Hello Support，
我的英语很差。如有错误，请见谅。
我正在做DA14583基本套件。我用手机连接三个传感器，使用的是Evothing views和Evothing studio。我有九个传感器。除了修改手机运行的代码连接更多的传感器外，我对keil没有做任何修改。
一开始我使用的是SFL固件，后来由于某些原因，我更改为RAW固件(SDK: DA1458x_IOT_v5.160.1.19)。然后我发现有些传感器连续闪烁了几次，但磁强计的数据是正确的。 Later, I found that this is not a good idea to use the firmware, so I burn back to the SFL firmware. At first, I only focused on accelerometer data, but recently I suddenly found that the magnetometer data was abnormal: for example, some of the sensor data remained the same(as you can see in the PDF) ).The data is like 18,18,0;18,18,0;18,18,0…….. After I burn the firmware it will not immediately change it, but the original firmware . I have tried some methods to receive the correct accelerometer data , such as re-burning the firmware and changing to sample program, but it did not work.
When I conduct experiment, I removed the sensor case directly and attached it to my finger by using a wire that passed through two small holes (senven totally) in the sensor. My goal now is to get the correct magnetometer data, can you help me? The detailed pictures and data are in the PDF.

Best wishes
