B4J Question Wifi

[Mashiane]

Hi

I want to get a list of available wifi devices, chose one to connect to it, read data from it in specific intervals. Any advice in terms of how I can do this in b4j?

Thanks

Are these devices on the same local network as the computer running the B4J program? If so, check out the jNetwork library, with which you can create Sockets and ServerSockets: https://www.b4x.com/b4j/help/jnetwork.html .

Accessing low-level WiFi stuff (like getting SSIDs) doesn't appear to possible in pure Java; you'll have to use some native access to do that: http://stackoverflow.com/questions/5378103/finding-ssid-of-a-wireless-network-with-java . The last answer at the SO link has a Java program just calling a command line utility in Windows and reading the output to get the SSIDs.
