Hello people,
I think I'm in the right way. Is it true?
Before send data to serial port, I have to protocol the data.
So, I've tried the following snippet of code:
char i, idx = 1;
char packet[4];
memset(packet, idx++, 4); // data
tmsg_t *msg = new_tmsg(packet + 1, 4 - 1); // protocol
spacket_header_dest_set(msg, 0);
spacket_header_src_set(msg, 1);
spacket_header_length_set(msg, 2);
spacket_header_group_set(msg, 0);
spacket_header_type_set(msg, 9);
for (i = 0; i < 4; i++) {
spacket_data_set(msg, i, packet[i]);
}
int ok = write_serial_packet(src, msg, sizeof(msg));
But, the mote doesn't read the data. What is wrong?
Can anyone send me a snippet of code or buffer?
My data is an array of 4 bytes.
the mote works fine using SerialForwarder and my TestSerial application (java).
Thanks all,
Daniel Patrick
