  • Jackson Paddock

    • trying to setup simulation

  • Austin Patel

    • still working on the paper

    • presenting results at 35-40 C communicating

    • was hoping to piece the different calibration method together, including 2M

    • Kristofer PISTER solar voltage and current is changing with temperature as well, conceivable that that impacts

    • Kristofer PISTER data at other temperature range? No, just 35-40 C.

    • Kristofer PISTER probably room temperature data is also important.

    • Kristofer PISTER interesting to see why you have such as small range; big difference is running from solar.

    • Austin Patel : smaller 5C range appeared when using solar

    • Kristofer PISTER 260uA at 1 sun, sleep current is 150 uA. would be good to get at 1 sun.

    • Austin Patel : cannot transmit that often, 1.6mA when transmitting, 100 uF cap across VBAT

    • Kristofer PISTER : 280uA 150uA sleeping, 130uA charges cap, filling up cap in <100ms, so you should be able to transmitting 10 packets per second. This calculation should be in the paper.

    • Austin Patel : created Theses & Papers and Project Code

  • Tengfei Chang

    • Overview:

      • Figures almost done, preparing paper for SenSys.

      • Firmware update merged

      • EDHOC update (LAKE WG)

    • Unexplained gaps in the histogram

    • Kristofer PISTER looks like gaps have a certain structure

    • Thomas Watteyne Not a bin artifact when calculating the histograms (aliasing?)

      • try with another number of bins?

    • Kristofer PISTER Run through certification test to show it is standards compliant (100% @ +/- 40 pm)

    • Kristofer PISTER frequency offset measured on OpenMote of 13/14 corresponds to 40 ppm

    • Figures showing LC frequency over changing temperatures

      • 10 packets per second, heat up, record offset and temperature (and group by temperature)

        • whiskers (min/max ?), no outliers

  • Timothy Claeys

    • goes through changes in OpenWSN

      • done: some bug fixes, big change: stack config now merged into main dev branch

      • todo: some further bugs, with larger networks

    • next:

      • working on ECC SW implementation

      • checks in the CI environment, using Flake8 and uncrustify

  • Thomas Watteyne

    • poipoi
