 ## Debug output
 
-All debug output can be either send via SEGGER RTT or via USART2. To get the console from USART2, connect PA2 (USART2 TX) of the Discovery board to an USB-2-UART adapter and open a terminal at 115200.

 In src/btstack_config.h resp. in example/btstack_config.h of the generated projects, additional debug information can be enabled by uncommenting ENABLE_LOG_INFO.
 
-Also, the full packet log can be enabled in src/port.c by uncommenting the hci_dump_init(..) line. The console output can then be converted into .pklg files for OS X PacketLogger or WireShark by running tool/create_packet_log.py

 ## GATT Database
 In BTstack, the GATT Database is defined via the .gatt file in the example folder. During the build, the .gatt file is converted into a .h file with a binary representation of the GATT Database and useful defines for the application.
