Hi @bereska, welcome to the MySensors community
For next time, could you put the code in a code box? Instructions are available here. I took the liberty to fix it for you this time. Please also use the Auto format (ctrl/cmd+T) feature in the Arduino IDE, which makes it much easier to read the code.
https://forum.mysensors.org/topic/666/debug-faq-and-how-ask-for-help/ has information on the most common problems, and how to troubleshoot them.
The log parser can help understand the log messages.
The log you posted shows that the gateway is receiving messages from node 1, but there is nothing from node 22. The deubg log from node22 will probably give information on why it is having trouble.

Hi @mfalkvidd
thank you for your prompt reply
I promise i will follow the rules
i'm very new to this, please bear with me)
I've spent all this time studying logs and trying different nrf24 radios (standard & LNA), but no dice(
please help
