Hi all. I am begginer. Please help me. I clear EEPROM in my Arduino Mini Pro by this manual:

Write this as sketch. After that i write sketch to control 2x Relays in MySensors and sketch upload successfull. But not working... No connect to MySensorns Gateway and Relay not start. I test it also on second device and the same problem. Connection wire is all ok. I check it.
This problem is after clear EEPROM. Please help me .... Please.

Could you please:

• attach your sketch
• enable debug and attach the serial output

I can thin of

• problems with assigning a new node-id (controller)
• problems with encryption keys stored in eeprom

That sketch initialises EEPROm to zeroes which isn't the factory value, 0xff.

Use the MySensors provided sketch instead:
