Firmware Design for Location Tags
The location tag does not use RTOS, and "electricians" describe it as "streaking" :).
The location tag can be connected to the computer via USB. We have a tag configuration program that can configure various parameters of the tag. The tag configuration program has a new version of tag firmware built-in, and the tag firmware can be upgraded.
The working principle of the tag is relatively simple. It is usually in a sleep state. After the set time is up, it wakes up, sends a UWB location data packet, and then continues to sleep.
When the button is pressed, the tag will also wake up and immediately wake up to send a UWB location data packet.
The tag is designed with a battery reminder function. When the battery voltage is lower than a certain value, the red LED will flash. This feature can be turned on or off via the configuration program.
There are several types of UWB data packets sent by location tags. The most basic UWB data packet only contains location data, has the shortest length, takes the shortest time in the air, and saves the most power.
