@frits I'm using a cc2652rb USB-Stick and I was flashing it via USB.

@frits thank you, I tried to flash the ptvo firmware, and after flashing I found out that the firmware does not contain a boot loader. So my zigbee stick is lost...

Thank you!
He is working with windows software (IAR)?
This is funny :-)

I have built some sensors with wifi based on esp8266/esp32.
Now I would like to build my own zigbee sensors.
Are there any programmable zigbee modules with I/O pins?
