Making nrf cli application softdevice aware

[Anantha Keshava]

I'm attempting to make cli application to load from after the softdevice and based on a command enable/disable the BLE functionality. Is there any simple way to do this? Are there any known challenges to this kind of usage?

I have so far done the following changes:

• Makefile:

Replaced SDK/components/drivers_nrf/nrf_soc_nosd/nrf_nvic.c  and SDK/components/drivers_nrf/nrf_soc_nosd/nrf_soc.c with SDK/components/softdevice/common/nrf_sdh.c and SDK/components/softdevice/common/nrf_sdh_soc.c

Added the following flags

CFLAGS += -DSOFTDEVICE_PRESENT

CFLAGS += -DS140

ASMFLAGS += -DSOFTDEVICE_PRESENT

ASMFLAGS += -DS140

• gcc_nrf52.ld:

replaced contents with example for ble_app_hrs equivalent linker script file.

• sdk_config.h:

#define NRF_SDH_ENABLED 1

#define NRF_SDH_SOC_ENABLED 1

Currently when I run this application, I see the application hits hardfault at random places depending on how far I step through and allow to run.

Hi, 

Looks like you have performed the necessary changes already. The hardfault might be explained by the fact that you single step through the code, see "How can I debug a softdevice application". 

The Experimental: BLE Interactive Command Line Interface Example might be a better starting point if you want to create a BLE application with CLI support, or have you tried it already?

Hi Vidar Berg,

Thanks for the response. I saw the cli not coming up which was why I started debugging. I believe the Hardfault is hit no matter whether I initialize the Softdevice or not.

I'll attempt the other example suggested by you. I was only hoping not to port all of my other commands I had written on the cli example to another version.

I have gone through the process of adding the softdevice to the CLI project previously, and don't see anything missing in the steps you outlined. Maybe you can use Hardfault handling library to determine what triggered it (remember to include both hardfault_handler_gcc.c and hardfault_implementation.c).
