And my settings are seen in previous posts.
But this does not lead to anything so I finish this now.

@dpressle

I can burn Mysbootloader yes.
But the Atmega circuit does not start.
The problem I think is that Mysbootloader does not use the internal clock

And because you said you had a bootloader for OTA and internal clock, 8MHz I wanted you to send it to me.

Then there would have been no problem, I think.

Feeling a bit confused how do you know that a bootloader uses the internal clock?
Because I used another bootloader after installing your card, I did not get the Atmega circuit to run. But if I used this bootloader, I started the Atmega circuit and everything worked.

Https://forum.mysensors.org/topic/3018/tutorial-how-to-burn-1mhz-8mhz-bootloader-using-arduino-ide-1-6-5-r5

But what makes the internal clock in used?
I use a UNO when I'm burning bootloader and do not know if you can change fuses and clock option.

If you use a bootloader that uses an external clock, you will not get the Atmega circuit to run. If I understand everything right.

No if I'm burning 8MHz Mysbootloader, the Atmega circuit does not start.

But instead, I use this bootloader (ATmega328 on a 8 MHz internal clock) and I get the Atmega circuit to run, but without OTA.

Https://forum.mysensors.org/topic/3018/tutorial-how-to-burn-1mhz-8mhz-bootloader-using-arduino-ide-1-6-5-r5

Therefore, I asked you how to know how a bootloader uses an external clock or internal clock.

The problem is not to burn bootloader. The problem I think is that the Mysbootloader does not use internal clock.

I do not get Atmel to run with Mysbootloader 8MHz.
Seems like it does not use the internal clock
Also tried to put your text into the board.txt file without any difference.
But if I use the bottloader ATmega328 on a breadboard (8 MHz internal clock it work.

@dpressle
Ok first, I have to say that I have no problem getting your project to work. It connects directly to HA. What I get a little confused about is that according to the link I linked to it says.

Be sure to select "ATmega328 on a breadboard (8 MHz internal clock)" when burning the bootloader.(If you select the wrong item and configure the microcontroller to use an external clock, it won't work unless you connect one.)

And as I interpret your post, you can take whatever bootloader you want (8 MHz).
And if I understand you right now, all settings iis n the board.txt file?

@livinlowe

It depends a little on what you want to do, but at first it is enough. However, if you want to use MySensor's example using external libraries, you will also need to download this link.
Https://github.com/mysensors/MySensorsArduinoExamples/archive/master.zip

For example, DHT 22, which measures temperature and humidity.

//Mattias

@dpressle

Does the bootloader use the internal 8 MHz clock?

//Mattias

@dpressle

Can you email it to me or maybe add it to your project.

//Mattias

@dpressle

Ok tanks

Do you have a bootloader with OTA enable

//Mattias

What version do you have of IDE? In newer versions, you install the MySensors library in IDE

//Mattias

Something new about OTA and MySensors 2.1.1 with atmega328P-PU 28 DIP 8MHz internal clock?

//Mattias

Where can you find the code?

@cadet

I'm no expert but I would have looked at the data sheet and measured up to make sure that the hardware are not defective in any way.

http://ww1.microchip.com/downloads/en/DeviceDoc/39662c.pdf

Or the radio.

//Mattias

@cadet

There I can say is that the circuit ENC28J60 works with MySensors lib 2.1.1
Try to connect your components to breadboard.

@cadet

Ok, you have linked NRF24 radio right?

https://www.mysensors.org/build/ethernet_gateway#enc28j60-ethernet-module

Also verified that the shield is properly attached?
//Mattias

@cadet

Yes, I put together this some years ago. But now i uses W5100 instead.
