@korttoma : Ok. Thank you! Could you kindly explain what are the send, s, c, t, pt, l and st?

rvendrame

Maybe this may cover it http://www.mysensors.org/download/serial_api_14

@fakeJake you could also use the latest release of MYSController (0.1.2.278) to have the debug messages parsed.

Can I use the inclusion button on the serialGateway?

yes

fakeJake

The inclusion button is used to detect the connecting modules, yes?

This is the output I get when I press the inclusion button on the serial gateway

0;0;3;0;9;Inclusion started by button.

I have another NRF module with ds18b20 connected. Can you help me on how I can get the temp sensor to connect to the serial gateway? I c

I used the code here and changed the gw.begin() to gw.begin(NULL, 1)

How are you powering your node? Your node's radio is constantly fail to transmit (st=fail).

How are you powering your node? Your node's radio is constantly fail to transmit (st=fail).

It's actually the gateway having problems transmitting acks back to node.

I'm powering the nrf modules from same 3.3V supply since I haven't bought a regulator yet. I'll test it again later. I'll be going out to buy them now.

Just to give me a heads up. What should the serial gateway get after i press the inclusion button?

fakeJake

Sorry for the late reply

Each modules are now supplied with 5V and 3.3V.

This is the serial gateway output:

0;0;3;0;14;Gateway startup complete.

This is the temp output:

st keeps on failing. I checked the nrf supply and it ranges from 3.1v to 3.3 v. Is this bad? I'm using spx2815 since it's the only thing available to me. I placed 10uF capacitor in the 5v input and 3.3v output to ground

It only explains the "0;0;3;0;14;" but not the "s=255,c=3,t=11,pt=0,l=18,st=fail:Temperature Sensor" that it sends or reads

rvendrame

@fakeJake , are the node far from gateway, or any obstacle (such as a wall) in between? Another source of interference is for example a microwave.

They are just 6 inches apart :worried:

Some people reported trouble with cheap fake radios. If you have spares nRF try replacing one of them or both.

You mentioned a flotation (3.1 to 3.3) in radio VCC, this can also be a reason, as these nRF are very sensible to power variations.

Post your sketches too, just incase...

I'm using the DallasTemperatureSensor.ino on MySensors library. I just change the gw.begin(); to gw.begin(NULL, 1);

// Example sketch showing how to send in OneWire temperature readings
#include <MySensor.h>  
#include <SPI.h>
#include <DallasTemperature.h>
#include <OneWire.h>

#define ONE_WIRE_BUS 3 // Pin where dallase sensor is connected 
#define MAX_ATTACHED_DS18B20 16
unsigned long SLEEP_TIME = 30000; // Sleep time between reads (in milliseconds)
OneWire oneWire(ONE_WIRE_BUS);
DallasTemperature sensors(&oneWire);
MySensor gw;
float lastTemperature[MAX_ATTACHED_DS18B20];
int numSensors=0;
boolean receivedConfig = false;
boolean metric = true; 
// Initialize temperature message
MyMessage msg(0,V_TEMP);

void setup()  
{ 
  // Startup OneWire 
  sensors.begin();

  // Startup and initialize MySensors library. Set callback for incoming messages. 
  gw.begin(NULL,1); 

  // Send the sketch version information to the gateway and Controller
  gw.sendSketchInfo("Temperature Sensor", "1.0");

  // Fetch the number of attached temperature sensors  
  numSensors = sensors.getDeviceCount();

  // Present all sensors to controller
  for (int i=0; i<numSensors && i<MAX_ATTACHED_DS18B20; i++) {   
     gw.present(i, S_TEMP);
  }
}


void loop()     
{     
  // Process incoming messages (like config from server)
  gw.process(); 

  // Fetch temperatures from Dallas sensors
  sensors.requestTemperatures(); 

  // Read temperatures and send them to controller 
  for (int i=0; i<numSensors && i<MAX_ATTACHED_DS18B20; i++) {
 
    // Fetch and round temperature to one decimal
    float temperature = static_cast<float>(static_cast<int>((gw.getConfig().isMetric?sensors.getTempCByIndex(i):sensors.getTempFByIndex(i)) * 10.)) / 10.;
 
    // Only send data if temperature has changed and no error
    if (lastTemperature[i] != temperature && temperature != -127.00) {
 
      // Send in the new temperature
      gw.send(msg.setSensor(i).set(temperature,1));
      lastTemperature[i]=temperature;
    }
  }
  gw.sleep(SLEEP_TIME);
}

Good news! The gateway is now working :)
I changed the dallas temperature to relay actuator and, yes, it's now working!
Bad news is I still don't know what went wrong with my temperature sensor.
I'll investigate on it soon.

This is the gateway output:

This is the relay output:

send: 2-2-0-0 s=1,c=0,t=3,pt=0,l=5,st=ok:1.4.1

I just need to test it.
Since I'll be using a gsm to control the relay. Can you help me on what to send to the relay to turn it on/off?

rvendrame

@fakeJake , I' m glad it worked with relay sketch.

Regarding the temperature, try to move the sensor to other arduino pin. Pin 2 & 3 are used by interrupts and may not play nice with gw.sleep depending on the lib used.

To send a message to the relay , you need a controller connected to the GW, either via USB or ethernet. You can also simulate it by entering the message on the Serial monitor.

The protocol is described here http://www.mysensors.org/download/serial_api_14

fakeJake

I tried entering message on the serial monitor of the gateway but still no luck.
This is the closest thing that I did to tell the relay to turn the light on.

Gateway output after I enter "2;0;1;1;2;1;" to the Serial monitor:

Still it doesn't turn on the light

rvendrame

Maybe you can you connect the node also in a USB port, and open a serial monitor for it? You would see if it is receiving the message correctly.
