follow

command packet.
Byte 3: The Application Layer Data Count(DC); for this packet it is 1 data byte to follow.
Byte 4: The Application Command Data: This IR Command Packet is transmitting Key Code
“Volume Up”(17 hex). To transmit other IR Key Codes the user would replace this byte
with other IR key codes as found in
