Bluetooth connection between Arduino NANO 33 BLE and Android

[nikola]

Hi ,
How can I connect arduino nano 33 ble with the application NRF Toolbox using Bleutooth when I program the arduino with segger embeded studio .

Please I need your help.

thank you

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

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

how i can connect it with bluetooth on nrf toolbox app

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

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

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

You don't even need to build anything:

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

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)

So you do have an nRF52840 DK, you have code working on that, and now you're trying to use it to program & debug 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

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

[awneil]

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.

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

[awneil]

Again, take a step back and get it working on the DK first!

nikola said:

do I have to activate the bleutooth

Yes, of course - exactly as on the DK.

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