From what I understand (reading through the forums and the net), the LCD not being serial, I'll need an arduino for sure on the LCD side, am I right?
Questions: 1) Hooking up a GPS to a wireless makes sense? fast enough for the data? (GPRMC nmea data at 5hz?)
2) On the sensor side, it could be between 2 modems + 0 arduino and 1 modem + 1 arduino.
Along with the LCD display, I would also like to access the wireless data over a computer (pc or android) Questions (cont.): 3) The big one; what kind of wireless protocol is best for what I am trying to do? (Xbee, Wifi, Bluetooth, Radio), I am getting a bit confused on what's available.
Are you familiar with network programming?
Have you a complete list of sensors that will be on the Arduino?
Regarding power consumption - it relates to how busy the wifi chip will be.As a point of example, a rig I have with a WiFly with a 3mA battery 100% uptime and a few sensors ... lasts just under 2 days. With it in a sleep mode for all but 30 seconds out of 5 minutes, the lifetime extends to weeks.
