[Tinyos-help] failure of signal

[Ng Teng Jie]

hi all,
   Does anyone knows what is the cause of the failure of a signal? Specifically in my context:

 m_p_rx_buf = signal Receive.receive( m_p_rx_buf, m_p_rx_buf->data,
                                         rxFrameLength );

Receive.receive interface:
event message_t* receive(message_t* msg, void* payload, uint8_t len);

   in CC2420ReceiveP.nc is executed but my Receive.receive event does not happen. Might it be due to the contents of the argument m_p_rx_buf or data being null or error?


  Thanks for any help rendered! :)

Regards,
tj
