Hello,

Order yourself an nRF52840-DK if you haven't already. The amount of time you will save by using the DK for programming and debugging far exceed any kind of development you can do on the nRF52840 USB dongle. The nRF52840 USB dongle is fine to use with our nRF Connect for Desktop app to for instance act as BLE central device, or as on-air BLE sniffer, or even for demo final products, but for development you should be using an nRF52840-DK. You can even program the nRF52840 USB dongle from the nRF52840-DK if you want.

Best regards,
Kenneth

hi kennath thanks for the reply, 

I'm working on an asset tracking project and would prefer to use a USB dongle due to cost and size constraints. My main goal is to test whether I can successfully read a unique ID from a beacon, evaluate power consumption, and check signal penetration. If everything works well, I'll proceed with sample fabrication.

Currently, I have successfully flashed the proprietary ESB RX and TX code onto two devices using nrfutil. However, I'm not receiving any output, and I'm unsure why. My concern is whether the proprietary ESB RX/TX example in the Nordic SDK is specifically designed for the nRF5340 DK. Could it be that the internal pin configuration differs between the USB dongle and the DK, causing the issue?

Any insights or guidance your would be greatly appreciated!
