Newbie Problem! Get Started with NRF24L01+

[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);

[fakeJake]

@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: 0-0-255-0 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.

Can I use the inclusion button on the serialGateway?

[korttoma]

@fakeJake said:

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).

[hek]

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.
0;0;3;0;9;read: 1-1-0 s=0,c=1,t=0,pt=7,l=5:30.2
1;0;1;0;0;30.2
0;0;3;0;9;Inclusion started by button.
0;0;3;0;5;1
0;0;3;0;5;0

This is the temp output:

sensor started, id 1
send: 1-1-0-0 s=255,c=0,t=17,pt=0,l=5,st=fail:1.4.1
send: 1-1-0-0 s=255,c=3,t=6,pt=1,l=1,st=ok:0
send: 1-1-0-0 s=255,c=3,t=11,pt=0,l=18,st=fail:Temperature Sensor
send: 1-1-0-0 s=255,c=3,t=12,pt=0,l=3,st=fail:1.0
send: 1-1-0-0 s=0,c=0,t=6,pt=0,l=5,st=fail:1.4.1
send: 1-1-0-0 s=0,c=1,t=0,pt=7,l=5,st=fail:30.2

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:

[rvendrame]

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...
