Thanks for your reply.
I was using a general serial-port application to send data to the mote, because I want to have my own application to control motes.
My steps:
Firstly, I created a data file with TOS_Msg type; then the application read it and sent data to the base mote through serial port; I programmed the base mote with TOSBase, and tried to check received data in event UARTReveive.receive.
Yes, you are right; the length should be 6. But I'm not sure if the address should be 0x007e, since I'm trying to send data FROM PC TO MOTE through UART. Anyway, even when I changed the two fields, Msg->data is still not correct.
I read SimpleCmdM.nc, which is used when injecting packets (Lesson 7 in Tinyos tutorial). It seems that the received data is also TOS_Msg type (see task void cmdInterpret). I'm really confused.
Thanks a lot.
Best,
Lei

Hi Lei,
Are u trying to send the packet to Micaz using serial Forwarder and
Broadcast Inject. If not, What format are u using to send it???
Note: 10 represents the data length right?? so I think it should be 6 and
not 10. Also, since you are sending the packet to the UART so the
destination address should be the UART address.
My best regards,
Julia
