Rflink with RFM69(h)W

[maxtox]

Hello Guys,

OK am just wondering if I can /could use rflink with RFM69?

I think it has better performance and you could use it even with arduino Nano.

Thank you for answer!

No idea if it works better than an Aurel or RXB6..
I have one but did not have time to look at integrating it yet. For now priority goes to CC1101 and CC2500.
The CC2500 is already functioning properly.

The Nano is not important as we are not using that and will not be using it..

Ok... Thank you!

Nano is not my favorite, but the HW version has 20db...so might be good for us

You cannot use RFM69 with RFLink without modifying the sourcecode of RFLink.

Compared to the usual tranceivers, like Aurel tranceiver, the RFM95 is a more complex tranceiver that has several registers that needs to be programmed properly over a SPI-bus before the device can be operated. Parameters that need to be set are: frequency, mode OOK/FSK, bandwidth, datarate and probably some more.

Stuntteam mentioned some time ago that he was busy making RFLink also work with FSK types of modulation but I have not heard news about this for some time.

Okay so I see the following RFM69 modules here... https://github.com/bertrik/rflink:
rfm69.h
rfm69.cpp
rfm69_const.h
RFM69HW are cheaper and have better RX sensitivity in OOK than the Aurel 433 and 868 MHz transceivers, plus they do all frequencies including 315.

I'm new at this and wonder where one would read to figure out how to hook them up and configure OOK at desired frequencies?
Alternately I see CC1100 is supported but it doesn't appear to do universal OOK via SPI since that bypasses software demod, right?

Hi there, this is my first post here.

I have a little experience with MySensors (a few months) and someone on their forum put me onto RFlink.

I love this initiative! Go Stuntteam!!!

But seriously, my issue is this:

I have an Arduino Mega with the firmware (R44) programmed on it.

BUT

I only have RFM69 433Mhz modules in terms of RX/TX at the moment.

Can you please help me with how i would connect my RFM69 up to my Mega so the RFlink firmware recognises it and i can start reading my weather station data and remote switches in Domoticz??

Please anyone can you help??

To get the RFM69 working, I would need to purchase some modules, do tests and make software changes to additionally add that module.
Also note that the RFM is not multi frequency. The chip itself is, but the antenna schematics on these modules are not. So you have to order the module for the right frequency as well.

You could alternatively order a RXB6 from aliexpress or ebay which will cost you around 1 euro and has very good results, possibly even outperforms the RFM.
It also means that I can keep on working on adding new functionality, new freuqencies, new devices etc...

No problem Stuntteam. I'll have to wait for my other stuff to arrive. I'm just impatient to get things going!

Thankyou.
