what are the steps to activate bluetooth on DK???

Yes, of course - exactly as on the DK.

it did not work with the arduino nano 33 ble when I want to test my sensor with the nrf toolbox application it did not work, do I have to activate the bleutooth on the card or it works automatically

So have you got this working first on the DK ?

Again, it's the same nRF52840 chip on both the DK and the Arduino - so the way the BLE part works is no different.

debugging on arduino board is working fine and sensor is working
my problem is to manipulate this sensor via an android application using bluetooth (send data from sensor to the android application using bluetooth)

yes all connections are correct

I'm already debugging on the arduino board

Programming & debugging both use SWD - so if debugging the Arduino is not working, then neither is programming it.

Are you sure you have the connections correct?

The nRF52840 DK needs to detect Vtarget from the external target in order to switch the debugger to the external target

Ok thank you
I have already manipulated the bleutooth on the card and it detects the nrf52840 card and not the arduino nano 33 ble card, the problem is when I debug on the arduino card using the nrf52840 card the arduino card will not be detectable while the code will be uploaded to arduino board and sensors are connect to arduino board ( that is to say nrf52840 board is only use for debugging)

I would strongly suggest that you start with an nRF dev kit to get familiar with the product and the tools.

https://www.nordicsemi.com/Software-and-Tools/Development-Kits/nRF52-DK

www.nordicsemi.com/.../nRF52840-DK

That way, you can use the SDK examples directly - no need to mess with them.

https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.2/examples_ble.html

You don't even need to build anything:

https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.2/getting_started_precompiled.html

Once you are familiar with the product & tools, then you can move on to adapting to "custom" boards ...

how i can connect it with bluetooth on nrf toolbox app

RE: Bluetooth connection between Arduino NANO 33 BLE and Android

In that case, the nRF52840 chip on an Arduino is no different from any other nRF52840 chip on any other board.

I am using nordic SDK (using external debug with arduino nano 33 ble from nrf52840 )

BLE is BLE - Arduino should make no difference.

Are you using the Arduino framework stuff, or Nordic SDK ?

For help with Arduino stuff, you need to go to the Arduino forums
