Bough Electronic Science and technology

Bough Technology Company Limited is a member of the Bluetooth organization
SIG is a Technology Association, which is composed of Telecom, computer, industrial automation and network. The team is dedicated to the development of Bluetooth wireless technology, which is the core of low power consumption (Energy 4.0BLE.), which can be used in medical care, physical fitness, smart home, smart home, smart home, smart home, and so on. 

Bough released Bluetooth 4.0 low power module BG330 series
BG330 Bough series low power series modules integrated with a number of Profiles and Serices protocol stack, and IOS, Android, Windows8, smart phones connected to the terminal products, smart and low power consumption of the advantages of rapid and highly recognized by the majority of manufacturers.System based on Center (central equipment) and Peripheral (outside) to connect, data communication.BLE connection process by Peripheral to send data to let any Center know it is a connected device. Data content contains device address, also can contain some additional data, such as the device name, service ID and other.Center received data sent to Peripheral, Peripheral return scan response to Center, so Center will know that this is a connected device.Center can send a request to set up a data connection to the Peripheral paired connection, can also bind operation. Paired connection after the completion of Center and Peripheral for data communication. Bluetooth 4 BLE technology uses 3 channel radio channels, allowing the millisecond time fast connection, efficiency is much higher than the traditional way of channel 32 Bluetooth Bluetooth 79. The traditional data channel, channel spacing is 1MHz; Low Power Bluetooth design only 40 data channels, channel spacing is 2MHz. traditional peak current work of Bluetooth is generally 35mA, the sleep state is working current peak current 0.01mA. and Bluetooth low energy is less than 20mA, 0.004mA. is the current state of sleep.
