# BTstack Port for POSIX Systems with NXP/Marvel H4 Bluetooth Controller
|
||
|
|
|
||
|
|
## Configuration
|
||
|
|
Most Bluetooth Bluetooth Controllers connected via UART/H4 require some special configuration, e.g. to set the UART baud rate, and/or require firmware patches during startup.
|
||
|
|
In this port, we've show how a NXP/Marvell Controller can be configured for use with BTstack. It's unclear if the required firmware file for older Controllers,
|
||
|
|
e.g. 88W8997, can be detected during the firmware upload. This port selects the firmware for NXP 88W8997.
|
||
|
|
For newer Controllers, e.g. IW416 or IW612, the firmware can be selected automatically.
|
||
|
|
|
||
|
|
## Compilation
|
||
|
|
|
||
|
|
BTstack's posix-h4-nxp port does not have additional dependencies. You can directly run cmake and then your default build system. E.g. with Ninja:
|
||
|
|
|
||
|
|
mkdir build
|
||
|
|
cd build
|
||
|
|
cmake -G Ninja ..
|
||
|
|
ninja
|
||
|
|
|
||
|
|
## Running the examples
|
||
|
|
|
||
|
|
Please reset the Controller first. On start, BTstack prints the path to the packet log.
|
||
|
|
|
||
|
|
$ ./gatt_counter
|
||
|
|
Packet Log: /tmp/hci_dump.pklg
|
||
|
|
BTstack counter 0001
|
||
|
|
BTstack up and running on 00:1A:7D:DA:71:13.
|
||
|
|
|
||
|
|
## ToDo
|
||
|
|
- increase baud rate for firmware upload
|
||
|
|
- skip firmware upload if firmware already present
|
||
|
|
- increase baud rate for application
|
||
|
|
- send SCO audio
