Version of the protocol
The following examples show how the connect message is structured and sent:
The messages ID for Connect is 01
hex
, as UINT16, little-endian: 01
hex
00
hex
Then the user data length follows. The Connect message has no user data and so the length is Null. As UINT16
in little-endian: 00
hex
00
hex
There are no user data, the message is now complete.
The entire Connect command is thus:
00
hex
01
hex
00
hex
00
hex
The message is coded in C language:
unsigned char[ ] connect =
{
0x01, 0x00,
0x00, 0x00
};
Therefore:
Message from the client to BVS ID : 01 00 00 00
BVS ID responds to it with: 01 00 04 00 00 00 01 00
