[Solved] Arduino Nanos don't work as nodes

alowhum

I created a new gateway on an Arduino Nano today, and that worked. Not sure if that was using the very latest MySensors though. The rest of my network is all based on the RF-Nano, which I'm a big fan of. It shields me from exactly these types of issues :-)

How are you powering them?

Tried an external 3.3V regulator

The Nano itself runs on 5v, but I suspect you know that.

Have you tried enabling the advanced radio debug option? (I forget it's name). That can magicaly enable things sometimes. At the very least it will tell you more about what's going on.

Are you sure there's nothing like encrpytion on the gateway?

Built three new boards to plug the radio and the Nano into -

Have you tried replacing all the wires between the nano and the radio module?

I recommend just buying the Arduino Nano Wireless Expansion Board. They cost a dollar on Aliexpress.

Maybe you have some of those fake Atmel chips?

pinMode(A7, INPUT); should not be in presentation. It should be in setup. Similarly, don't put Serial.begin(115200); in there. All that should be in presentation function is sendSketchInfo and present.

Also, don't use "delay", use wait() instead.

And where is your setup function in the first place?

alowhum

Also, your code never loads MySensors? It's commented out?

Your node code is very strange.

How are you powering them?

USB, tried a wall-wart and two different PCs.

Are you sure there's nothing like encrpytion on the gateway?

Yes, it's the default gateway sketch, except configured to use the right channel, data rate and nRF24.

Have you tried replacing all the wires between the nano and the radio module?

Yeah, I have multiple boards, some years old and have worked with other nRF24 projects. Plus, any wiring changes actually break it for things such as RF24.

Have you tried enabling the advanced radio debug option? (I forget it's name).

I'll look into that.

Maybe you have some of those fake Atmel chips?

Three of them bought at different times, and the only issues are with MySensor? :P Seems unlikely.

Avamander

Also, your code never loads MySensors? It's commented out?

Um, line 22 #include <MySensors.h>

Your node code is very strange.

It was of the examples, barely modified.

Ah, you're right. Have been programming in other languages lately, where that indicates a comment.

Is there a reason you're swapping your CE and CS pins?

Avamander

@alowhum said in Arduino Nanos don't work as nodes:

Is there a reason you're swapping your CE and CS pins?

Because they're wired that way and it doesn't/shouldn't matter.

What happens if you remove everything but the essentials for your network here?

Look for something like MY_DEBUG_VERBOSE_NRF24 - something along those lines, for that debug option I mentioned.

Still no reply.

I'm not super experienced using mysensors but I do have 3 nodes working and when first settings things up I had some problems with NODE IDs. It looks like you are setting a Static node Id? Is that ID "free" in the gateway? Have you tried powering of all the nodes you have running, wiping the EEPROM of the gateway, powering up the gateway and shortly after powering up the node?

Someone else perhaps knows this better but, if the gateway don't want to include the node, does that generate the FPAR:No reply?

And also, how is the interrupt pin connected?

electrik

I use Arduinos all the time and have problem with them.
I suggest to start with one of the examples.

The RF channel is the same everywhere I guess?
What does the output on the gateway say?

Avamander

@niclas

It looks like you are setting a Static node Id? Is that ID "free" in the gateway?

Yes, there are no other nodes (other than the one with a different static node ID that works)

Have you tried powering of all the nodes you have running,

Yes.

wiping the EEPROM of the gateway, powering up the gateway and shortly after powering up the node?

Yes, I've wiped EEPROMs of all the nodes.

niclas

@Avamander I meant, have you erased the EEPROM of the gateway?

Avamander

@niclas

I meant, have you erased the EEPROM of the gateway?

Yes, that too.

And also, how is the interrupt pin connected?

The radio's IRQ pin is not connected. (The IRQ pin is only required to be connected if the MY_RX_MESSAGE_BUFFER_FEATURE is defined in the sketch.)

niclas

@Avamander Regarding the interrupt pin, at least when using the RFM95 I need to have the pin connected to be able to receive anything. It doesnt poll the module to check for incoming messages. Maybe its different with nRF24.

I haven't tried messing with the MY_RX_MESSAGE_BUFFER_FEATURE so I wouldnt know about that.

Avamander

@niclas

Well, the documentation says I don't have to have it connected.

@electrik

I suggest to start with one of the examples.

The gateway and node both are examples with the minimal required changes.

The RF channel is the same everywhere I guess?

Yes.

What does the output on the gateway say?

Nothing, totally silent. When I plug in the Mega node, then it starts outputting all the sensor and other data.

Anyways, the weird thing here is that I remember this working a few years or so ago on the same boards and stuff, it just doesn't work now and I have 0 clue why. I'm thinking about downgrading MySensors to 1.something

niclas

@Avamander Found the documentation you were referring to and yes. Seems to be true for the RF24 which I haven't used in a long time.

#define MY_RX_MESSAGE_BUFFER_FEATURE

This enables the receiving buffer feature.

This feature is currently not supported for anything but RF24. Require MY_RF24_IRQ_PIN to be set.

Note: Not supported on ESP8266, ESP32, STM32, nRF5 and sketches that use SoftSPI. See below issue for details https://github.com/mysensors/MySensors/issues/1128

Definition at line 2406 of file MyConfig.h.

electrik

I don't think this is a software issue. More likely your NRF24 is failing.
