Instead of NRF_TIMER2->TASKS_STOP = 1; try this maybe:

  // Errata: [78] TIMER: High current consumption when using timer STOP task only
  //  - Workaround: Use the SHUTDOWN task after the STOP task or instead of the STOP task
  //  - this also stops the Timer from hanging after a time change
  //  - affects nRF52832, nRF52840
  NRF_TIMER2->TASKS_SHUTDOWN = 1;
  // There is no STOPPED Event, and this register is read-only, so add a delay to ensure it is stopped before changes
  //NRF_TIMER2->TASKS_STOP = 1;
  nrf_delay_us(200);

Not sure about priorities in Arduino, but maybe set something:

  // Set interrupt priority and enable interrupt
  NVIC_SetPriority(TIMER2_IRQn, 6);

Edit: Oh, I see the question is 8 months old, maybe it got fixed already ..

Of course there is.

You can just erase the chip, and go from there ...

Hey there! I'm wondering the same thing. I'd like to use an official Nordic SDK on the nano 33 BLE. Is there a way to do this?

Do you believe that is possible to develop on nrf SDK and then flash the hex file to arduino nano ble 33 through SWD pins?

I have also bought a few boards supporting the nRF52840 Nordic chip that I would prefer to program using nordic's nrf-connect. Which I think could be done, just no one has done it. In my case both the Arduino Nano 33 BLE and the Particle Mesh devices. As far as I can tell, neither can be programmed using the USB connection and nRF-connect.

Yes, but nordic have nothing to do with the Arduino software that you're using to drive it - that's the bit that you need to ask the Arduino people about.

Nordic support development using their SDK:

With the kindest of respect this arduino does it uses the Nordic nRrf 52840 nmicroprocessor so I thought it might be a good place to ask

The Arduino stuff is nothing to do with Nordic - you'd need to ask on the Arduino forums
