-------------------------------------------------------------------------------- /pico_w/bt/README.md: -------------------------------------------------------------------------------- 1 | # Pico Bluetooth Examples 2 | 3 | The source for most of the Bluetooth examples is stored in `pico-sdk/lib/btstack/example`. 4 | There's a standalone example in `pico-examples/pico_w/bt/standalone`. 5 | 6 | ## Debugging 7 | 8 | To debug Bluetooth issues you can enable [btstack](https://github.com/bluekitchen/btstack) debug output which also enables packet logging. 9 | Define `WANT_HCI_DUMP=1` in your CMakeLists.txt file. Uncomment this line to enable debug in the btstack examples. 10 | 11 | target_compile_definitions(picow_bt_example_common INTERFACE 12 | #WANT_HCI_DUMP=1 # This enables btstack debug 13 | ) 14 | 15 | ## Packet logging 16 | 17 | To view packet logs, save the output from the debug port (e.g. the uart) to a file and afterwards run `pico-sdk/lib/btstack/tool/create_packet_log.py `. 18 | This will generate a file with the same name except for a `pklg` extension. This can be opened in the [Wireshark](https://www.wireshark.org) application to analyze communications activity. 19 | 20 | ## Link keys 21 | 22 | By default, the last two sectors of flash are used to store Bluetooth link keys and this relies on the Bluetooth address. Old pre-release versions of the SDK had issues with some devices using a default Bluetooth address. If you experience issues with pairing try Resetting flash memory, see https://www.raspberrypi.com/documentation/microcontrollers/raspberry-pi-pico.html#resetting-flash-memory 23 |
