The last 4 bytes"0x00 0x00 0x33 0x31" are used for checksum out of first two bytes are always 0x00 0x00. This is smallest packets that I have,

00 0b f0 00 00 00 00 01 00 00 00 33 31
In this 33 31 is checksum.

00 0b ff e0 00 00 00 20 ea 00 00 20 c0 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 01 03 07 00 63 52 4f 4d 00 00 00 00 00 00 3d b8
In this checksum is 3d b8. Please help me find checksum algorithm.
