According to the user manual, you can download the corresponding mobile app. I have an iOS phone, so I downloaded the Apple version of NXP rapid lot, and then registered the corresponding account as required to enter the app.
When I first got this kit, I felt it was very novel. However, as I played with it more, I found that it seemed to have some strange problems:
If you connect the app on the initial interface of the kit, after a while, the kit will automatically restart, and then it will be completely disconnected, and no data can be received... Later, I heard from the experts in the WeChat group that it is fine to connect on a non-initial interface. If you return to the initial interface, the kit will automatically restart, and then it will be completely disconnected again. . Resetting the kit doesn't work either..
After I re-downloaded the firmware, the problem was solved. It is estimated that a module in the firmware program is affected by certain values, which will cause this problem.
Analyzing the specific reasons, it may be that there are some small bugs in the program that comes with the kit, causing the BLE connection to return to the initial interface, causing system errors or hitting some instructions, causing the system to restart and lose the previous information after restart.
Later, analyze the source code again to see what the problem is.
However, fortunately, according to the guidance of the great god, as long as you do not return to the initial interface, BLE receives and sends data without any problems.
Here are the related operations:
1. Use data glance to view the temperature data and select sensor data as temperature. 2. Add location and other private information force OTA (force wireless download? Tried and failed...), set address, set location, and personalized image
3. Add personalized image
4. Add data graph, title: TEST, X-ASI: Time-stamp, Y-ASI: sensor temprature.
5. View all information (click on the white, red, blue and other colors below to control the LED on the development kit)
6. Address location, can display longitude and latitude, this is awesome, it should be directly obtained from the Internet
This sharing ends here. Next time, I will share how to get the corresponding data in the cloud.
