From 4

th
is the MAC address of the module, the later 12 is username and password, these are 6 bits add 0 if
less than 6, the last one is parity.

Net return the command
①
The result of search command return
The result of search command return( 36 bits): FF 24 01 00 00 c0 a8 00 07 00 71 77 7c 42 2F 01 0c 00 00 55 53 52
2d 4b 32 00 00 00 00 00 00 00 00 00 00 F2,
Parity way is reduce parity sum, the initial value is 0x00, reduce every bits in order, algorithm is as fellow: F2 = 00 -
FF - 24 - 01 - 00 - 4B - ... - 32 – 00-…-00.

Check sum initial value is 0x00, reduce every bits of
TAG_STATUS in order,till the last bit, and the result is
