sd_softdevice_enable hang at nRF52

[Sagisawa Yukichi]

Hi. I'm troubled.

I use nRF52 preview DK v0.9.0 & Keil5. i tried ble_app_hrs_c in example folder of nRF52_SDK.

This program stopped at
err_code = sd_softdevice_enable(clock_source, softdevice_assertion_handler); of softdevice_handler.c.

What's wrong?? Please help me.

Which SDK are you using. The preview kit is only compatible with nRF52 SDK 0.9x

Thanks your comment. I use PCA10040 & V0.9.0.

Check the error code. See this post to see how.

Thanks your comment. I saw your post. But program hangs before output err_code. I think sd_softdevice_enable() is undefined my program. Where is sd_softdevice_enable()?

Hmm. Can you try with SDK 11 and Softdevice S132 V2 ? See the compatibility matrix here. You have Engineering B.
