Forgot to mention in the above that I use MRAA to configure the IO pins. Example:
From my Commander test program:
char szDevice[] = "/dev/ttyXBEE";
Commander command = Commander();
...
int main()
{
printf("Arbotox Commander XBee Test!\n"); // Install signal handler to allow us to do some cleanup... struct sigaction sigIntHandler; sigIntHandler.sa_handler = SignalHandler; sigemptyset(&sigIntHandler.sa_mask); sigIntHandler.sa_flags = 0; sigaction(SIGINT, &sigIntHandler, NULL); mraa_uart_context uart; mraa_init(); uart = mraa_uart_init(0); if (uart == NULL) { printf("MRAA UART failed to setup\n"); } // Lets try to open the XBee device... command.begin(szDevice, B38400);
So on the Edison on an Arduino board this should setup digital pins 0 and 1 to work as a UART
On the Mini breakout board it should setup MRAA pins 26(J18-13) and 35(J19-8).
I know that I have tried the commander stuff out on Arduino board and I believe I did some testing on mini board, will be trying it again soon, as soon as I solder in the connectors to the new board.
