Hello!
I am trying to send some messages to the serial port in order to process
them with a java application. But something goes wrong, the java app does
not "see" the packets arriving to the serial port. So either I do not send
them to the serial port correctly or the java app is not correct. Or both.
I am using a telosb mote connected to usb port which receives a message
every second. The mote sends another message over the radio and forwards
the received message (after some changes) to the serial port. In order to
send to the serial port I have written:
module MineC{
...
uses interface AMSend as UartAMSend;
uses interface Packet as UartPacket;
...
}
implementation{
...
message_t packet_uart;
...
event message_t* RadioReceive.receive(message_t* msg, void* payload,
uint8_t len){
...
MineMsg* pkt3=(MineMsg*)(call
UartPacket.getPayload(&packet_uart,sizeof(MineMsg)));
pkt3->id=u;
pkt3->d=x;
pkt3->c=y;
pkt3->c2=z;
pkt3->t=w;
call UartAMSend.send(TOS_UART_ADDR,&packet_uart,sizeof(MineMsg));
...
}
event void UartAMSend.sendDone(message_t* msg, error_t err){
if(err==SUCCESS){
printf("\n!!!MESSAGE SENT TO SERIAL PORT!!!\n");
}else call
UartAMSend.send(TOS_UART_ADDR,&packet_uart,sizeof(CondMsg));
}
} //end of implementation
and at Mine.h I define TOS_UART_ADDR=0x007E. Also at MineAppC.nc I wire the
interfaces with the components. I compile and install the program and I
don't get any errors. If I run MsgReader tool I get:
serial@/dev/ttyUSB4:115200: resynchronising
serial@/dev/ttyUSB4:115200: bad packet
and then nothing. It does not exit either. If I run Listen tool I a packet
per sec as expected. But the first second I get:
serial@/dev/ttyUSB4:115200: resynchronising

and then every second I get these 7 lines:

That does not seem correct, since the MineMsg is small:
typedef nx_struct mine_msg{
nx_int16_t id;
nx_int16_t d;
nx_int16_t c;
nx_int16_t c2;
nx_int16_t t;
} MineMsg;
and also it's payload should be different every second. Any ideas what do I
do wrong? I am on tinyos -2.1.0.
Thank you all in advance!
