[Tinyos-help] The best way to send messages using SP (Sensornet Protocol)

[Jón Grétar Guðjónsson]

I see it now, you are right, it was a bug in my code causing it to send the
same message over and over again. 

Thanks :)

This is incorrect.  sendDone is only signalled after *all* TOS_Msg
structures in an sp_message_t have been sent.

Have you looked at SP Message Futures?  See:
