Hello,
I am modifying RssiDemo to read tx power values in addition to rssi values.
What I did was:
1. added a field in the RssiMsg:
typedef nx_struct RssiMsg{
nx_int16_t rssi;
nx_uint16_t tx_power_reading; //new
} RssiMsg;
2. read the tx power on the SendingMote:
event void SendTimer.fired(){
RssiMsg* buf = (RssiMsg*)(call RssiMsgSend.getPayload(&msg,
sizeof(RssiMsg)));
tx_power = call PacketTransmitPower.get(&msg); /*new*/
buf->tx_power_reading = tx_power; /*new*/
call RssiMsgSend.send(AM_BROADCAST_ADDR, &msg, sizeof(RssiMsg));
}
3. In java code (after make), print out the tx power:
public void messageReceived(int to, Message message) {
RssiMsg msg = (RssiMsg) message;
int source = message.getSerialPacket().get_header_src();
System.out.println("Rssi Message received from node " + source +
": Rssi = " + msg.get_rssi() +
": Tx power = " + msg.get_tx_power_reading()); /*new*/
}
So everything was compiled and installed ok. But the tx power output is
always 0 even it's actually should be 0xF as defined by
tos/platform/iris/chips/rf230/HplRF230.h.
Any idea?
David
