Newbie Problem! Get Started with NRF24L01+
-
@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.
-
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:
0;0;3;0;14;Gateway startup complete. 0;0;3;0;9;read: 2-2-0 s=255,c=0,t=18,pt=0,l=5:1.4.1 2;255;0;0;18;1.4.1 0;0;3;0;9;read: 2-2-0 s=255,c=3,t=6,pt=1,l=1:0 2;255;3;0;6;0 0;0;3;0;9;read: 2-2-0 s=255,c=3,t=11,pt=0,l=5:Relay 2;255;3;0;11;Relay 0;0;3;0;9;read: 2-2-0 s=255,c=3,t=12,pt=0,l=3:1.0 2;255;3;0;12;1.0 0;0;3;0;9;read: 2-2-0 s=1,c=0,t=3,pt=0,l=5:1.4.1 2;1;0;0;3;1.4.1This is the relay output:

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? -
@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
-
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:
0;0;3;0;14;Gateway startup complete. 0;0;3;0;9;read: 2-2-0 s=255,c=0,t=17,pt=0,l=5:1.4.1 2;255;0;0;17;1.4.1 0;0;3;0;9;read: 2-2-0 s=255,c=3,t=6,pt=1,l=1:0 2;255;3;0;6;0 0;0;3;0;9;read: 2-2-0 s=255,c=3,t=11,pt=0,l=5:Relay 2;255;3;0;11;Relay 0;0;3;0;9;read: 2-2-0 s=255,c=3,t=12,pt=0,l=3:1.0 2;255;3;0;12;1.0 0;0;3;0;9;read: 2-2-0 s=1,c=0,t=3,pt=0,l=5:1.4.1 2;1;0;0;3;1.4.1 0;0;3;0;9;send: 0-0-2-2 s=0,c=1,t=2,pt=0,l=1,st=ok:1 0;0;3;0;9;read: 2-2-0 s=0,c=1,t=2,pt=0,l=1:1 2;0;1;1;2;1Relay output after "2;0;1;1;2;1;" :

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.

@rvendrame Sorry I forgot to include that, I edited the post

Can we see your sensor's sketch?
-
I just changed the gw.begin();
// Example sketch showing how to control physical relays. // This example will remember relay state even after power failure. #include <MySensor.h> #include <SPI.h> #define RELAY_1 3 // Arduino Digital I/O pin number for first relay (second on pin+1 etc) #define NUMBER_OF_RELAYS 1 // Total number of attached relays #define RELAY_ON 1 // GPIO value to write to turn on attached relay #define RELAY_OFF 0 // GPIO value to write to turn off attached relay MySensor gw; void setup() { // Initialize library and add callback for incoming messages gw.begin(incomingMessage, 2); // Send the sketch version information to the gateway and Controller gw.sendSketchInfo("Relay", "1.0"); // Fetch relay status for (int sensor=1, pin=RELAY_1; sensor<=NUMBER_OF_RELAYS;sensor++, pin++) { // Register all sensors to gw (they will be created as child devices) gw.present(sensor, S_LIGHT); // Then set relay pins in output mode pinMode(pin, OUTPUT); // Set relay to last known state (using eeprom storage) digitalWrite(pin, gw.loadState(sensor)?RELAY_ON:RELAY_OFF); } } void loop() { // Alway process incoming messages whenever possible gw.process(); } void incomingMessage(const MyMessage &message) { // We only expect one type of message from controller. But we better check anyway. if (message.type==V_LIGHT) { // Change relay state digitalWrite(message.sensor-1+RELAY_1, message.getBool()?RELAY_ON:RELAY_OFF); // Store state in eeprom gw.saveState(message.sensor, message.getBool()); // Write some debug info Serial.print("Incoming change for sensor:"); Serial.print(message.sensor); Serial.print(", New status: "); Serial.println(message.getBool()); } } -
@fakeJake said:
> Incoming change for sensor:0Means your are asking to activate relay 'zero'.
digitalWrite(message.sensor-1+RELAY_1, message.getBool()?RELAY_ON:RELAY_OFF);So digital pin will be 0 - 1 + RELAY_1 = 0 - 1 + 3 = 2
Conclusion: Try activating relay 1 instead 0. ;-)

@rvendrame The light is still not turning on :sweat:
I even change it to "2;257;1;1;2;1" just incase 255 is the message.sensor but it still prints "2;1;1;1;2;1" so I there's no problem there.sensor started, id 2 send: 2-2-0-0 s=255,c=0,t=17,pt=0,l=5,st=ok:1.4.1 send: 2-2-0-0 s=255,c=3,t=6,pt=1,l=1,st=ok:0 send: 2-2-0-0 s=255,c=3,t=11,pt=0,l=5,st=ok:Relay send: 2-2-0-0 s=255,c=3,t=12,pt=0,l=3,st=ok:1.0 send: 2-2-0-0 s=1,c=0,t=3,pt=0,l=5,st=ok:1.4.1 read: 0-0-2 s=1,c=1,t=2,pt=0,l=1:1 send: 2-2-0-0 s=1,c=1,t=2,pt=0,l=1,st=ok:1 Incoming change for sensor:1, New status: 1 -
how the relay is connected to arduino pin 3? Is there a transistor in between?
-
@rvendrame No transistor. I just followed MySensors: Build Relay Actuator. I directly connected the 5v, gnd and signal to the arduino.
-
Do you have a standalone relay, or a arduino relay board, like this picture?
http://www.mysensors.org/relay/relayModule.pngThe board contains a transistor. Some boards also have a 'hi-low' switch, if yours have it, you may try to play with it.
The arduino output is max of 40ma and will eventually burn or not operate correctly if connected directly to a relay. You must have a transistor in between.
Make sure you relay board contains at least this circuit: http://www.electroschematics.com/8975/arduino-control-relay/

@rvendrame My relay is more like this http://www.elecdesignworks.com/images/stories/virtuemart/product/img_62112.jpg
Thank you for your reference.
It has a transistor. I hope it's ok to use. I have tested it by following an instructable. -

@rvendrame You know what. I'm really thankful for you help and I'm really sorry for dragging you with me. I can turn the light on now. I just have to print "2;1;1;1;2;0;" instead of "2;1;1;1;2;1".
I will check if I will encounter any problem because of my relay module.
Again, thank you so much for your help. And I'm really sorry. -
Just swap the 0 & 1 here:
#define RELAY_ON 1 // GPIO value to write to turn on attached relay #define RELAY_OFF 0 // GPIO value to write to turn off attached relayand it will obey as you expect. Some relays boards have inverted input (Zero/GND is ON and VCC is OFF) ;-)
I'm glad it worked.
