| * Simple demo application that sends out hello messages and listens for hello messages. | ||
| * You can run it either on 2 different systems (air unit and ground unit) | ||
| * or run it on the same system with 2 different wifi cards for testing. | ||
| * | ||
| * On success, you should see the air unit talking to the ground unit and vice versa. | ||
| * | ||
| * NOTE: Card(s) need to be in monitor mode & on match on the selected frequency ! | ||
| * NOTE: This example is as simple as possible, and therefore doesn't even need to use the WBStreamTX / WBStreamRX pair | ||
