QN9020 mini DK user guide

2.4 SEGGER J-Link OB part

The SEGGER J-Link OB offers the SWD and UART interface. Users can download or
update firmware into a QN9020 device by using the UART or SWD interface.
Furthermore, it is convenient to debug the program for a QN9020 device using SWD
interface.

To program or debug the QN9020 device using the SEGGER J-Link OB, the 0
