[yellan]

Hi;

 I program pca10059   for sniffer to grep some packet,now i want to revert to dongle,but i can't find the precompiled application firmware examples in the nRF5 SDK.

 I have downloaded the sdk of "nRF5_SDK_17.1.0_ddde560",Could you show me the correct directory for the "nRF52840 dongle firmware" which described in the info center.

Best regards,

yellan

Hi,

I'm not sure I understand exactly what you mean by "revert to dongle". The Dongle can run many different firmwares, based on which application it is used against. If you use the dongle together with nRF Connect for Desktop applications, the applications should automatically program the dongle with correct firmware (if not detected on the dongle). If you have programmed an application that does not enable automatic entering of bootloader mode through USB, you might have to press the reset button on the dongle to enter Bootloader mode (LED should "breathe" red). See the nRF52840 Dongle Programming Tutorial for more details.

Best regards,
Jørgen
