Okay i found my problems.

One of my nrf24 board seems to have an defect. It does not send anything but receive works.#
After i've changed my nrf24 board, the node appeared just after burning the bootloader at my gateway.
Flashing via ethernet gateway (Arduino uno and w5100 board) was not possible.

I figured out, that lot of people have trouble with this, because the arduino reboots very often.
After updating to mysensors lib 2.2.0-beta this was better, but mostly my ethernet connection was lost during ota firmware update.
-There are lot of interesing things, that problmes came up with avr board revision 1.6.8. Also some problems are there with an resistor. I've no idea if the resistor problem occures only with newer board revisions.

I got my ethernet problems solved, with removing the sd card from the ethernet shield. I did not used it, it was there from an older project. No really idea, whats up with that sd card, but without an sd card connected, i was able to update my sketches.

I also used the bootloader from MySensorsBootloaderRF24-development and figured out that this one is needed to reassign the id.

When i burn a sketch in the node, it hangs after sending the ota flash command.

Same occures if i send a reboot command.

How do i have to flash the sketch the first time?

Hi,

I've connected mysyscontroller and rebootet the node after i reconnected the nrf radio chip.

But the node has only the bootloader, it has no sketch installed.

The radio works, because the gateway receives data. The postet log in my post #1 repeats endless and is shown in captured from the mysyscontroller .

I've burned the mysensors bootloader onto a arduino nano.

I see in the debug output from my gateway (serial and ethernet tested) that there is a communication between the node and the gatway.
But the node is not registered in the mysyscontroller tool. So how can i upload a firmware to that node?

That is, what i can see in the debug log:

0;255;3;0;9;TSF:MSG:READ,255-255-255,s=255,c=3,t=7,pt=1,l=1,sg=0:0

avrdude done. Thank you.```

I've also tested the mysensors bootloader from the development branch, but that wasn't better.

I hope someone has an idea, whats going wrong.
