Hello all,

I found that the packets over TCP/IP are normal HDLC packets, without any packing, or change...so sorry for the mails up to here. It would be great if such info is added to the description of SerialForwarder. Because I didn't find any information yesterday, I decided to open socket and see what is received. After few tests and applying correct UART settings, I am having good data stream with HDLC packets.

Hello Shankar

Thank you for the link. But the link that you send me is about the protocol which is used let say between Listener and SerialForwarder. I am looking to replace SerialForwarder with different application. So I need the protocol between the BaseStation mote and the SerialForwarder, when a tcp connection is used. The outgoing protocol after this app is very specific to a GPRS module we use, so I am not sure if it will be of any use to you.

Hello Hristo,

The serial forwarder protocol is here: http://cents.cs.berkeley.edu/tinywiki/index.php/Serial_Forwarder_Protocol

I am also trying to write a java app that can connect to serial forwarder and print the received values to a file. Though I am acquainted with socket programming in Java, I am not able to understand how to use the serial forwarder's protocol. I would be greatful if you can show me your java code.

Thank you.

Regards,
Shankar.

Hello

can anyone give me a link to description of protocol that is used between ethernet connected base station and serial forwarder.
I have such basestation. I connect to it with command:
$ java net.tinyos.sf.SerialForwarder -port 9002 -comm [EMAIL PROTECTED]:9001 &
[1] 532
$ java net.tinyos.tools.Listen -comm [EMAIL PROTECTED]:9002

Now I need to write my own app that will connect to tcp socket, so just link to protocol info is enough for me.
