If you need to reprint or use it for commercial purposes, you must obtain the author's consent and indicate the source Main functions Use mobile phone APP to operate the rolling door (the rolling door motor needs to have its own limit switch), rise, pause, fall, lock, and unlock. The APP includes two devices, Android and IOS. The APP comes with a gesture password (directly transplanted from the open source project) The data communication between the APP and CC2541 uses AES128 encryption, in which the secret key is dynamically generated at each connection. Use rtc as a random seed to generate a string of data, and then generate a secret key from the random number in a specific way. The device has a built-in log saving function (using SNV to save), which can save 136 door opening logs. It is intended to be used as a clock-in function. It records when the door is opened and when it is closed. Therefore, the number of logs that can be saved is not large, and only one month of records is considered. The log display shown in the figure below has been implemented in the Android APP, but it has not yet been implemented on IOS.

Actual display effect on Android

It supports adding up to 16 APP device permissions. You can enter the management interface with the administrator password, increase or decrease permissions at any time, and permissions support alias settings. (To enter the management interface, you must have an actual device connection)

In China, rolling shutter doors do not require 3C certification.

This needs a careful look.

Well, OK, I thought all circuit boards with electricity would have to be certified.
