Hi, Brandon,
I have the same question. I download the code in file "Sensor_Demo_AP_as_Data_Hub.eww" which is included in "slac139f.zip" to both of the ED and AP. Then no information from ED is shown on the temperature monitor, and the temperature from AP updates occasionally without a constant frequency, and its LEDs are blinking with different frequencies. In addition, the AP temperature will not update until ED is powered on.
Do you have any idea about this problem?
