Note
1. When the module is in report mode, it uses this command to send
mouse input information. The first field’s length is 1byte. Bit 0~2
represents mouse press status; bit 3~7 are 0. The second and third
fields are 2 bytes, representing X/Y coordinate drift values. The forth
field’s length is 1 byte, representing mouse wheel value. The X/Y
values are between -2048 to 2047. For instance, “AT+B HIDIRPT
07,\x02\x00\x50\x00\x50\x00\x00\r” represents the mouse position
drift is 0x0050(X) / 0x0050(Y).
Other examples:
Mouse left key pressed down:
AT+B HIDIRPT 07,\X02\X01\X00\X00\X00\X00\X00\r
