- the schematics do not appear to label the chips - there is a documented led called 'BT_ON' that purportedly lights when bluetooth is powered. this string does not appear to be present in the raspi 4 schematics. It's strange I'm having trouble finding this. The raspberry pi 3 bluetooth chip is clearly documented at https://www.raspberrypi.org/products/raspberry-pi-3-model-b/ : BCM43438 wireless LAN and Bluetooth Low Energy (BLE) on board It's possible the pi 4 uses the same chip. It's a bcm43xx .
