In a BLE development project, I use TI's CC2541 bluetooth ble SoC, in order to prevent the master-slave device connection disconnection data loss, the hardware added an EEPROM, when the Bluetooth connection, through the notify to the host, but when the Bluetooth connection i

performing a reset. The reset command can preempt execution of other commands. 8.2 Read Device Address The host reads the device address by sending the read BD_ADDR command to the controller. The latter returns a command complete event that contains a fixed device address. If the controller does not have a fixed address, the full 0 address 00:00:00:00:00:00 is returned. At this point, the host needs to generate a random address for the controller, otherwise the data ca

Last year, noridc developed a chip that integrates Bluetooth 4.0 and can communicate with 24l01. The film encapsulation can be very small, and the power consumption is very low. It is very suitable for wearable devices, so I recently had a set of second-hand ak ii and no becon board. I first played some basic peripherals, And now I started to develop ble. Under the official SDK directory, we can find the pr

This article from http://blog.csdn.net/hellogv/, reference must indicate the source! Last time I talked about communication between Android phones and BLE terminals, and the most common BLE terminal should be the iBeacon base station proposed by Apple. IBeacon is based on BLE. It is characterized by sending messages externally through broadcasting. Mobile phones

The previous article describes the communication between the Android phone and the BLE terminal, while the most common ble terminal should be the ibeacon base station advocated by Apple. Ibeacon technology based on BLE, it is characterized by the broadcast of external messages, mobile phones do not need to connect to the Ibeacon base station can also obtain its i

The program is a uart demo Based on sdk9.0 In addition, the mobile app used for testing is lightblue in IOS. The correct statement here should be a pair code, not a password. Enter this pair code as an optional part of the pairing process. Before intr

Turn from: Http://www.wowotech.net/bluetooth/ble_connection.html#comments1. ObjectivePeople who know about Bluetooth know that in classic Bluetooth, staying connected (Connection) is a fairly resource-intensive (power and bandwidth) process. In particular, when there is no data transfer, the resources consumed are completely wasted. Thus, for many

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
