3.3.2 How to Send Commands Using Network Connections

Data the host sends to the device via the network connection must follow the SLIP protocol as defined in
Part D, Section 3 of Specification of the Bluetooth System, Host Controller Interface, Volume 4,
which is available at https://www.bluetooth.org/Technical/Specifications/adopted.htm. Note the reference
to bluetooth.org is intentional, and the specification does indeed apply to the device's network
connection.
The host software should begin and end commands with SLIP's frame delimiter C0, and must take into
account SLIP escape sequences that deal with occurrences of C0 inside the SLIP data frame:

If outbound data contains the byte value C0, software should encode it into SLIP as DB DC; if
inbound SLIP data contains the byte sequence DB DC, software should decode it to C0.

If outbound data contains the byte value DB, software should encode it into SLIP as DB DD; if
inbound SLIP data contains the byte sequence DB DD, software should decode it to DB.
To communicate with a device using the network connection, the host should wrap all commands in the
following block:
Table 3-3 - Network Connection Command Wrapper
Bit 7
Byte 0 0xC0 = SLIP frame delimiter
0x00 = Get
Byte 1
0x01 = Set
Byte 2 .. Command as defined in section 4 Command Set. See SLIP specification for requirements
Byte n about re-encoding occurrences of frame delimiter C0.
Byte n+1 0xC0 = SLIP frame delimiter
The device wraps all responses in the following block:
Table 3-4 - Network Connection Response Wrapper
Bit 7
Byte 0 0xC0 = SLIP frame delimiter
0x02 = Response to a command
Byte 1
0x03 = Unsolicited transmission for an event.
Byte 2 .. Response as defined in section 4 Command Set. See SLIP specification for requirements
Byte n about decoding DB xx byte sequences.
Byte n+1 0xC0 = SLIP frame delimiter
