Hello everyone!
I am currently experiencing a very strange problem. I will put them in context.
I have developed a device to sense the pulses of an energy meter. I use an Arduino ProMini from 5v to 16Mhz and I communicate with a serial Gateway using a pair of radios NRF24L01. Additionally, I designed a board to power my Arduino through the residential AC voltage network.
My problem is the following:
When I connect the device to the FTDI and later to the PC, communication with the Gateway works perfectly. But as soon as I connect the device to the power board for the home electrical network, the device does NOT communicate with the gateway because it causes it to restart. I do not understand why the device, completely isolated to the PC, manages to restart my gateway. When looking at the gateway log, it simply shows that it begins to restart continuously. Can anyone help me? I have checked the Arduino input voltage and it is 5.1V, enough to power it and the radio. Any idea what the problem maybe? Thank you very much in advance for your help. : D

@Anticimex
Okay, so I'll start by tackling things step by step ... How can I avoid getting NACKs in my log?

@Anticimex
Could you please give me the link of the last official release? to verify that is the one that I have. When you say "copy" the keys in the sketch personalizer, are you referring to PERSONALIZE_SOFT? And what do you mean by configuring the sketch personalizer? Could you additionally tell me how it would be done manually? (example of sketch)

@Anticimex And as for the radio. I followed the connection guide that comes out at https://www.mysensors.org/build/serial_gateway, even watching the video. I do not know if you mean another guide? If so, could you give me the link? Thank you for your collaboration.

@Anticimex What I understand is the following:

1. I must choose the backend that I am going to use. (In my case, I'll use the software firm)
2. Then I must choose a free pin to establish a random seed for the pseudorandom generator. (In my case I chose pin A3 that is completely free on the plate).
3. Then I request that all the messages that enter the node will be signed. (I do this using MY_SIGNING_REQUEST_SIGNATURES on the gateway and on the node)
4. finally says that if I am not going to use MY_SIGNING_SIMPLE_PASSWD, I need to customize the node. This is where I get confused ...

First of all, ask me to enable GENERATE_KEYS_SOFT, saying that this will provide random keys for HMAC and AES, and that I should copy and replace them in the corresponding definitions in "User-defined key data". What do you mean by "user-defined key data"? When I enable this, in the LOG of my node nothing strange comes out, the same thing I posted previously.

Second, you tell me to disable the key generator by software and enable the PERSONALIZE_SOFT ... And that this will keep the keys in the EEPROM ... When you talk about enabling and disabling you mean that I must burn the sketch first with Generate_Keys_Soft and then burn again but now with the hmac and aes keys that were generated, while enabling the Personalize_Soft?

This is what I do not understand. I do not get the keys with the GENERATE_KEYS_SOFT ... And I do not clearly understand what I should do next.

You apologize for my lack of knowledge or understanding. And I thank you for your help.

@Anticimex Thnks!

As you can see in the sketch, I'm using a Nrf24L01 module for the node and for the gateway. They are connected to their designed boards (Node and Gateway) respectively. The power, for now, I am doing through the Ftdi232 that I use to connect it to the PC to do debugging. Before adding the signature to the sketch, they were working perfect. What do you suggest doing then?

Also, I have read about the customization of the nodes, but I feel honest I have not managed to understand how to do it ... Could you explain me easily how to personalize it? Truthfully, I have not been able to use the guide.

Thanks for answering me! : D

Hello! I'm new to this and I've been using MySensors to communicate a few nodes in my house with a gateway ... Everything I've done without problems until now that I want to sign the data ...

I have done the following:

1. Ah my sketch (node) simply added the following statement:

#define MY_SIGNING_SOFT
#define MY_SIGNING_REQUEST_SIGNATURES
#define MY_SIGNING_SOFT_RANDOMSEED_PIN A3
(It's a mini pro 3.3 v)

1. My GW added this:
   #define MY_SIGNING_SOFT
   #define MY_SIGNING_REQUEST_SIGNATURES
   #define MY_SIGNING_SOFT_RANDOMSEED_PIN A7
   (Nano 5v)

and already ... everything else I left it still, as I was working.

Now ... This is what the log of my node shows me:
