nrf_sdh_enable_request() error

[JGusler]

I am running the BLE_APP_UART example on a custom board. When I get to nrf_sdh_enable_request() in ble_stack_init(), I get the error code of Invalid state, meaning the sdh is already enabled. I'm not sure how that is since it's a fresh build and run on segger, but whatever. I decided to work around this by DISABLING the sdh right before this with nrh_sdh_disable_request(). When I did this, it ALSO returns Invalid state, meaning the sdh is disabled already. So the functions are in complete disagreement with each other. What am I doing wrong here in my setup of the softdevice to cause such an issue?

Hi,

I think you might be running into the behavior discussed in this post:  NRF52840 SDK 16 - nrf_sdh_enable_request returns [NRF_ERROR_INVALID_STATE]

Okay, should I then be merely building and then Downloading under Target?

[Sigurd]

Yes, try that, alternatively, "build & debug" and abort debug session.

[JGusler]

With the Target Download option, using either debug or release build, i now get no output at all

What SES version are you using?

I recommend using the version we used for the release testing.

E.g. for nRF5-SDK v17.1.0, we used SES 5.42a

I was able to get it with the #define NRF_FPRINTF_FLAG_AUTOMATIC_CR_ON_LF_ENABLED 0 define issue and using nrfjprog to flash the board.

I'm using SES 6.34a
