nRF5280 LED5 always on after installing demo programs

Hi Simon,

I managed to find this:

https://devzone.nordicsemi.com/f/nordic-q-a/32130/nrf52-sdk14-2-ble_app_uart-peripheral-example-not-working

Presuming the GATT table wasn't quite right, I restarted Bluetooth on the phone. Once again, the age-old method of turning it off and on again has prevailed; can't believe I didn't try this before!

Everything works as intended now, I'm just working on trying to manually dim the LEDs myself as the dimming example demo won't compile (I think there's a problem with SDK paths on my machine), but that will be for a new question.

I'll mark this as answered, thanks for all your help!

I do not have any problems using an iPhone 6, with the latest nRF Toolbox app from the App Store, so I do not see why it shouldn't work on your iOS device. What iOS device are you testing with?

Best regards,

Simon

Hi Simon,

After further investigation online, it appears that the Android App works FLAWLESSLY, whereas the iOS app only has this problem. What device are you testing this on? Do you know why this might be?

Both devices are using the latest version of the nRF Toolbox app from the Google Play and App Store.

Kind Regards,

Lewis Kosztan

Hi Lewis

The alarm will trigger on the phone. You may have to allow the phone app access to notifications and sounds etc. for these functions to work properly. You should not have to add any other .hex files when flashing.

Best regards,

Simon

Hi Simon,

Progress! The name of the hex file that I had did not match up to the one you've provided. However, I did get my version from the front-page downloads for the nRF52840, and I had to go through a lot of documentation to find a download link to the SDK I needed. I have currently got the nRF5_SDK_15.3.0_59ac345 SDK.

Now, LED1 blinks when advertising, and stays solid when paired. Holding button 1 will disconnect the board from the phone, and I can also disconnect via the phone. Pressing button 1 when advertising will put the board into sleep mode. Great!

However, LED3 doesn't blink when I press the 'FindMe' button on the phone, and pressing button 1 does not trigger an alert on the phone.

There must be something else I'm missing. Is there anything else I need to flash to the board? Currently, I'm only writing the ble_app_proximity_pca10056_s140.hex to the board; nothing else. Is there anything else I need to add in the flashing process? It may be something related to softdevices; I'm not sure what those are so I haven't done anything with them.

Also, where is this alarm? I can't see one on the board...

Thank you for all your help so far!

LED5 is on as long as the board is powered, it is connected to the debugger, and is on as long as the board is powered (Blinking while flashing the chip). However, I just tried the proximity example myself and did not experience any faulty LEDs. LED1 blinked when advertising, stayed on when connected, and LED3 could be toggled with the "find me" button. The alarm is also working (a lot of startled colleagues can confirm that).

So I'm not sure what is going on on your side. What SDK are you using? And what .hex file did you write to the chip? ble_app_proximity_pca10056_s140.hex is the correct one.

Best regards,

Simon
