    Hello Manjunatha GN, 

    In order for the CC2340R5 to work with external power please connect PWR and Ground (3.3 V + GND). Do you still want to be able to debug in this configuration? Here is a snippet, CC2340R5 LaunchPad (ti.com)

    "Power supply requirements:

    The LaunchPad is designed to be powered from the LaunchPad EM Debug Probe via the LP-EM Debug connector, or from an external power supply connected to the GND and both 5V & 3V3 pin headers. When powering from the LaunchPad EM Debug Probe, the device supply voltage is fixed in 3.3 V. When powering externally, care must be taken to keep the board voltage within its operating range (1.8 V to 3.6 V). "

    Thanks,
    Alex F
