Title: Arduino Yun mini and RFM69HCW
Post by: sgoudelis on September 11, 2016, 05:40:33 PM
Hello,

I am trying to setup a Yun mini to use an Adafruit RFM69HCW breakout circuit. I am having issues making this work. I believe I have connected everything correctly since for the first few seconds after boot of the MCU of the Yun, I receive and I can send messages to other systems and see the ACKs. After a few seconds though this stops and I cannot receive anything or receive acks that my messages were send. I after reading a a bit I am starting to suspect that the shared hardware IRQ pins on the Yun are the issue. Has any one ever used this combination of Yun/RFM69 ? Has anyone had the same issues as me ? Is there a way to fix this ?

I am using this library: https://github.com/LowPowerLab/RFM69

Regards

Is the FTDI adapter able to source enough current to run the RFM69HCW?  I know when I pair a 3.3V pro mini with my RFM69HCW breakout board my FTDI cannot handle it and it able to get a packet but dies when it tries to ACK.
