Porting the Bluetooth protocol stack and its tools to embedded ARMLinux

Currently, Bluetooth technology is mature, especially for mobile phones and PCs. This article mainly describes Bluetooth file transmission based on embedded armlinux. Currently, Linux kernel 2.6.x has been integrated with the bluez Bluetooth driver. For kernel version 2.4, download and install the bluez Bluetooth driver from the official bluez website.

Currently, Bluetooth technology is mature, especially for mobile phones and PCs.

This article mainly describes Bluetooth file Transmission Based on Embedded arm linux.

Currently, Linux kernel 2.6.x has been integrated with the bluez Bluetooth driver. For kernel version 2.4, download and install the bluez Bluetooth driver from the official bluez website.

This is based on the 2.6 kernel. For 2.4, download bluez and install it. With the bluez Bluetooth driver, you also need to install the bluez-libs Library and the bluez-utils tool.

Bluetooth File Transfer Application Development is divided into two parts: On pc and on ARM.

Configuration in linux

Fedora 9

Kernel version 2.6.25

Gcc: 4.0.0

There are always many problems when using a new kernel version for embedded development. 2.6.11 kernel is suitable for embedded development.

First, install the bluez-libs library and bluez-utils tool on the pc.

1. Download bluez-libs and bluez-utils from the official bluez website.

Http://www.bluez.org/download/

I downloaded bluez-libs-3.36 and bluez-utils-3.36.

2. Compile the Linux kernel of the PC

1. # Cd/usr/src/kernels/2.6.25-14. fc9.i686/
2. # Make menuconfig
3. Networking -->
4. Bluetooth subsystem support -->
5. L2CAP protocl support
6. SCO links support
7. RFCOMM protocol support
8. [*] Rfcomm tty support
9. BENP protocol support
10. [*] Multicast filter support
11. [*] Protocol filter support
12. CMTP protocol support
13. HIDP protocol support
14. Bluetooth devices drivers -->
15. Hci usb driver

3. Install libs and utils.

Libs and bluez have to be installed normally by installing linux software.

Install libs

1. # Tar xzvf bluez-libs-3.36.tar.gz
2. # Cd bluez-libs-2.25
3. #./Configure
4. # Make
5. # Make install

Note: If you use fedora 9 or the kernel version 2.6.25 or later, some files or parameters are not defined when utils is installed.
