[Tinyos-help] question on simple_transmit from Rfm_model.c

[Liu Haibin]

Hi,

I have a question about the following code from Rfm_model.c. The parameter
bit can be 1 or 0. When simple_trasmit is transmitting bit 1,
transmitting[modeID] is set to 1, meaning it's transmitting. However, when
simple_transmit is transmitting bit 0, transmitting[modeID] is set to 0,
meaning it's not transmitting (actually it's transmitting bit 0). Why is it
so? I must have the concept wrong. Could any help me on this?

void simple_transmit(int moteID, char bit) {
  int i;

  transmitting[moteID] = bit;
  for (i = 0; i < tos_state.num_nodes; i++) {
    radio_active[i] += bit;
  }
}


Regards,
Haibin
