Hi @jkandasa and thanks a lot for your answer!
Here is my gateway sketch:
// Enable debug prints to serial monitor
#define MY_DEBUG
// Enable and select radio type attached
#define MY_RADIO_RFM69
#define MY_IS_RFM69HW
#define MY_RFM69_FREQUENCY (RFM69_868MHZ)
// Enable serial gateway
#define MY_GATEWAY_SERIAL
#include <MySensors.h>
void setup()
{
// Setup locally attached sensors
}
void presentation()
{
// Present locally attached sensors
}
void loop()
{
// Send locally attached sensor data here
}
I enabled MY_DEBUG but it may be a mistake and the cause of the problem. I'll try without!
I got it for the button part, everything looks ok for my dummy node, thanks!
