Hi,
I have additional information regarding the problem with the communication from pc to node.
If I use transparent base on two nodes and I am sending a message over uart to node a with the address of nodeb it works.
But if I want to send a message over uart to nodea, how can I do that?
I tried the node id as addres of node a and 0x007E, but nothing is working. For radio I calculate the crc and it works fine. Should I remove the crc if the message is addressed to the node of uart?
Only every second message is received by nodea. If I use two nodes, everything is working fine.
Best Regards,
Patrick

Hi,I have used mica2 nodes. Now I try to communicate with telosb nodes. On pc I use a serialport. Reception of the messages works fine, but when I want to send messages I observe problems:I send a message like this:length = 3;fcfhi = 08;fcfh0 = 0;dsn = 1D;destpan = 0403;addr = 1111; (Address of node)type = 63;group = 7D (standard)data = 3 bytesThen I escape this bytes and put 7E42 before the message and 7E after the message. Then I send the message.On the node I indicate the reception with leds.toggle...Depending on the length the light changes with every two messages or always.I do not need to put a CRC into the message? I tried that too and get the same results. Is there a general thing I do wrong?On mica2 this worked fine. However the structure of the message is different.Best Regards,Patrick
