I’m currently evaluating the distance value given out by the two board. My program is mainly from the example codes of 5a/5b for double sided TWR. I have set the device to use the mode 3.
For evaluation, I have placed both of the device at around 8 meters distance and as you see in my screenshot. The values deviate a lot by having max value of 854 cm and min value of 748 cm. What I observed from the readings is that this pattern keep repeating from the min value to go up slowly and it gives out 96 data before it reaches the max value and back to min.
What are the possibilities that this could occur? Any suggestion are welcome.
