nRF5340 PDK not advertising

[LeoChen]

Hi,

I order one nRF5340 PDK from Mouser.

I am following the get started document.

https://infocenter.nordicsemi.com/topic/ug_gsg_ncs/UG/gsg/first_test.html?cp=1_1_2_3

However, the PDK never advertises and RTT viewer does not show any log.

nrfjprog 10.6.0

JLinkARM.dll 6.60e

APP: nrf toolbox, nrf connect for mobile.

Phone: SamSung Note10

Have any idea?

Thanks.

Hi,

Please reset the PDK by pressing the SW5 or run "nrfjprog --pinreset" the again before the nRFConnect/Toolbox scans device.

Hi,

Already did hardware/soft reset many times to try.

Hi, 

What is the status of LED5?

Did you see nRFConnect discover the PDK as "Zephyr Heartrate Sensor" in the scanner frame?

In the nRFTool, Seems that on Android the location is changed a little bit and FINE_LOCATION permission is required for BLE but the app only receive COARSE_LOCATION permission which is not enough. The trick is to go to App settings -> Permission -> Location Permission and click Deny then click grant again. This should make it works.

Hi,

The following video shows the LED status and nRFConnect scanning of my PDK.

https://www.dropbox.com/s/cnsfndns9i8ai86/nRF5340%20no%20advertising.mp4?dl=0

I have 5 PCA10040, 6 PCA10056, 3 PCA10059 and hundreds of Fanstel modules.

All of them can discover by APP.

So, I do not think the problem is caused by APP.

I saw PCA10095 print "***** Booting Zephyr OS build v1.14.99-ncs3-snapshot2-1329-g6d7f8d05df81 *****<CR><LF>" to UART after reset.

Thanks for your help.

Hi Leo, 

Please open the command line and run 'nrfjprog --eraseall' and 'nrfjprog --recover' and then reprogram the images. In the UART, you will see like this after reset.
