 ## Overview
 
+## Setting up nRF Connect SDK
 
+## Install NCS
+Please see:
+https://developer.nordicsemi.com/nRF_Connect_SDK/doc/2.6.0/nrf/installation/install_ncs.html
 
-## Setting up nRF Connect SDK
+To initialize nrf belov command instead the one mentioned in instruction:
 
-Install NCS
+`west init -m https://github.com/nrfconnect/sdk-nrf --mr collab-serial-ble-ot`
 
 ## Building application
 
-
 ## Flashing and connecting
 
 ## Testing
 
+### Testing BLE
+
+In order to test BLE You will need to install `nRF Connect for Mobile`
+
+ - IOS: https://apps.apple.com/pl/app/nrf-connect-for-mobile/id1054362403
+
+ - Android: https://play.google.com/store/apps/details?id=no.nordicsemi.android.mcp&pcampaignid=web_share
+
+On client site please invoke in zephyr shell:
+```console
+ > bt init
+ > bt advertise on
+```
+
+On mobile Phone open `nRF Connect` app and scan for: `Nordic_UART_Service` as in image below.
+
+<img src="resources/nrf_scan.jpg" alt="image" width="300" height="auto">
+
+Tap connect.
+
+This will connect to nRF52 and You should be able to see in zephyr Shell similar message:
+
+```
+LE conn param updated: int 0x0027 lat 0 to 42
+```
+
+To Send Data from your phone tap arrow next to Rx characteristic.
+
+<img src="resources/nrf_send.jpg" alt="image" width="300" height="auto">
 
-###
+On `nRF52` you should see:
 
-Testing BLE
+```
+bt_nus: on_receive: Received data, handle 0, conn 0x200023c4
+```
