Hi,
I was finally able to solve the "MsgReader" issue as I was trying to build a
"TestNetworkMsg.java" and try to see just that structure. Earlier I could just
use the Listen tool and correctly see the Serial Frame. The problem was that my
"SerialAMSenderC" had [CL_TEST] as the Active message type... whereas it should
have been AM_TESTNETWORKMSG as "SerialAMSenderC[AM_TESTNETWORKMSG]", so once I
changed to this, I started receiving the messages as:
$ java net.tinyos.tools.MsgReader TestNetworkMsg
[EMAIL PROTECTED]:57600: resynchronising
1216087012968: Message <TestNetworkMsg>
[source=0x1]
[seqno=0x15]
[parent=0x3]
[metric=0x1ee]
[eventdata=0x3]
[hopcount=0x0]
[sendCount=0x101]
[sendSuccessCount=0xf400]
BUT NOW the problem is that the data I am getting is firstly the ctp_header:
typedef nx_struct {
nx_ctp_options_t options;
nx_uint8_t thl;
nx_uint16_t etx;
nx_am_addr_t origin;
nx_uint8_t originSeqNo;
nx_collection_id_t type;
nx_uint8_t data[0];
} ctp_data_header_t;
As the SerialPacket is
typedef nx_struct serial_packet {
serial_header_t header;
nx_uint8_t data[];
} serial_packet_t;
And the data[] part in the "TestNetwork application" consists of the
ctp_header and then the TestNetworkMsg
Using the Listen tool, I get and output as:
00 FF FF F4 01 17 00 05 00 01 00 19 00 06 04 EE 00 06 00 04 01 F4 00 19 00 06
00 00 00 00 00
00 FF FF F4 01 17 00 05 - Serial Header
00 01 00 19 00 06 04 EE - Ctp Header
00 06 00 04 01 F4 00 19 00 06 00 00 00 00 00 - TestNetworkMsg
My makefile looks like this:
BUILD_EXTRA_DEPS += TestNetwork.class
CLEAN_EXTRA = *.class TestNetworkMsg.java
TestNetwork.class: $(wildcard *.java) TestNetworkMsg.java
javac *.java
TestNetworkMsg.java:
mig java -target=null -java-classname=TestNetworkMsg
../TestNetwork.h TestNetworkMsg -o $@
I know that I somehow need to tell here that it needs to take the ctp_header as
well into consideration while building the TestNetworkMsg.java file. Can
anyone suggest how can I do that?
If I go and change the automatically mig generated TestNetworkMsg.java file,
then I get the correct data but I have to modify the TestNetwork file as marked
in RED:
// Message-type-specific access methods appear below.

return (64 / 8);
}

public static int offsetBits_source() {
return 64;
}

public int get_source() {
return (int)getUIntBEElement(offsetBits_source(), 16);
}
/**

public void set_source(int value) {
setUIntBEElement(offsetBits_source(), 16, value);
}
/**

public static int size_source() {
return (16 / 8);
}
/**
* Return the size, in bits, of the field 'source'
*/
public static int sizeBits_source() {
return 16;
}
I hope I was able to explain the issue......
