Iteration 1: What we learned?• Arduino – not a low power MCU• Target battery life: Several months – 1 Year.
• Arduino Firmware is fine, but we need deeper level of control• Task scheduling• Power saving modes
• Need low power standards based protocols• AM consumes too much power• Problems with Scalability, PAN, Healing…
• Need an integrated solution• Signal level mismatches (3.3V, 5V), incompatible communication interfaces…
