Application of Bluetooth Solution in car diagnostic instrument

With the improvement of people's quality of life, the rapid development and widespread popularity of automobiles, more and more people begin to have their own cars, car maintenance and repair have become more and more important.


During the time of using the car, it is inevitable that there will be large and small failures, and most car owners do not understand the car failures, nor can they deal with them in a timely and effective manner. Usually, they can only go to a special car repair shop or 4S shop. When a breakdown occurs in suburban or long-distance roads, it can cause a lot of trouble.


In addition, when the vehicle has an abnormal electronic circuit or an electronic control unit (ECU) failure, although it can continue to drive, it will bury hidden dangers for driving safety. In order to solve the above problems, some companies have developed a portable diagnostic device based on Bluetooth wireless communication technology, which can conveniently and quickly help car owners carry out vehicle fault detection and ensure driving safety. Insert the diagnostic device into the OBD interface of the vehicle. The Bluetooth module in the diagnostic device is connected to the Bluetooth of the mobile phone. The current vehicle status, such as engine speed, brake fluid, fuel volume, etc., can be viewed through the mobile APP.


Moreover, it can complete driving data collection, OBD fault code self-collection, OBD vehicle data collection, etc. It can accurately find the fault point for the owner, so as to find the repair and treatment method as soon as possible. In some specific places, such as a vehicle parked in the parking lot, and then the collected fault information needs to be transmitted to the office computer, this requires a long-distance Bluetooth module, the OBD end is directly plugged into the vehicle, and the other end passes through a long-distance Bluetooth module is connected to the R232 serial port board, and then directly plugged into the computer through a DB9 data plug, and the fault data information collected by the OBD can be received on the computer side.


Shenzhen Feasycom Technology Co., Ltd. focuses on Bluetooth, Wi-Fi, and other IoT wireless modules, and is in the leading position in the field of Bluetooth data transmission, especially in applications that require long-distance, dual-mode data transmission. Hereby recommend two Bluetooth data transmission modules suitable for application in car diagnostics:
