Because of the functional requirements of the project, you need to port the bluez Bluetooth protocol stack to the S3C2410 development platform. Many problems occur during the transplantation process, such as the version mismatch of the dependent library, the cross-compiler version is too high or too low. In order to reduce the migration detours, We will summarize the combined version and compilation process

All along, Android support for Bluetooth is very confusing, can be said to be a lump of shit. Each version of the protocol stack is different, the earliest use of BlueZ, into the 4.x era, replaced by Google's own bluedroid. Change it, at least wait for it to be done again, results 4.2, 4.3, 4.4 of the bluedroid are all different. This is to me and other non-professional
In Android, the structure of the Bluetooth system is as follows:In this architecture, the bottom-up sequence is the module driver, the Bluetooth protocol stack, the bluetooth.apk, the framework, and various Bluetooth applications. Among them, the kernel of the driver is directly and hardware to deal with, generally by
At startup, it takes some time to fully load and initialize the Bluetooth protocol stack. You can use bth_namedevent_stack_inited to check the protocol stack initialization, which is defined in % _ winceroot %/public/common/SDK/INC/bt_api.h. To open this naming event, you must use

We have already learned about the principles and circuits of the Bluetooth protocol stack. Now we will introduce the SoC Structure Design for the embedded Bluetooth protocol stack. According to the hardware structure of the above Bluetooth
[DESCRIPTION] in BT2.1 and later versions, the Bluetooth protocol has a new way of simply pairing (simple pairing) in addition to the traditional password pairing (PIN code pairing). This new pairing operation is simpler and more secure. At present, most Bluetooth devices in the market have supported the simple pairing method. From the user's point of view, the t
Development is divided into two parts: On pc and on ARM.

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.

Earlier this year, Microsoft confirmed that it would bring the GATT Server APIs for WIN10 mobile devices, later this year. GATT agreements are important for wearable equipment services, such as smart bracelet, smart watch, etc.
Microsoft employee Clint Rutkas at the end of September that the Bluetooth team is working to add the GATT Server APIs to the WINDOWS10 system and will be open to Win10 Mobile Insider users first, and the SDK is coming this
