All the details are helpfully on this guy's blog -
Now my motivation for looking into this was the desire to use one of the tablets as a front end for a vehicle diagnostics system.
- Cheap Android tablet computers don't have serial or Bluetooth capabilities;
- Without Bluetooth or serial how do you communicate;
- While these can be added, it is complex as the Android ROM has to be altered;
- They do have wi-fi as standard, but Android doesn't like ad-hoc networks, only access points;
So the RPi acts as a proper AP, not an ad-hoc network, complete with DHCP for managing IP addresses automatically and it can run an Apache server, PHP, MySQL and anything else you fancy.
Now I need to find out more about AJAX.
