Embedded access point success


After a long fight, the Android finally accepted a connection to the embedded access point. The key is the access point needs to constantly send beacons or the tablet gives up & looks for another router. This scheme is how the tablet pulls off seamless roaming.

Broadcasting beacons is hard, since the embedded USB isn't full duplex. Currently, it relies on other beacons & packets from the tablet to trigger beacon sends.

The big question is now how to run the autopilot on the tablet. Should everything be rewritten in Java with just the image processing left in C? Should a simple GUI abstraction be in Java, with everything left in C?

When the autopilot began in 2007, there were no tablets & no-one knew what tablets would run. Now we have 3 incompatible frameworks. For all the pedantic correctness of Java, the horrible Android responsiveness make it the disaster in this nest of incompatibility. Having the initialization & main loop behind the JNI presents a fiendish problem.

How will the network & USB be accessed from the native layer?
