Newbie Problem! Get Started with NRF24L01+

[fakeJake]

Good day!

I have a problem setting up my army.
I am planning to monitor my house using a lot of NRF24 modules but instead of connecting to a cloud I want the master NRF to send me a message.

I am very new to this and any help will be truly appreciated.

I have 2x NRF24L01+ Modules and 2x Arduino UNO.
I already have an Arduino IDE so I just downloaded the library.
I uploaded SerialGateway.ino to one of the Arduino and DallasTemperatureSensor.ino to the other.
I followed the wire connection.
I placed capacitor between the 3.3V and GND
I placed inclusion button, leds and resistors.

When I open the Serial Monitor for the SerialGateway, Nothing happens :'(

The led for the inclusion button is not blinking on the SerialGateway
I can't see temp readings on the DallasTemperatureSensor even though I use Serial.print()

am I missing anything?
Do I need to have a controller?
Is Serial.print() not applicable if I am using NRF24?

Just to check, did you upload the DallasTemperatureSensor.ino, or did you upload the Temperature sketch inside the MySensors subfolder?

I'm at work currently so I can't give exact details, but I noticed that if you unpack the MySensors package into the Arduino libraries, you get a heap of example sketches for various items, but then inside the MySensors subfolder are the sketches set up for the MySensors stuff.

So check which one you have used for the remote module with the dallas sensor.

Also on the serial gateway, check the serial output on that (at 115,200 board speed), and check, it should say "Gateway setup complete" or something close to that.

@Chester : Thank you!

I changed baud rate on the Serial Monitor, now it says "0;0;3;0;14;Gateway startup complete."

I used the one inside 'MySensors'. I also changed the baud rate and now it says "check wires"

Why is the inclusion button not working? Will a message show if I press the button?

[Striffster]

Have you set up any controller? For example Domoticz or MYSController?

[fakeJake]

@Striffster : No I haven't. Is it necessary? My plan was to send data using a gsm module after I get it from NRF modules

[Striffster]

I'm kind of a newbie too, but yes I think you need a controller. It's the controller who assigns ID's to the sensor nodes.

[fakeJake]

@Striffster Hmm, so it can't be stand alone? If I press the inclusion button, will it not send the received ID for the NRF module?

[hek]

The serial gateway does not hand out ids by itself.

If you want to create something standalone I suggest you set static id:s on your nodes and don't rely on any configuration (metric/imperial) received from controller.

[fakeJake]

@hek How can I set static IDs?

Second argument to gw.begin(NULL, xxx);

@Chester : After checking the wire and the supply I know my connection isn't the problem so I replaced my Arduino.

This is the output:

send: 255-255-255-255 s=255,c=3,t=7,pt=0,l=0,st=fail:
req node id
send: 255-255-255-0 s=255,c=3,t=3,pt=0,l=0,st=fail:

@hek : After using gw.begin(NULL, 0);

Thi is the output:

send: 0-0-255-255 s=255,c=3,t=7,pt=0,l=0,st=fail:

send: 0-0-255-0 s=255,c=0,t=17,pt=0,l=5,st=fail:1.4.1

send: 0-0-255-0 s=255,c=3,t=11,pt=0,l=18,st=fail:Temperature Sensor
send: 0-0-255-0 s=255,c=3,t=12,pt=0,l=3,st=fail:1.0
send: 0-0-255-0 s=0,c=0,t=6,pt=0,l=5,st=fail:1.4.1
send: 0-0-255-0 s=0,c=1,t=0,pt=7,l=5,st=fail:29.9

What are the s,c,t,pt

[korttoma]

Don't use 0 for your node ID! (gw.begin(NULL, 0);) Choose a value beween 1 and 254.

nodeId - The unique id (1-254) for this sensor.

Do not confuse this with child sensor ID

childSensorId - The unique child id you want to choose for the sensor connected to this Arduino. Range 0-254.

[fakeJake]

@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

[tekka]

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

[fakeJake]

Can I use the inclusion button on the serialGateway?

[korttoma]

@fakeJake said:

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;14;Gateway startup complete.
0;0;3;0;9;Inclusion started by button.
0;0;3;0;5;1
0;0;3;0;5;0

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).
