https://devzone.nordicsemi.com/f/nordic-q-a/44416/zigbee-in-nrf52840Hi everyone I have a question about zigbee. After reviewing the documentation, I realized that on the nrf52840 chip, you can use zigbee with a frequency of 2.4 GHz. But is it possible to use it with a frequency of 868 MHz? This is not mentioned anywhereen-USTelligent Community 13Mon, 02 Mar 2020 10:19:31 GMThttps://devzone.nordicsemi.com/thread/237374?ContentTypeID=1Mon, 02 Mar 2020 10:19:31 GMT137ad170-7792-4731-bb38-c0d22fbe4515:77ee8df3-f9de-483d-9088-5a6dacd5635dSimonr<p><span>No, it can communicate with other Zigbee products at 2.4GHz.

The zboss stack is just a generic zigbee stack and is used in most Zigbee products, which is why that function is present. The nRF52840 should however be able to communicate with other Zigbee products supporting both 2.4GHz and sub-GHz frequencies.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
