RFM69W receiver hangs

[eddy6098]

Hi All,
I am basically using two RFM69W modules for trasmitting and receiving data every sec.
It is observed that the transmission takes place every SEC but the receiver node hangs most of the time and the packets are lost in this way (sending data of 40 bytes).
How do I debug this problem? Is there any fix ?

What mcu/hardware?
What library?
What sketch?

Hi Felix,
I am using the hardware from Hope RF (RFM69W) on a RaspberryPi 3 (2 RPi) (for intial tests)
Library from low power labs. Without ACK
Followed the connections from this link (http://rdepablos.merlitec.com/mixed/rfm69-library-for-raspberry-pi)

Thanks,
Eddy

Wait, that's not my library?!

Hi felix,

For connections to the Rpi I reffered to the above link.
But for the library, followed this (https://github.com/LowPowerLab/RFM69 ). This one is right?

[Felix]

My library is for AVRs not for RaspberryPi.

Yes I know this, I have ported your library for Raspberry Pi.
Everthing works fine in the first few minutes and then there are packet losses periodically (roughly 15 secs every time ).
If you have any idea on how to debug this problem would be helpful

Some folks in the forum (I recall joelucid) reported the Pi is noisy and will affect the RFM69.
Otherwise I don't know how to further advise.
