I am using a raspberry pi as the brain of a mobile robot. For debug reasons I'd like to keep a wireless connection with a PC. Communication speed is probably not an issue here, but a little bit of headroom would be great.
Is there an easy-to-use wireless communication way that does (ideally) not need a self-built application running on the debug PC?
- low power usage (the robot is running of a 3000mAh battery, so every mA saved is important)
- low processing usage (there will be some image processing getting on)
- ease of use (on the RPi on one hand, also on the PC - "open a website" is better than "write your own program")
I've looked into bluetooth, but I couldn't find an easy way to implement it on the debug PC. Also I considered the idea of using a wifi-stick with a simple web server running on the pi, but I can't really tell whether this will put a burden on the power and processing time.
