When you call sd_app_evt_wait() in power_manage() you will wait for events from the SoftDevice, you will not be running in the for loop. The counter will only increase when you events from the SoftDevice. If you (after you are connected) put a breakpoint at ble_nus_string_send() inside the if you will see that you never hit it. If you comment out power_manager(), you can see that notifications are sent all the time.

ble_nus_string_send() outside the if will be called because when the notification is sent you will receive the BLE_EVT_TX_COMPLETE event, which will trigger a new call to ble_nus_string_send().

project files are uploaded, softdevice is also in it, but I did not find the SDK version. I will try to get the error code later. Thanks

Also use the debugger to check the returned error code of ble_nus_string_send(). Remember to turn off optimizations.

Edit your question and click the paper clip button. It says attachment. Zip your complete project folder, ble_app_uart, and attach it. What SDK are you using? Check release_notes.txt in \documentation

sorry, but I am not sure how to upload the whole project files here.

the project is based on demo project ble_sdk_uart_over_ble, soft device is s130_nrf51_1.0.0

Can you check the returned error code of ble_nus_string_send()? Is it NRF_SUCCESS (0x00000000)? I can also test you code here, if you edit your question and upload the complete project, and includes what SoftDevice and SDK version you are using.
