or bridge? I know they are not the same, but both systems should work for my needs.
In detail, I am trying to create a bridge like this:
|Device_A| | | Bluetooth link | |RPI_A| I I WiFi/ Ethernet link I |RPI_B| | | Bluetooth link | |Device_B|
RPI_B could be combined to
RPI_C to form a repeater instead of a bridge.
However, I could not find any solutions. To my knowledge, there are - if any - only expensive bridges/repeaters. So I thought I could either use the internal Bluetooth chip on the Raspberry Pi 3 or buy some cheap Bluetooth dongles and build a bridge.
Does anybody have helpful hints on how to tackle this problem or has done this before? My guess is that I can not simply get the input of one Bluetooth dongle and transmit it to another Raspberry.
