Hello,
I am sending some packets from two micaz motes to base station.The data
observed using xlisten program.Some times i am getting crc value 3
bytes.Actually it should be 2 bytes according to TOS_Msg structure.Can
somebody explain me this.
something like following.I should get all 15 byte pac
Hi Umesh,
that's just the ordinary escaping scheme of the 0x7D sync byte. It's done
by stuffing a 0x7D into the stream and XORing the actual byte with 0x20
(0x7D xor 0x20 = 0x5D). In your case, the crc happens to have 0x7D on that
line. A search on the list will tell you more if you want.
