Hi,

I tested your code and think I found the issue. In addition to incrementing NRF_SDH_BLE_VS_UUID_COUNT you need to allocate more RAM to the Softdevice. The way to figure out how to do this is to use a serial terminal when you debug your project. When your code executes nrf_sdh_ble_enable() these messages are printed out:

Then open your linker script and edit the RAM sizes accordingly:

To make debugging easier you should also use optimization level -O0 (instead of the default -O3) and define

CFLAGS += -DDEBUG

in the C flags in your Makefile.

EDIT: After I made these changes to your code it seemed to work. Note that you will probably have to make more changes to RAM sizes as you expand your project with more services and characteristics and if you tweak the Softdevice link and bandwidth settings. So be aware of that.

Here they are 🙂 These are main.c and the own_service.c and .h. These are the only files I manipulated and added to the project.

Maybe we can start with just the .c and .h files that you use.

Hi,

I've incremented the value from 0 to 1 and tried again, but still got the hard fault. I've tried to upload my project, but it didn't work also. I thing it's too big (zipped 12MB). Can I upload in another way?

Thanks for the support!!

Hi,

If you are adding a second VS UUID, make sure to increment NRF_SDH_BLE_VS_UUID_COUNT in sdk_config.h. I needs to match the number of VS UUIDs in your application.

I'm a little puzzled that you get a hard fault though. If the issue was a wrong value in NRF_SDH_BLE_VS_UUID_COUNT I'm pretty sure that sd_ble_uuid_vs_add() should only return an error code that you would typically check with APP_ERROR_CHECK(err_code);

If this is in order, do you mind uploading your project files?
