The allowed voltage range is 1.7–3.6 V. It should work if you give 3.6V.

this external supply given 3.6 and I need 3.3
Is that work correctly?

I don't have 3.3V power in my DK
does it work with 5V power ?

Please provide power to nano 33 and confirm by the J-Link Commander as this figure (https://wiki.segger.com/File:nano33_BLE_Connect.png).

no I did not use this debug
I connect the external debugging pins of the NRF52840 card which corresponds to the P20 pins with the pins of the arduino nano 33 ble card

No, the Debug out connector (P19) on the DK. See Debug output.

what does that mean i didn't understand
do you have to connect pin 19 of the NRF52840 card with a pin of the arduino nano?

Hi,

[quote user="nikola "]the power of arduino nano ble is connected to VTG pin of the NRF52832 (VTref==>VTG) [/quote]

Do you connect via Debug out (P19)? The VTG doesn't provide power to the external device. You need to provide power to nano 33 and confirm by the J-Link Commander detect the VTref is 3.3v. If you connect correctly, you could start to debug to see why the application cannot work on nano 33. You might need help from https://forum.arduino.cc regarding how to debug on nano 33. Also, check out https://wiki.segger.com/Arduino_Nano_33_BLE

The NRF Toolbox application poster No device Found , my intention is to send and receive data from NRF52832 using debug out with arduino nano 33 ble

Are you using the DK to program and debug Arduino NANO 33 BLE via Debug output? Do you also provide power to NANO 33? Could J-Link Commander detect the VTref is 3.3v? [/quote]

the second DK is the NRF52832 .
yes I am using the DK to program and debug Arduino nano 33 ble via debug out .

the power of arduino nano ble is connected to VTG pin of the NRF52832 (VTref==>VTG)

See this Debug output doc. Please also check the SWD connection is correct.
