I just bought a second CUL device from here:

https://www.amazon.de/-/en/gp/product/B07T26ZSZG/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1
https://www.smart-home-komponente.de/nano-cul/nano-cul-868-extern/

The manual says that i should find the device under /dev/serial/by-id/usb-SHK_NANO_CUL_868-if00-port0@38400 0000 but i comes up as:
[...]
Can anyone give me a hint on how I can flash the device.

You should do a reclamation also involving amazon, see https://www.voltlog.com/tag/ft232-a50285bi/ for details why.

The seller ("smarty") is one of our "well-known customers" here causing trouble with not well designed products every now and then. Very unhappy to see, he is getting back to old behaviour...

Thanks for this information. This is really disappointing and I can verify that I have a fake since the serial is A50285BI

I could actually flash the device by changing the baudrate:
avrdude -D -p atmega328p -P /dev/ttyUSB0 -b 115200 -c arduino -U flash:w:nanoCUL.hex

Hello again. I have both a CUL  from Busware (CC1101 - USB - Lite module - V3) and a nanoCUL which both work fine. I have been using them to sniff the bus traffic and sync the state of my Gira lights with Home assistant, but controlling the lights via an XS1 from Ezcontrol.

Now i have been playing with the CUL to control the lights, but I cannot figure out the dimming.

I can turn on/off and completely dim up or down, but have not figured out the stop command. My understanding is that I should send a command to dim (eg UL) and then a stop command (S0) to stop the dimming but all my permutations and timing has not worked.

Here is an example of a command I send to dim to 100% brightness:
Js4355D6BA1UL

That gives me the following sequence:
J4355D6BA1UU00
J4355D6BA1U100
J4355D6BA1U100
J4355D6BA1U100
J4355D6BA1UL00
J4355D6BA1UL00
J4355D6BA1UL00
J4355D6BA1UL00
J4355D6BA1SL00
J4355D6BA1SL00

Then I have tried to stop the dimming (for example at 50%) with this commands, but none seem to work for me:
Js4355D6BA1SS
Js4355D6BA1SL
Js4355D6BA1S1
Js4355D6BA1S0

I see that there are some versions of the firmware and maybe dimming is not supported with all of them? I tried to flash a different version, but it got me nowhere. I´m currently on the firmware from reply #110: nanoCUL.hex (MD5 > fa69b2683822bc275f28e9c1e0228cb0)

Can someone point me in the right direction - thanks
