nRF52840 DONGLE as nRF Sniffer

[Den]

Hi,

I am very happy that we will be able to use the nRF52840 DONGLE as a sniffer with the new update. I thank to Nordic team. This was something I was waiting for. 

However, I am having a problem while configuring the device. I try to load both softdevice (s140 7.2.0) and the sniffer (3.1.0) hex files using nRF Connect v3.6.1 and it gives me an error;

"Some of the HEX files have overlapping data."

Is this a bug regarding the starting address of sniffer hex or am I missing something?

Thanks,

Den

Hi Den,

Glad to hear that:) I've also been waiting for this update. As for the programming problem, the 'sniffer_nrf52840dongle_nrf52840_7cc811f.hex' contains the full FW image, so there is no need to program the Softdevice separately. Please try to program just this file, and let me know if it doesn't work.

Best regards,

Vidar

Hi Vidar,

Thanks for the quick response. I should have missed that fact in the guide. The hex is now loaded to the device. I think I will have to update WireShark before I give it a go. However before that, does the DONGLE need to blink when the hex is loaded? It does not turn on any LEDs. How can I make sure of things?

Thanks,

Den

Hi Den,

For me it starts to blink after I open wireshark. Not sure if it's indicating serial communication or BT packet traffic.

Best regards,
