You haven't said what IDE you're using.

But it looks like Keil?

You mean like this:

If so, note that uVision will also be giving you extra information in the 'Output' window:

So what is that telling you?

Have you changed the linker settings so the application starts above the Softdevice? The current memory layout is shown in 'options for target -> target' in Keil.

Hi,

These symbols are defined in nrf_sdh.c. Also, make sure to include nrf_sdh_ble.c nrf_sdh_soc.c as these are needed for forwarding of Softdevice events to various SDK modules such as fstorage. See the SoftDevice Handler library for more details.

Edit: it's probably easier to merge TWI into the ble_hrs_freertos example than it is to merge freertos and BLE into an example that doesn't use the Softdevice.

You need to define those symbols!

Take a look at one of the unmodified projects to see where they should get defined.

Most likely, you have omitted some sdk_config.h settings, and/or adding some source files to your project ...
