Hi，Patrick. I hope you think it's ok that I list your test here. Thank you for your attention and reply.
TFmini outputs the ASCLL code value in pix mode in meter units not in decimeters. And this is caused by different TFmini version you got.
TFmini is divided into cm value output and mm value output, the two output modes can be converted to each other, but the resolution is cm level. When pix mode, the unit is m, and resolution is cm. So it's better to input the command in cm level unit.
For short distance error issue, new version TFmini has better performance.
