Bluetooth: Add custom "monitor" protocol logging over UART (264c207f) · Commits · Wenxi XU / zephyr

With most boards there's no simple way to get access to the HCI traffic. Simultaneously these boards only have one external UART for the console. This patch introduces a protocol which combines both normal logs and HCI logs over a single binary protocol sent over the console UART. The protocol is modeled based on the btsnoop/monitor protocols used by BlueZ, and the first tool that's able to decode this is btmon from BlueZ ("btmon --tty <tty>"). For platforms with two or more external UARTs it is still possible to use CONFIG_UART_CONSOLE as long as the UART devices used are different, however on platforms with a single external UART UART_CONSOLE should be disabled if BLUETOOTH_DEBUG_MONITOR is enabled (in this case printk/printf get encoded to the monitor protocol).
