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

Well I am not very experienced so even the trivial task of creating a simple sketch would prove a challenge for me :).
But this is the SerialGateway sketch I am using:
#define NO_PORTB_PINCHANGES #include <MySigningNone.h> #include <MyTransportRFM69.h> //#include <MyTransportNRF24.h> #include <MyHwATMega328.h> #include <MySigningAtsha204Soft.h> #include <MySigningAtsha204.h> #include <SPI.h> #include <MyParserSerial.h> #include <MySensor.h> #include <stdarg.h> #include <PinChangeInt.h> #include "GatewayUtil.h" #define INCLUSION_MODE_TIME 1 // Number of minutes inclusion mode is enabled #define INCLUSION_MODE_PIN 3 // Digital pin used for inclusion mode button #define RADIO_ERROR_LED_PIN 4 // Error led pin #define RADIO_RX_LED_PIN 6 // Receive led pin #define RADIO_TX_LED_PIN 5 // the PCB, on board LED // NRFRF24L01 radio driver (set low transmit power by default) //MyTransportNRF24 transport(RF24_CE_PIN, RF24_CS_PIN, RF24_PA_LEVEL_GW); //MyTransportRFM69 transport; MyTransportRFM69 transport(RFM69_FREQUENCY, RFM69_NETWORKID, RF69_SPI_CS, RF69_IRQ_PIN, false, RF69_IRQ_NUM); // Message signing driver (signer needed if MY_SIGNING_FEATURE is turned on in MyConfig.h) //MySigningNone signer; //MySigningAtsha204Soft signer; //MySigningAtsha204 signer; // Hardware profile MyHwATMega328 hw; // Construct MySensors library (signer needed if MY_SIGNING_FEATURE is turned on in MyConfig.h) // To use LEDs blinking, uncomment WITH_LEDS_BLINKING in MyConfig.h #ifdef WITH_LEDS_BLINKING MySensor gw(transport, hw /*, signer*/, RADIO_RX_LED_PIN, RADIO_TX_LED_PIN, RADIO_ERROR_LED_PIN); #else MySensor gw(transport, hw /*, signer*/); #endif char inputString[MAX_RECEIVE_LENGTH] = ""; // A string to hold incoming commands from serial/ethernet interface int inputPos = 0; boolean commandComplete = false; // whether the string is complete void parseAndSend(char *commandBuffer); void output(const char *fmt, ... ) { va_list args; va_start (args, fmt ); vsnprintf_P(serialBuffer, MAX_SEND_LENGTH, fmt, args); va_end (args); Serial.print(serialBuffer); } void setup() { gw.begin(incomingMessage, 0, true, 0); setupGateway(INCLUSION_MODE_PIN, INCLUSION_MODE_TIME, output); // Add interrupt for inclusion button to pin PCintPort::attachInterrupt(pinInclusion, startInclusionInterrupt, RISING); // Send startup log message on serial serial(PSTR("0;0;%d;0;%d;Gateway startup complete.\n"), C_INTERNAL, I_GATEWAY_READY); } void loop() { gw.process(); checkButtonTriggeredInclusion(); checkInclusionFinished(); if (commandComplete) { // A command wass issued from serial interface // We will now try to send it to the actuator parseAndSend(gw, inputString); commandComplete = false; inputPos = 0; } } /* SerialEvent occurs whenever a new data comes in the hardware serial RX. This routine is run between each time loop() runs, so using delay inside loop can delay response. Multiple bytes of data may be available. */ void serialEvent() { while (Serial.available()) { // get the new byte: char inChar = (char)Serial.read(); // if the incoming character is a newline, set a flag // so the main loop can do something about it: if (inputPos<MAX_RECEIVE_LENGTH-1 && !commandComplete) { if (inChar == '\n') { inputString[inputPos] = 0; commandComplete = true; } else { // add it to the inputString: inputString[inputPos] = inChar; inputPos++; } } else { // Incoming message too long. Throw away inputPos = 0; } } }Does it look alright? I am fairly sure that I also tried using
MyTransportRFM69 transport;
instead ofMyTransportRFM69 transport(RFM69_FREQUENCY, RFM69_NETWORKID, RF69_SPI_CS, RF69_IRQ_PIN, false, RF69_IRQ_NUM);
In the serial monitor only this shows:0;0;3;0;9;gateway started, id=0, parent=0, distance=0
0;0;3;0;14;Gateway startup complete.@Cliff-Karlsson First time I used RFM69 I didn't adapt level and the RFM69 initialization couldn't complete : meaning I didn't have the message "Gateway startup complete"
As soon as I used I used resistors to adapt levels, the initialization was fully completed.
So I think that your connections are good.
I think (from memory) that I created MyTransporRFM69 almost the same way as your (I use RFM69HW) :
MyTransportRFM69 transport(RFM69_FREQUENCY, RFM69_NETWORKID, RF69_SPI_CS, RF69_IRQ_PIN, true, RF69_IRQ_NUM);What about your node sketch ? Do you do the same ?
-
I would wonder whether running some signals through the level shifter and some not might cause the signals to arrive out of phase? Anyway, something to consider if you can't get it to work.

Ok, this is my temp sensor sketch. Does it also look Ok?

Well I'm having problems too... :anguished: I'm running basically the same serial gateway code you are and, like you, it starts up fine. For my sensor, I'm using the MockSensor sketch modified to send a counter. That starts up fine as well but can't communicate with the gateway. I tried level shifting IRQ and not level shifting IRQ - no change. Basically the gateway never gets the transmitted message. I'm using a small helical antenna that came w/ the radio on the sensor and a home made dipole on the gateway. I'm going to try and replace my home made antenna with a helical model on the gateway and see what happens.
Here's what I see on the sensor:
find parent send: 254-254-255-255 s=255,c=3,t=7,pt=0,l=0,sg=0,st=bc:I'm using this level shifter. If my antenna mod doesn't work (I'm not expecting it to), I'll try changing this to a resistor network to do the shifting and see if that helps.

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

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.

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.

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? -
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.
