With the increasing popularity of trams, it is gradually becoming a new favorite for young people to travel. In this booming trend, 

as an indispensable energy supply station for trams, the convenience and efficiency of charging piles have become the focus of business.

 In order to meet the needs and preferences of young people, businesses need to constantly optimize the charging pile service, integrate

 more intelligent and personalized elements, so that young people can enjoy the environmental protection and fashion brought by the

 tram, and also experience seamless and fast charging service, so as to further promote the prosperity and development of the tram market.

Communication method: Bluetooth HID

Connection method:

HID mode

HID mode means that in the case of no APP, the phone's built-in Bluetooth is used to connect to the module, and the connection is 

completed after entering the PIN code. The second time you approach can connect, without searching. The maximum number of HID

 connections can be up to five, beyond which the previously matched device will be replaced, starting from the earliest device.

BLE mode

APP is needed to connect with the module to control the charging pile. The pre-bound Bluetooth data of the charging pile is used to 

autonomously search and identify the Bluetooth signal of the charging pile. By automatically checking the PIN code, the program will 

quickly establish a connection. If the user approaches the charging pile a second time, the entire process will not require any manual 

operation, and the app will automatically complete the connection with the charging pile Bluetooth.
