scale for high acoustic frequency
Altimeter threshold in percents of a full
10
scale for low acoustic frequency
115200 UART baud rate, bps
Near field zone where detection is
500 ignored for high acoustic frequency,
mm
Near field zone where detection is
ignored for low acoustic frequency,
1000 mm. To support D032 model
recommend changing the value to 1500
mm.
