Description

Transmission steps of tire pressure detector Bluetooth transmission system

The invention relates to the transmission steps of a bluetooth transmission system of a tire pressure detector, and includes the upgrade process of the firmware of the tire pressure detector and the method of obtaining the firmware package.
