[Tinyos-help] sendDone not signalled when i send packet over radio

[Bhavish Aggarwal]

I am writing an application to bridge packets from UART to radio in
tinyos 1. The send command on the radio returns a success but the
senddone event is not signalled. Could anyone please help me with this
issue. The code is as below.

Thanks,

Bhavish

module UARTToRadioM{
        provides{
                interface StdControl;
        }
        uses{
                interface StdControl as UARTControl;
                interface ReceiveMsg as UARTReceive;
            interface BareSendMsg as UARTSend;
            interface TokenReceiveMsg as UARTTokenReceive;

                interface StdControl as RadioControl;
                interface BareSendMsg as RadioSend;
                interface ReceiveMsg as RadioReceive;

                interface Leds;
        }
}
