The Bluetoothkit is a powerful Android Bluetooth communication framework that supports connection communication, Bluetooth broadcast scanning, and beacon resolution for low power Bluetooth devices.For detailed documentation on this project, please follow: https://github.com/dingjikerbo/BluetoothKitFor beginners just contact with Android Bluetooth development, will often encounter some strange pits, I also walked all the way, I met some of the pits summed up a bit, these pits in this project are

For research and development and testing BLE , often see the same name of the device, is extremely inconvenient, a large pile of equipment at the same time the Power will let colleagues do not know which device is what they really want to operate the target. Again millet bracelet, home has three millet bracelet, open the device search is all "MI", do not know which one to connect, so in the beginning of the use of the user to call the ring a few times

ble-nrf51822 Tutorial 5-Static password settings Nordicble Exchange Group 498676838This talk introduces some relevant theoretical knowledge of pairing, and describes how to implement the "Static password" setting The program is based on the UART demo under sdk9.0 In addition, the mobile app used in the test is lightblue under iOS. The exact phrase here should be called the pairing code, not the password. Enter this pairing code as an optional part o

A few days ago, something happened. When I went to work in the morning, I took the key of my daughter-in-law and we couldn't lock the door without the key. So when my daughter-in-law was about to leave, she couldn't lock the door, so she had to call me. At that time, I had already arrived at Huo camp. Well, I had to go back and give my daughter-in-law the key. Then I was late for work both of them, I am also very depressed. This is a hot day! I have been learning

BrieflyThe aerial package format of the link layer should be the basic unit of all packages based on the other layers on the ble Link layer, so it is necessary to have an understanding of the rest of the package, and to analyze the basics of the Bluetooth protocol through the aerial package.Aerial package formatFirst Look at:This is the Bluetooth BLE air packet in the overall format.Preambleheader, used to

Briefly SMP is the security Manager Protocol. Its content is mainly pairing and key distribution, and then using key to the link or data encryption. Reference Articles Before you understand the SMP protocol, you need some prior knowledge of BLE security management to refer to:Introduction to the SMP security management of BluetoothPairing method of Bluetooth security management SMSafe l2cap Channel of Bluetooth security management

1. Fatal error: Fatal error[e72]: Segment blenv_address_space must be defined in asegment definition option (-Z,-b or-p) The cause of this error is a problem with the configuration of the IAR project.

But I think it might be a supplement to the public address.This is the private address of the resolvable, the Prand part is a randomly generated 24bit value, the hash portion is generated using the following method:hash = ah(IRK, prand)Ah is an SMP part of the random address generation function, Irk is the key (Identity resolving key), the first randomly generated prand part, and then use this algorithm to generate the hash, and then the hash and Prand part into the corresponding bit reg
