Hi,
I´ve bougth several RF69HW chips and i´m having some troubles making them working properly.
At this point ím trying to make somthing like the home automation proyect on instructables but i´m getting stck at the same point avery time.
I have several chips soldered and one of them connected directly to a raspberry.
So then i start with my tests.
My setup si:
one arduino with a lux sensor and a RF69 chip.
On the other side a raspberry with raspbian and a RF69 chip.
When i power up the arduino i can see a message arriving to the raspberry with the right information and format, but then the code get stuck.
Another strange thing is that i cannot get the Serial.println to work after the first radio message, but i know the code goes further because the last thin that i do is to send the information to the raspberry.

This is my first post here so please, let me know what do you need or what missing information is needed to be able to help me track this error.

Sorry for my grammar.
Best regards!

what missing information is needed to be able to help me track this error.

Links to the hardware.
Schematics.
Code on both ends.

Suggest you go look on the Moteino site.

Could you take a look at my code and see what my problems may be? I can't get the rf69hw to talk AT ALL!

Could you take a look at my code

Start at the top of this thread. Locate the reply where you posted the code. Didn't find it? Well, how are we supposed to look at it?

Why haven't you answered ANY of the questions?

Look for libraries and examples at the bottom of this page.

laspenciabrown, I had a ton of problems as well before everything was sorted out.

Check your connections between Arduino and the RFM69 module. My wiring are like this:
RFM69 Arduino UNO Power supply
3.3V VCC
GND GND GND
SCK 13
MISO 12
MOSI 11
NSS 10
DI00 2

I had a bad solder joint that resulted in sporadic data transfer so check your wiring again.
The RFM69 shall have +3.3V as VCC and the logic level is the same. Buy a logic level module for this or connect the RFM69 to a 3.3V Arduino device. DO NOT connect directly to a 5V Arduino! Your RFM69 module may fry!

It's also important to have a powerful power supply for the RFM module. Especially the HW version.
Make sure your not connecting it on Arduino +3,3 out. The RFM69HW shall have an external power supply.

My biggest problem was that I ordered two RFM69HW but got two RFM69W. That resulted in absolutely no communication at all. The reason of that was a call to radio.setHighPower() that is imperative for HW to work but it was the opposite for the W-module. Huge head ache before that was sorted out.

Without libraries and examples from LowPowerLab, I would never have been successful with RFM69 communication. Especially the GarageMote and GarageMote_base examples was a great help. Have a look at this page:

Good luck
