[0049] Working principle: Please refer to Figure 11 , the battery powers the NRF52832 module and the color reflective screen. The external Bluetooth device communicates wirelessly with the Bluetooth circuit on the NRF52832 module, and transmits the information to the main control circuit on the NRF52832 module through the Bluetooth circuit. The main control circuit controls the refresh display of the color reflective screen through the SPI protocol.

[0050] Working mode: Select the text information and / or image information to be transmitted in the pre-installed program of the electronic device with Bluetooth function. Then, place the pendant within the range of the Bluetooth signal connection of the electronic device for connection. After successful connection, click the send instruction in the original program to send the selected information to the pendant for display. When the Bluetooth connection of the pendant is successfully disconnected or there is no connection within the set time, the pendant will enter the sleep state. At this time, the pendant operates with extremely low power consumption, and the content displayed on the pendant is the content displayed last before the pendant goes to sleep. When the user manually presses the button on the back of the pendant, the pendant will be awakened and enter the editable state. At this time, the external Bluetooth device can communicate with the Bluetooth of the pendant again and modify the content displayed on it.
