Wireless Communication Options

  • Arduino's official wifi shield is discontinued
  • Could use xbee radio w/ shield
  • Arduino MKR WAN 1300 link
    • new board for arduino, comes out in november

Latency

some digi cards have reported latency issues. might need to change xbee card.

  • might try using GPIO pins on xbee radio to avoid using serial communication
    • need to use 330 ohm resistor + 3.3V zener diode to drop from 5V to 3.3V for each pin
