[Tinyos-help] message received in TOSBase from OscilloscopeRF

[Nashwa Abo Elneel]

Hi,

I have a question regarding the radio message received by the TOSbase application from the oscilloscopeRF application.

in the TOSBaseM module UARTSendTask, the uartQueueBufs represents the message received from the radio. does the UARTSendTask sends this message to the UART with its originally computed CRC (CRC computed before being transmitted over the radio) ? or it omits this radio CRC and sends the 31 byte length message coming from the oscilloscopeRF application without its original CRC and computes another one based on the UART data format?

in other words, i need to edit the data received from the radio by the TOSBase module before sending it to the UART (for example divide it into two packets and call the sending task twice), does anybody know where exactly can i edit this data before calling the UARTSend.send task? in case i edited this data, shall i recompute the CRC for it again before giving it to the UARTSend.send task or the UARTSend.send task will do the job? 

in case i need to re-compute the CRC shall this be done for the whole TOS_MSG (header and payload)

i hope i made myself clear.

many thanks in advance,
Nashwa
