[quote userid="71891" url="~/f/nordic-q-a/46833/nrf-connect-can-t-see-nrf52-dk/184745"]I did find that in the IOS version of nRF Connect sometimes a device does not show up[/quote]

Hmmm ... I've just had a client report that!

I had been testing on Android and everything was fine, but they used iOS and it didn't work.

I have started a separate thread on this:

Ok, I redownloaded everything (SDK, nRFgo Studio, Keil 5) and tried again and it worked. Thanks for your help!

What you described looked fine. Please try again on another example. Please also try with the precompiled hex file (inside "hex" folder inside the examples' folder

When testing with precompiled hex file, you don't need to flash the softdevice.

Ok, it looks like I'm getting a

` 71: NRF_LOG_ERROR("SOFTDEVICE: INVALID MEMORY ACCESS"); `.

This is just the example code with no changes.

Here's what I did:

* Erase all

* flashed softdevice with s132_nrf52_6.1.1_softedevice.hex

* In nRFgo studio, programmed application: Desktop/nRF5_SDK_15.3.0_59ac345/nRF5_SDK_15.3.0_59ac345/examples/ble_peripheral/ble_app_beacon/pca10040/s132/arm5_no_packs/_build/nrf52832_xxaa.hex. Programming was successful, but cannot see device.

What I am I missing?

Hi,

Please make sure you flash the softdevice before you flash the application.

Please open RTT log and check if you see any logging. There is a debug guide here.

Please clarify which exact example you tested. Did you test with ble_app_beacon example ? We would suggest you to test with ble_app_hrs and follow the getting started guide.

Hi,

Not that this is a solution to your problem, but I did find that in the IOS version of nRF Connect sometimes a device does not show up. However when I tried with an Android version, it showed up. I possible you can check with the Android app first and see if the beacon shows up.

Hope it helps.
