What problem did you encounter? What errors are you seeing? What do you mean by "defined the definition related to transplantation"?

If you read the comments, you see how the issue was solved.

Thanks. One thing I can't clearly understand is this raw:

p_nus->data_handler(p_nus, p_evt_write->data, p_evt_write->len);

Couldn't you brevity explain

On a write to the characteristic, you will get a BLE_GATTS_EVT_WRITE event in the BLE event handler for your service. Here you can handle the newly received value and assign it to the PWM interface. Have a look at the ble_app_uart example, especially the ble_nus_on_ble_evt() and on_write() functions in ble_nus.c file, to get an idea how this can be handled.

Thanks a lot. I didn't know about sdk_config things). After I write new value to my characteristic (from nrf_connect app) how can I refer to that written value from main.c for adding to pwm set function? Should I create new extern variable in pwm_service.h file?

Did you enable app_pwm in sdk_config.h? #define APP_PWM_ENABLED 1

Thank you. It's worked now. but I have such errors:

._build\nrf52832_xxaa.axf: Error: L6218E: Undefined symbol app_pwm_channel_duty_set (referred from main.o). ._build\nrf52832_xxaa.axf: Error: L6218E: Undefined symbol app_pwm_enable (referred from main.o). ._build\nrf52832_xxaa.axf: Error: L6218E: Undefined symbol app_pwm_init (referred from main.o).strong text

app_pwm.c added to nrf_library

Did you also set #define TIMER_ENABLED 1 in sdk_config.h?
