1*410be61aSMatthias Ringwald# BTstack port for Zephyr Controller with HCI UART Firmware Connectected To POSIX System 26807484cSMatthias Ringwald 3*410be61aSMatthias RingwaldThe main difference to the regular posix-h4 port is that that the Zephyr Contoller uses 1000000 as baud rate. 4*410be61aSMatthias RingwaldIn addition, the port defaults to use the fixed static address stored during production. 56807484cSMatthias Ringwald 6*410be61aSMatthias Ringwald## Prepare Zephyr Controller 7*410be61aSMatthias Ringwald 8*410be61aSMatthias RingwaldPlease follow [this](https://devzone.nordicsemi.com/blogs/1059/nrf5x-support-within-the-zephyr-project-rtos/) blog post about how to compile and flash `samples/bluetooth/hci_uart` to a connected nRF5 dev kit. 9*410be61aSMatthias Ringwald 10*410be61aSMatthias RingwaldIn 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: 11*410be61aSMatthias Ringwald 12*410be61aSMatthias Ringwald * Install [J-Link Software and documentation pack](https://www.segger.com/jlink-software.html). 13*410be61aSMatthias Ringwald * Get nrfjprog as part of the [nRFx-Command-Line-Tools](http://www.nordicsemi.com/eng/Products/Bluetooth-low-energy/nRF52-DK). Click on Downloads tab on the top and look for your OS. 14*410be61aSMatthias Ringwald * [Checkout Zephyr and install toolchain](https://www.zephyrproject.org/doc/getting_started/getting_started.html). We recommend using the [arm-non-eabi gcc binaries](https://launchpad.net/gcc-arm-embedded) instead of compiling it yourself. At least on OS X, this failed for us. 15*410be61aSMatthias Ringwald 16*410be61aSMatthias Ringwald * In *samples/bluetooth/hci_uart*, compile the firmware for nRF52 Dev Kit 17*410be61aSMatthias Ringwald 18*410be61aSMatthias Ringwald $ make BOARD=nrf52_pca10040 19*410be61aSMatthias Ringwald 20*410be61aSMatthias Ringwald * Upload the firmware 21*410be61aSMatthias Ringwald 22*410be61aSMatthias Ringwald $ make flash 23*410be61aSMatthias Ringwald 24*410be61aSMatthias Ringwald * For the nRF51 Dev Kit, use `make BOARD=nrf51_pca10028`. 25*410be61aSMatthias Ringwald 26*410be61aSMatthias Ringwald## Configure serial port 27*410be61aSMatthias Ringwald 28*410be61aSMatthias RingwaldTo set the serial port of your Zephyr Controller, you can either update config.device_name in main.c or 29*410be61aSMatthias Ringwaldalways start the examples with the `-u /path/to/serialport` option. 30*410be61aSMatthias Ringwald 31*410be61aSMatthias Ringwald## Compile Examples 326807484cSMatthias Ringwald 336807484cSMatthias Ringwald $ make 346807484cSMatthias Ringwald 35*410be61aSMatthias Ringwald## Run example 366807484cSMatthias Ringwald 37*410be61aSMatthias RingwaldJust run any of the created binaries, e.g. 38*410be61aSMatthias Ringwald 39*410be61aSMatthias Ringwald $ ./le_counter 40*410be61aSMatthias Ringwald 41*410be61aSMatthias RingwaldThe packet log will be written to /tmp/hci_dump.pklg 42*410be61aSMatthias Ringwald 43
