[SOLVED] I use serial GW 2.1.1 and my sensor node won't connect

[bjacobse]

I have programmed a Arduino Nano with GW 2.1.1 and my node below is not connecting.
What I find a bit strange is that my "old" 1.5.4 nodes are connecting to the serial gatewayt and appears in Domoticcz - which I somehow then think I am using old version of gateway version?
I am using Ubuntu 16.04LTS, Arduino 1.8.5 and Mysensors 2.1.1 according to the library manager.

My node is an Arduino Pro mini, (as it's a reuse of an old 1.5.4 I have cleared eeprom memory).
Anyone can help getting further?

Below is the serial outpout from my node, it seems that it's not find a gateway?

I can answer myself as I found this very useful link
https://www.mysensors.org/build/parser
No potential parents replied to find parent request, so I assume the gateway isn't adding the node to the network

I just wonder why the gateway isn't accepting and providing a node number to the node?

[scalz]

Hi,
GW doesn't provide id to nodes, so in this case you need to use static id.
in case it still don't work, perhaps try a cleareeprom, or dev branch.

Else it's maybe on hardware side. We ran a few intensive tests with a dozen of nodes yesterday, and it was looking good here but that wasn't the same config (not same mcus, but i had two nrf24 in the equation, plus some others different radios).

If you can't get it working, could you also upload your sketch please?

[bjacobse]

I only used the template for binary sensor, and added voltage measurement.
I thought that the node gets an id from gateway? in the "old" 1.5.4 I didn't do anything special to assign node id. I was sure that nodes automatically gets assigned an node id form gateway?
my sketch below:

@scalz
so it might be my Domoticz controller that won't provide a id to the sensor?
I have tried in Domoticz to "allow new sensors for 5 min" but the sensor wont get an id...

[zboblamont]

@bjacobse I may be completely off the beam here as have not read through it all, and still new at all this, but... Have you enabled "#define MY_INCLUSION_MODE_FEATURE" on the Gateway?
I read somewhere that this is needed for Domoticz after I could not get a Node to similarly connect.

[tbowmo]

@bjacobse

What does the log in domoticz tell you, when you power up gateway / nodes?

"old" nodes (pre 2.1'ish) should be able to communicate with a new gateway (2.1), while the opposite is not true (new nodes running 2.1 is not able to connect to an old 1.5 gateway)

Anyways, check logs on both ends (node, and gateway) to see if there is anything suspicious there..

[bjacobse]

@zboblamont
I used the "original sketch and only updated the #define MY_RF24_PA_LEVEL RF24_PA_MAX

Thank you for the input

I am not sure how I also get debug/serial info out from the gateway meanwhile it's connected to the RPI that is running the Domoticz server, I will check the forum posts, as I haven't thought of this

[zboblamont]

@bjacobse Ok, not experienced enough to offer any further suggestions as still fumbling my own way,...
In my own setup it is standardised on RFM69 radio modules, and the Nework ID is defined at the Gateway and Node, the Node ID is defined at the Node.

[tbowmo]

@bjacobse

As a start, you could shut down the domoticz instance, and connect a terminal program directly to your serial port instead. Then power cycle a few nodes, while recording the output from the gateway.

at the same time, if you could capture the serial output from the power up sequence / first transmission of one of the nodes.

[bjacobse]

@tbowmo
Thank you Thomas for good ideas :-) I will try this when I get time within a few days

Finally I got it, as I have used same hw configuration for ver1.5.4 as for ver 2.1.1 I did not expect any power issues...

a hint for debugging in consol mode linux then use screen
apt-get install screen

then use like this, note that I use udev to always get Domoticz to use correct ttyUSBx, as I have several USB devices attached attached

sudo screen /dev/ttyUSB-mysensor 115200

to kill screen CTRL-a then k and y for confirm

Then I realised that if I use gateway sketch un-modified it is working, and Domoticz is providing node id, (If Domotics is set to allow new sensors, in settings)

So when I change on the PA_LEVEL_HIGH or PA_LEVEL_MAX and use more power consumption, apparently the gateway isn't working. I do have a amplified PA RF24L01 moduleboard.
It's working when set as default PA_LEVEL_LOW

// Set LOW transmit power level as default, if you have an amplified NRF-module and
// power your radio separately with a good regulator you can turn up PA level.

I might have to look into a power USB hub ;-)

Thank you guys for providing input to solve my issue

[mckvack]

I too had problems with my GW resetting.
I use custom designed PCBs with Atmega328p-au using the internal oscillator. With some nodes the GW will reset when I turn them on. Sometimes changing to another NRF-module solved it but this time none of my NRF-modules worked so I searched and found this thread. Flashed the GW with v2.2.0-rc.2 and now all my problems are gone.

[Mario64]

Hi,

I've got across similar problem. What works for you doesn't solve problem in my case.
Decreasing power to PA_LEVEL_LOW or switching to MySensors v2.2.0-rc.2 gives no positive result.

I have some experience with Arduino, but it is my first try with MySensors and Domoticz.

If someone could advice how to cope with, thank you in advance.

Arduino Nano, NRF21+ for GW & Node,
the node is simple actuator: relay with button.

@mario64
Which home automation system are you using?
If using domoticz, then it's vital to accept new sensors, you find it setup->settings
Hardware/Devices:
Accept new Hardware Devices

if this is disabled, no sensors are allowed to be created

Hi @bjacobse,

thank you for answer. I'm back to my project after e few days.
Actually, the "Accept new Hardware Devices" switch is on. I also used the "Alow for 5 minutes" button. Let me share more details:

• pls find log of Domoticz:
