Title: RFM69HCW Problem
Post by: GjBob on March 14, 2014, 01:37:31 PM
Good Evening,since this is my first post hello to all.

I'm trying to integrate the RFM69HCW in my project but i'im having quite some problems. I configure the sender in packet mode(fixed lenght)using only the synch word generation and no address filtering. I tried to transmit a 2 byte packet and got no output on the spectrum analyzer until i enabled PA1 instead of PA0. At this poin i assume that the module is transmitting ( but i'm not 100% sure). On the other side using the same settings but with the module in rx mode waiting for the "PayloadReady" to become high but nothing happens. Here is my register dump , i really can't understand what i'm doing wrong

I believe the RFM69HCW and HW modules need to have their power specifically set. You miht check to see if that was done.

I'm not sure that's the case. The transceiver chip is the same and hence the firmware usage is the same.
GjBob - not sure how to help since you're not using the LowPowerLab RFM69 library - www.github.com/lowpowerlab/rfm69
