Hi All, We recently observed an unexpected behavior of the CC2420 radio on MICAZ. I wonder if you had similar experience and any insights to this problem.
We scheduled a timer to turn on CC2420 at a specified time. The radio, however, was turned on more than 200ms later than the specified time. In the system, the only other workload we had is some writing to the flash using LogStorageC periodically. This strange behavior happens rarely and randomly (about 5 times in 500 attempts to turn on the radio). My question is that if a writing operation to the flash could delay a timer or a radio to be turned on? Through logged trace, we found the timer expired at expected time, it sometimes took the radio about 200ms to be fully turned on. Thank you for your time, Jun _______________________________________________ Tinyos-help mailing list [email protected] https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
