Description
Bluetooth is a wireless technology standard used for exchanging data between fixed and mobile devices over short distances using short-wavelength UHF radio waves in the industrial, scientific and medical radio bands, from 2.400 to 2.485 GHz, and building personal area networks (PANs).
A Bluetooth module is usually a hardware component that provides a wireless product to work with the computer or in some cases the bluetooth may be an accessory, peripheral, a wireless headphone or other products (such as cellphones can use).
The Bluetooth module can receive and transmit the data from a host system with the help of the host controller interface (HCI).
BT-20 Bluetooth Module cc2640 BLE5.0 Serial Port Transfer Support High-Speed OTA Air Upgrade.
This module supports the UART interface and supports Bluetooth serial port transparent transmission. It has the advantages of low cost, small size, low-power consumption, high sensitivity of sending and receiving, etc.
It can realize its powerful functions with only a few peripheral components simple operations, high-cost performance and technology leading edge.
Bluetooth 5.0 BLE Module: Compared to the Bluetooth 4.0 module, this module has a faster transfer rate and a larger MTU.
You quickly integrate this module into your project.
