Error (NRF_ERROR_TIMEOUT) when using nRF Connect

[RSA]

Hi, when following the tutorial, https://devzone.nordicsemi.com/nordic/short-range-guides/b/bluetooth-low-energy/posts/ble-advertising-a-beginners-tutorial i ran into problems.

I running and building/flashing to the nRF52840 DK (using segger and SDK 15.0.0 without any noticeable issues.

The problem appears when using "Connect v 3.1.0 Bluetooth low energy"

i've made sure to test my UART in other projects (as mentioned in https://devzone.nordicsemi.com/f/nordic-q-a/28729/nrf-connect-error-nrf_error_timeout).

I haven't followed the " nRF Connect getting started assistant" since im using  the fore mentioned SDK, hopefully this doesn't cause any issues?

Update: i have know tried to flash the 140 softdevice on it's own.. the connector works this way, meaning that the connection is solid.. But the Issue at hand remains.

Hi

Please try erasing the program on your device, either using nrfjprog or the programmer app in nRFConnect and try connecting using the Bluetooth Low Energy app again. You should get a pop-up saying: Device must be programmed, do you want to proceed? Confirm this, and see if you're able to connect successfully. 

Also, please upload the log you see when you get this error message, so I can have a better look at the error messages. You can press the Open log file button (third from the right in the bottom right corner) to open a log file and upload that.

Best regards,

Simon

Encountered same error, solved after erasing program.

It would be better if Bluetooth Low Energy app can detect firmware compatibility issue and give a pop-up.
