Ladies and Gentlemen, i seek help with implementation of MAVLink protocol over WIZ750.
The firmware supports packetization character to be configured, but unfortunately it acts as packet “closing” character. The MAVLink protocol uses packet “opening” character of 0xFE.
I need this to be implemented two-way, both at the WIZ750 board and the Virtual Serial Port at the WIndows PC side as well.
Can somebody help me to change the firmware to use this character to act as packet start condition?
when packetization character is received the data collected in the buffer forms a packet and the packet is sent over the Ethernet/UART.
To Be (desired behavior):
when the packetization character is received the data collected in the buffer forms a packet excluding the last received character (the packet marker). This marker character should stay in the buffer to be included in the beginning of next packet.
Thanks in advance for your help or suggestion.
