Hi,

Seek your kind recommendation what debugger; both hardware and software, i need.
I have bought three of Sparkfun Pro nRF52840 Mini to experiment building up BLE peripheral and central experiment on ble_app_hrs_rscs_relay.

Am following this guide: learn.sparkfun.com/.../nrf52840-advanced-development-with-the-nrf5-sdk and i have been searching for the most appropriate tools to debug my code.

I cant find any guide specific to this board, for debugging, taking into the consideration of the compiler (gcc) and editor (VS Code) used.
Is there a way round it, to debug the code without additional gadgets/hardware?

nRF52 have SWD only - not JTAG.

Any debug probe which supports ARM Cortex-M4 and SWD should work - but, if you want to use something unsupported, then it will be up to you to work out all the details of how to configure it & how to use it.
