2、 Bluetooth chip selection
The Bluetooth Solution Development Engineer analyzed the development solutions of the commonly used electric vehicle Bluetooth speakers in the market, and assessed that the ac6955f4 qsop24 model of the Jerry ble Bluetooth chip series can be used as the main control chip.
3、 Working principle
The Bluetooth audio of electric vehicles is to connect and play the content you want with Bluetooth devices such as tablet computers and mobile phones. Its power consumption is very low and its propagation speed is very fast. Because of one-to-one transmission, its confidentiality is good.
The above is the development content of the Bluetooth speaker solution for electric vehicles shared by the Bluetooth solution development engineers. Our company has focused on the development of MCU application solutions for 15 years, focused on the development of Bluetooth intelligent control chip application solutions, and is committed to developing creative intelligent products that are more in line with the market user experience.
