ok guis on my last step of my project i get some really nice problems .....
i have one arduino uno to use serial monitor and one homemade sanguino and the two RFM12B/868S2 Modul:RF;FM;FSK;868MHz;SPI;-105dBm;400kHz mounted on pcb designed by me after the pictures found on internet
and i had modified the schemtic adding a voltage devider to lower 5v to 3.3 and a led with a resistor in praralel and i came up with the attachment ore pictures
the antenna is now quite long but i do not think this is my problem until making this post i tried all libraries but is so hard to debug this ? what problems you had while using your rfm ? what libraries u had used ? you have a litlle sketch for a button on one end and led to the other ? i measured the voltage on my pins and they are reallly low ... but i had used the same resistors in the pictures for debugging where should i start ????? thenx in advance for your advice
