# Experimental port of BTstack to Zephyr running on Nordic nRF5 Series
|
|
|
|
## Overview
|
|
|
|
This port targets the bare Nordic nRF5-Series chipsets with the BLE Link Layer provided by the Zephyr project.
|
|
|
|
## Status
|
|
|
|
Working with nRF52 pca10040 dev board. Public BD ADDR is set to 11:22:33:44:55:66 since the default 00:00:00:00:00:00 is filtered by iOS.
|
|
|
|
## Getting Started
|
|
|
|
To integrate BTstack into Zephyr, please move the BTstack project into the Zephyr root folder 'zephyr'.
|
|
|
|
Then integrate BTstack:
|
|
|
|
cd /path/to/zephy/btstack/port/nrf5-zephyr
|
|
./integrate_btstack.sh
|
|
|
|
Now, the BTstack examples can be build from the Zephyr examples folder in the same way as other examples, e.g.:
|
|
|
|
cd /path/to/zephyr/samples/btstack/le_counter
|
|
make
|
|
|
|
to build the le_counter example for the pca10040 dev kit using the ARM GCC compiler.
|
|
|
|
You can use `make flash` or `./flash_nrf52_pca10040.sh` to download it onto the board.
|
|
|
|
All examples that provide a GATT Server use the GATT DB in the .gatt file. Therefore you need to run ./update_gatt_db.sh in the example folder after modifying the .gatt file.
|
|
|
|
This port does not support Data Sources aside from the HCI Controller.
|
|
|
|
## TODO
|
|
- printf is configured by patching `drivers/serial/uart_nrf5.c' to use 115200 (default: 100000). There should be a better way to set baud rate.
|
|
- enable/configure DLE for max packet size for LE Streamer
