bluetooth stack

From: Http://www.developer.com/ws/other/article.php/10949_3640576_3 By Alex Gusev Few general words The previous article, "experiencing this mysterous Bluetooth Stack programming," gave you a very brief overview of the widcomm BT stack and how to manage it from your own applications. now, you switch to yet another Implementation of

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

 Bluetooth 4.0/ble protocol Stack Learning notes (i) Required Software tools: 1. BLE protocol stack (ble-cc254x-1.4.0) 2. IAR development software (IAR Embedded Workbench8.20.2) Note: The 1.4.0 protocol stack uses the 8.20.2 version of IAR, the 1.3.2 protocol stack, etc.,

Recently in the porting QQ IoT protocol, you need to read the device MAC address.Read the CC2541 device MAC address method, there is a direct read Mac register, you can also call the protocol stack API. This takes the form of a call API.1 /*use the protocol stack API to read MAC addresses*/2 StaticUint8 macaddr[b_addr_len]={0};//MAC address3uint8_t macstr[ -] = {0};4 5 Gaprole_getparameter (gaprol

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 drive

specification (TCS). L2cap Complete data Disassembly, service quality control, protocol multiplexing and group extraction, is the basis of other upper layer protocol implementation, so it is also the core part of Bluetooth protocol stack. SDP provides a mechanism for upper-level applications to discover the services and their characteristics that are available on the network. At the top of the

Bluetooth 1.2 vs 1.1: 1. Adaptive Frequency Hopping (AFH ):Adaptive Frequency Hopping TechnologyThe main function is to reduce interference problems between Bluetooth products and other wireless communication devices. 2. Extended synchronous connection-oriented links (ESCO ):Extended synchronous link-oriented channel technologyIt is used to provide audio transmission with high QoS, and can further meet the

Specification version 3.0), The core of Bluetooth 3.0 is the "Genericalternate mac/phy" (AMP), a new alternate RF technology that allows the Bluetooth protocol stack to dynamically select the correct RF for any task. The technologies originally expected to be used in the new specification included 802.11 and UMB, but the UMB application was eliminated in the new
