"Undefined reference to [functions]" errors even though I have included the relevant H files.

That should do it. I added #include lines and had not added the C files to my project, so it had no way of accessing them.

Thanks so much!

Did you remember to add the c file to your project?

Thanks for the suggestion! I defined that macro in my sdk_config.h and will do the same for the other ones that should be set. However, the current errors persist.

This may help narrow down the problem further: when I try Ctrl+O and look for nrf_ble_gatt.c, it says the solution file does not exist in the project. So it's not that the module is enabled; it just doesn't access the C files.

Hi,

A typical reason for such issues with the nRF5 SDK if you have included the requiered files is that you have not enabled the module in sdk_config.h. For instance, for nrf_ble_gatt_init() to be included you need to set NRF_BLE_GATT_ENABLED to 1 in your project's sdk_config.h file.
