Notes

  • @Titan Yuan Goal is to integrate self-calibration code into OpenWSN code so the mote can calibrate without impacting higher level stacks

    • Testing is challenging because SCuM crashes after lots of printf statements, sometimes lasts as long as 15 seconds. Usually transmit stops working (timer fails first?)

    • Good topic for workshop discussion

    • MSF (minimum scheduling function) housekeeping function checks every 5 seconds

      • Using printf inside that function may be at fault? consider toggling a GPIO

    • Crashing still happens when printf statements are all removed

    • Acks to set up the network are inconsistently received; guesses include printf issues and WiFi interference

      • Try putting the openmote and SCuM in a readily available metal box and try again to see if reliability improves

  • @David Burnett discussed CRC issues in dehdlcify

  • @Fil Maksimovic explored crashing issues

    • Super simple hello world app runs for many hours

    • Using timers to print hello world crashes in minutes
