Simultaneous transmission to all motes over usb would be difficult over a point to point link such as USB . USB host schedules transmissions to individual endpoints on a 1 ms granularity, and depending on the precise timing of requests you may observe as much as 2 ms between requests. It sounds like if you want motes to receive a message simultaneously, a radio broadcast channel may be appropriate.
Mmmm... Perhaps a better solution would be to use both USB and radio... I have used SerialForwarder Multiplexer but I am not getting very good results and I am thinking that using multiple instances of SerialForwarder and mapping might be more work but in the end the computer-mote communication should be more reliable this way... - J. _______________________________________________ Tinyos-help mailing list [email protected] https://mail.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
