I have a custom board which has HCI_TX, HCI_TX, GND and VDD pins. How do I see the trace output using these pins (I use a FTDI USB to TTL adapter) for debugging? What configuration changes/initializations do I need to do?
I don't know how your custom board is configured, but here is an example from an example board with switch settings:
JLINK is a debugger that we use but you need to switch BCM_RX and BCM_TX from the chip to the HCI config.
