Hello!!
I have started to use RFM69hw with arduino uno board. I have made small board for RFM69hw and i am able to read register values of RFM69hw using arduino uno board (that means connections between uno and RFM69hw is correct). But gateway.ino and node.ino is not working.
Is there any addtional stuff needed to use RFM69hw with Arduino uno board if i dont use Moteino?
Please help..
We will need a lot more detail than "it does not work". But please start by checking around the forum, there have been a few folks who tried the same thing with good results.
After i try to call RGM69.send() function, it draws lots of power and becomes power down in chip.. what should be the reason?

5v perhaps ?
Isn't the RFM69 a 3v3 device ?

This had been discussed in a previous thread. Arduino Uno can only supply 50mA current on its 3.3V power rail. The RFM69HW uses typical 130mA on transmit. If you are powering the RFM69HW from the 3.3V power rail of the Uno, then you are asking for trouble.

Good observation!
