Ok, I fouind the following defines:

#define APP_TX_DUTYCYCLE                    15000   // Milliseconds between two transmissions
#define APP_TX_DUTYCYCLE_RND                1000    // Random delay for application data transmission duty cycle [ms]
#define APP_DEFAULT_DATARATE                DR_5    // SF7 - BW125
#define APP_PORT                            2       // Application port
#define APP_DATA_SIZE                       16      // Size of packets to transmit in this example
#define APP_DATA_MAX_SIZE                   64      // Size of user data buffer
#define APP_ADR_ON                          1       // Whether we use Adaptive Data Rate or not
#define APP_CONFIRMED_MSG_ON                0       // Whether this example will transmit confirmed or unconfirmed packets

So I guess my second question is answered :slight_smile:

I also found this post - very useful read :+1:
