  • Titan Yuan

    • SCuM BLE TX/RX cal

    • There is bit errors when receiving frame from BLE

    • If flip the bit of input, then there is no interrupt being triggered (which interrupts, the 32rawchip interrupt?)

  • Jove Yuan

    • Update on the programmer

    • Measure Calculated the power of consumption delivered to optical receiver of each ledLED

    • Tested optical receiver with another Teensy logging OPTICAL_DATA , (from one Teensy to another?) from SCuM, Teensy (the one used for logging?) reads wrong values

    • Kristofer PISTER Just use the logic analyzer instead of using Teensy to test

    • Thomas Watteyne Recommended logic analyzer saleae

  • Tengfei Chang and Thomas Watteyne

    • update on frequency sweep experiments

      • OpenMote picks up alternate channel transmissions, explains some earlier results

      • non-linearity of coarse.mid.fine calibratino explains earlier results

      • new results on OpenMote->SCuM calibration

    • all code submitted as PRs, together with tests to run tests on Jenkins at each future PR

    • next week:

      • understand whether we can infer RX settings from TX settings reliably

      • understand whether we can infer “freq+N” settings from “freq“ settings

      • design quickscan algorithm

      • come up with design for cold-boot calibration, options:

        • “Cal box“ with 16x (or less) OpenMotes which ACK

        • “Cal box“ with some OpenMotes which send beacons periodically (fast)

        • just listen to a 6TiSCH network

  • Meera Lester

    • ADC rate-spot testing

  • Alex Moreno

    • update on SCuM and zappyv2

    • show the result of VDDSCuM I vs V under 2 suns

    • video shows SCuM is working with solar powered
