BTstack port for Zephyr Controller with HCI UART Firmware Connectected To POSIX System
The main difference to the regular posix-h4 port is that that the Zephyr Contoller uses 1000000 as baud rate. In addition, the port defaults to use the fixed static address stored during production.
Prepare Zephyr Controller
Please follow this blog post about how to compile and flash samples/bluetooth/hci_uart to a connected nRF5 dev kit.
In short: you need to install an arm-none-eabi gcc toolchain and the nRF5x Command Line Tools incl. the J-Link drivers, checkout the Zephyr project, and flash an example project onto the chipset:
-
Get nrfjprog as part of the nRFx-Command-Line-Tools. Click on Downloads tab on the top and look for your OS.
-
Checkout Zephyr and install toolchain. We recommend using the arm-non-eabi gcc binaries instead of compiling it yourself. At least on OS X, this failed for us.
-
In samples/bluetooth/hci_uart, compile the firmware for nRF52 Dev Kit
$ make BOARD=nrf52_pca10040
-
Upload the firmware
$ make flash
-
For the nRF51 Dev Kit, use
make BOARD=nrf51_pca10028.
Configure serial port
To set the serial port of your Zephyr Controller, you can either update config.device_name in main.c or
always start the examples with the correct -u COMx option.
Toolchain
The port requires a Unix-like toolchain. We successfully used mingw-w64 to compile and run the examples. mingw64-w64 is based on MinGW, which '...provides a complete Open Source programming tool set which is suitable for the development of native MS-Windows applications, and which do not depend on any 3rd-party C-Runtime DLLs.'
We've used the Msys2 package available from the downloads page on Windows 10, 64-bit and use the MSYS2 MinGW 64-bit start menu item to compile 64-bit binaries.
In the MSYS2 shell, you can install everything with pacman:
$ pacman -S git
$ pacman -S make
$ pacman -S mingw-w64-x86_64-toolchain
$ pacman -S python
$ pacman -S winpty
Compile Examples
$ make
Note: When compiling with msys2-32 bit and/or the 32-bit toolchain, compilation fails
as conio.h seems to be mission. Please use msys2-64 bit with the 64-bit toolchain for now.
Run example
Just run any of the created binaries, e.g.
$ ./le_counter
The packet log will be written to /tmp/hci_dump.pklg
