Thanks you a lot. Now I've changed addresses in ROM and RAM keil's setting like in ble template example and everything goes well.

It's no problem using PWM with BLE. The SoftDevice uses TIMER0, but you are able to use TIMER1 for the PWM. The error refers to wrong settings for the ROM/RAM in Keil; you are trying to put the application code where the SoftDevice is located. With the "ble_app_template" project, you will not get this error, since the settings in Keil are here setup to put the application code on top of the SoftDevice code in flash.

I'll do that. Will I be able to use the same way of working with pwm in ble_app_template saying like in the screenshot above? I know that the softdevice using some timers and some part of flash memory. This error somehow refers with that fact?

The examples located in the peripheral folder doesn’t use BLE. If you want to use the PWM example with BLE, I would recommend to start with the example “ble_app_template” or “ble_app_uart”, and then start to add the code for the PWM in that example.

Thanks for fast reply. I can build "pwm library" example into clear chip without problem. If I install softdevice 132 before I can't build it raise me error: Flash Download failed - "Cortex- M4" (KEIL). It's example locates in NRF5_SDK_12.1.0\examples\peripheral\pwm_driver\pca10040*blank*\arm5_no_packs. I think key of this error is this example locates in "blank" folder. I don't know how to remake this app that I'll be able to build it into chip with preinstalled softdevice

You can use nRFgo Studio(Win32 / Win64) to flash the SoftDevice.

You can find the SoftDevice in

SDK_INSTALL_FOLDER/components/softdevice/

and the SDK(Software Development Kit) can be found here. For nRF52 you need to use SoftDevice S132.

After you have flashed the SoftDevice, use Keil to flash your application.
