I’m noticing a stark decline in the quality of bluetooth products lately (interference, disconnecting, dubious sound quality), and I’m curious if I can figure out what’s going on.
Are there any good books for learning about the Bluetooth technology used in generic PS4 controllers? I’m not sure if that’s bluetooth LE or classic or 5.0, but that’s where I would like to start.
Any books or online resources just to get my foot in the door would be greatly appreciated.
I don’t know of a holy grail, but loading up cli Bluetooth tools like what’s included with bluez, like gatttool (yes, 3t’s), really helped me understand it.
Have a look at “develop your own bluetooth low energy applications for raspberry pi, esp32 and nrf52 with python, arduino and zephyr” by Koen Vervloesem. Typing on mobile so please forgive any errors.
