What radio to use? NRF24L01+, RFM69, RFM73 ?

[Cliff Karlsson]

Hmm...

I just connected both gateway and temp sensor to the same computer and used the serial monitor and now it shows temp info

I don´t know if it is a range problem or if it is my controller platform.
I am using a raspberry pi and domoticz and I get a lot of errors like:

I have tried using two different raspberry pi´s and tried both the stable and the beta of domoticz and I get the same errors everytime.
I was thinking there was some error in the gateway-sketch/temp-sketch or that the usb-port of the pi could not provide enough power for the nano+RFM69W.

@Cliff-Karlsson glad it works now.
You should now try to use a different power source for node and see if it's stil working. Next start to move your node.
Regarding domoticz outputs, these are not errors but' just logs from raspberry motherboard sensors.

Well - the good news is that mine is working now. The ??? news is that I'm not sure why. I was using an Uno as my gateway (w/ a dipole antenna) and a 5V mini (small helical antenna) as the sensor and couldn't get anything to go between them. To simply things, I changed the Uno to a 3V mini w/ a monopole antenna and got some traffic, but not very consistent. So I shut everything down, ate some dinner, watched some TV and came back to it. Turned both nodes on and everything was working fine. I rigged up a battery and booster to the 5V mini and started moving it around the house and it's working perfectly. Basically there doesn't seem to be anywhere on my property that I can't get a signal.

The 5V mini is using a level shifter on all the lines (including IRQ) except MISO so I'll try removing the IRQ shifting next to make sure it works without that. And I need to see if I can get the Uno working as the gateway.

My best guess is that I had a loose connection in the breadboard (i.e. maybe I should stop buying cheap breadboards). Or maybe start using wire wrap for my prototypes.

Great!

So does the RFMxx need level shifters? I was under impression they were like that NRF24LO1+ and could just be wired direct to the minis.

@shabba levels shifters needed, unless with pro mini 3.3v

Hi I had my RFM69(H)W Gateway and sensors working after several days of trial and error. A couple of days ago I started fiddeling around with the gateways when trying to add a NRF radio. The nrf works great but now my RFM69 has stopped working.

Can anyone write down a complete step by step instruction of how to get the Serial gateway and sensors working using the RFM69.

This is what I have done:

MyConfig.h - Checked that the right radio options was selected.

Mysensor.h - Added

#include "MyTransportRFM69.h"

//MySensor(MyTransport &radio =*new MyTransportNRF24(), MyHw &hw=*new MyHwDriver()
MySensor(MyTransport &radio =*new MyTransportRFM69(), MyHw &hw=*new MyHwDriver()

SerialGateway:
added:
"MyTransportRFM69 transport (RFM69_FREQUENCY, RFM69_NETWORKID, RF69_SPI_CS, RF69_IRQ_PIN, true, RF69_IRQ_NUM) ;" (I have the H version on the gateway)

Are there any more steps? anything more I need to add to the SerialGateway Sketch?
The Sensor-sketches also seems to have been modified recently, how do I add the Radio info in the sketches?

[shabba]

Did anyone manage to get direct raspberry pi to RFM69 working? About to roll out a rfm69 network beside my nrf24 one.

[mahesh2000]

hi, is there something like the nRF24LE1 (which has an nRF24L01 and 8051 microprocessor in one chip) in the RFM family? thanks!

@mahesh2000 please don't post the same question in multiple places. It wastes people's time when some details are available in one thread and some details in another thread.
To anyone responding to @mahesh2000's question, please reply in https://forum.mysensors.org/post/85838 instead.
