TCP password authentication
This feature is available only on the module as a TCP server, when the TCP client connection
module, the module will authenticate each connected tcp.
Each TCP client first data is the “p0x0d+0x0a” (the password is Webpage
authentication password). The default password is “admin”, so the first piece of data should be
"0x61 0x64 0x6D 0x69 0x6E 0x0D 0x0A" (Hex). If the password is correct, the module returns
"OK", on the other hand, return to the "NO" and disconnect.

connected to the server with two bytes of ID (ID the range is 0 ~ 65535, the high byte before, and
the low byte behind) plus two bytes ID radix-minus-one complement(or upload 6 bytes MAC
address).Module is the default ID is 1111(MAC:D8B04CF20000), for example, is sent to the
server when the first four bytes "0x57 0x04 0xfb 0xa8"(or "0xD8 0xB0 0x4C 0xF2 0x00 0x00").
There are two ways to upload their own id: one is to upload their own ID/MAC for connection to
