Hi Ray,

Thanks for the detailed information, and thanks for hanging in here with Ned and I as we sort this out. BTW, congratulations on your new grand baby, that's very exciting!

I now understand much better what you are doing. Earlier on you kinda thru me off with the J1587 as an ASCII encoded data stream. Now that I see you're running everything, CANpod configuration and J1578 data stream, over a reliable Telnet connection, the ASCII data stream makes more sense. It certainly works, and we could do it with our SANduino as you describe by using extra processing in an rPi. Alternatively we may be able to implement a full TCP/IP stack with a Telnet server in an Arduino, but we have such limited processing power and memory it's doubtful. I'll have to look around to see what's available. A full TCP/IP stack and Telnet connection is great if you want to transmit long distance, say across the internet, but for a SAN inside a bus I think it's kinda heavy weight. Is there another option with CANpod where you can receive the data stream as a UDP datagram? That would be much lighter. Even for your existing product, a lightweight UDP connection for the data might be preferable in terms of processing power needed. I'm wondering about CANpod sending J1578 over UDP/IP. I understand from the folks at CANpod that they can do this - maybe we misunderstood each other. Nonetheless, you're proposal is a solution. Thank you!
