BlueNRG-1 Plus Challenge 2nd Edition @【ST MEMS Sensor Technology Forum】 [Copy link]

 

  After much trouble, I finished the first version and can't wait to publish it. Thanks to Brother Xia for his guidance. //**************************// Update: Sort out the low power consumption mechanism. Add the calculation time mechanism. Not completed: Because the supercapacitor was broken by me, I didn't add the detection of 3.3V and other voltages. Now it is turned on and broadcasted every 10S. The various IOs are not sorted out. Please give me some advice, thank you;

I ran your hex file and the phone did not receive the correct data

The current when idle is more than 1 mA. Is it possible that some low power consumption is not handled properly?

Your app can't be used on my phone, but my dongle can receive it, as shown in the picture

The IO of the 6-axis and the pressure sensor is not handled. I wonder if this is the reason.

I tested your TangDabao_First_Ver_2.hex file and found that the current is still high, 1.31mA when idle. Because the phone cannot receive data, I can see the data with the packet capture software. Now I don't know the corresponding relationship between the broadcast data and the voltage, timing, air pressure, temperature and inclination. Can you tell me more?

Hello, I uploaded it in this way

The data in the red box is the data I received, how can I match it with your format?

Is the voltage always outputting 0V?

I don't know why. My previous test was OK. I will compile it again and send it to you. Please test it again. Thank you

What is the data after your own test? Is each set of data normal and how long can it work?

Hi, here is the data I got.

tang187 posted on 2018-2-7 08:49 Hello, the following is the data I captured.

I tested your file BLE_Examples\BLE_Beacon\MDK-ARM\BlueNRG-1\Release\Objects\BLE_Beacon.bin from February 2. Below are the captured packets and the data received by the phone. The data format seems to be different from your previous version. I used the TangDabao_First_Ver_2.hex test you provided in the post https://bbs.eeworld.com.cn/thread-611993-1-1.html before. The pressure and temperature data are close, but the battery voltage and tilt angle data are incorrect

I saw that your code uses the external pin of ADC to measure the battery voltage. I connected ADC1 to VBLUE and can measure the voltage. The data below is my new measurement. It seems that the counter starts timing when the voltage does not reach 3V. For the inclination angle, it seems that you directly used the X-axis and Y-axis data of the acceleration without calculating the angle.
