Reading Settings

The app reads the current IPI FLY PRO configuration by querying several 10-byte memory blocks and decoding known offsets.

Decoded Offsets

Each block response stores its 10 data bytes in response bytes 5..14.

Block 0x00

Config address	Response byte	Meaning
0x00	b00[5]	Polling rate raw value
0x04	b00[9]	Active DPI stage index, 0..3; matches the web-driver dpiGear concept

Polling rate mapping:

Raw	Rate
0x08	125 Hz
0x04	250 Hz
0x02	500 Hz
0x01	1000 Hz
0x10	2000 Hz
0x20	4000 Hz
0x40	8000 Hz

Block 0x0A

Config address	Response byte	Meaning
0x0A	b0a[5]	Lift-off distance raw value
0x0C	b0a[7]	DPI stage 1 raw value
0x10	b0a[11]	DPI stage 2 raw value

LOD mapping:

Raw	LOD
0x03	0.7 mm
0x01	1 mm
0x02	2 mm

DPI values are decoded as:

dpi = (raw + 1) * 50

Block 0x14

Config address	Response byte	Meaning
0x14	b14[5]	DPI stage 3 raw value
0x18	b14[9]	DPI stage 4 raw value

Block 0xAA

Config address	Response byte	Meaning
0xAB	baa[6]	Motion Sync
0xAD	baa[8]	Sleep timer
0xAF	baa[10]	Linear correction
0xB1	baa[12]	Waveform control

Block 0xB4

Config address	Response byte	Meaning
0xB5	bb4[6]	Full-power / rage mode toggle
0xB7	bb4[8]	Rage-time duration in seconds
0xB9	bb4[10]	Work mode; 0 low power, 1 high performance
