RF not working in nRF52 DK (nRF52832_xxAA_REV3)

[Prerana Diwani]

Hi all,

I'm currently working with the nRF52 DK (nRF52832_xxAA_REV3) using the nRF5 SDK version 17.1.0_ddde560 and the IAR Embedded Workbench - Arm 8.32.3 IDE. I'm facing an issue with the RF part not working in the ble_app_blinky example code located at:
nRF5_SDK_17.1.0_ddde560\examples\ble_peripheral\ble_app_blinky\pca10040\s132.

Before flashing the ble_app_blinky example, I have already flashed the SoftDevice S132. However, when I flash the ble_app_blinky example, it seems to hang on the sd_softdevice_enable() function during debugging and never progresses. On the other hand, when I flash the blinky example (from nRF5_SDK_17.1.0_ddde560\examples\peripheral\blinky\pca10040\s132), it works fine without any RF functionality.

Has anyone encountered a similar issue or can point out possible causes for this hang when enabling the SoftDevice? Any suggestions or troubleshooting steps would be greatly appreciated!

Thanks in advance for your help!

It sounds like the SoftDevice might not be properly flashed. Have you verified that the SoftDevice is correctly written to flash before flashing the application?

yes, I have read flash with nrf connect desktop after flashing soft device. so, I'm certain sure SoftDevice is correctly flashed before flashing the application. I have test this with multiple iterations.
