Action Items
Tengfei Chang complete the frequency sweep test from OpenMote to SCuM on other channels
Tengfei Chang design frequency scan algorithms
Minutes
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?)
Update on the programmer
Measure the power of consumption of each led
Tested optical receiver with another Teensy logging DATA, (from one Teensy to another?) Teensy (the one used for logging?) reads wrong values
Kristofer PISTER Just use the logic analyzer instead 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
ADC rate-spot testing
update on SCuM and zappyv2
show the result of VDDSCuM I vs V under 2 suns
video shows SCuM is working with solar powered
