No errors for the Genuino now and the scanner prints out the code needed for the Feather nRF52 bridge sketch so that it will connect to the The scanner will check every device it finds in range. The scanner does not stay connected to the device so its Blue led is usually flashing.
Near the top of that sketch you will find the following code. Replace the three lines of code with the output from the scanner for the BLE device you want to bridge to. When the connection is made to your BLE device, as described above, the Blue led will light up constantly and the Red led will flash once every 10sec or so. This lets you not the connection has been make and being maintained. Then in the Serial Monitor you can enter the commands you expect to send to your BLE device and watch it operate and monitor any response it send back.
If the scanner cannot find you BLE device it is either too far away or not advertising or already connected to something. Try moving the scanner closer and power cycling the device and turning off all other near by mobile devices that may have a connection to the BLE device. None found OR Not discoverable! Try moving closer to the BLE device. That app has better range and sensitivity. However you will still need to get the scanner to run and connect and identify the Nordic UART Serivice before you attempt to use the Wifi2BLE bridge as it uses code similar to the scanner.
If you want to dig deeper you can also use the Adafruit Bluefruit LE Sniffer module to see what is in the air. If you managed to scan the BLE device then the most likely causes of connection problems are I the BLE device is too far away OR just on the edge which can give intermittent connections.
II something else has already connected to the BLE device. Try powering down all your computers and devices and power cycling the router leave it off for 20sec and then scan with Fing again. The project presented here is the simplest version. There are a number of possible extensions such as The Feather nRF52 is capable of connecting to up to 4 BLE devices at once so you could modify the code to add more valid addresses and control up to 4 devices from the one WiFi connection.
See the example code that comes with the Feather nRF52 board install. You could punch a hole in your router to provide access to the BLE device from anywhere on the internet. You would need to add a configuration push button to the circuit. To save the result, you will need to use the nffs library that comes with the Adafruit nRF52 board install.
That indicates it has successfully connected to your local network and started the server to accept a connection. When you connect the Red Led on the module should start flashing, indicating there is a connection. You should now be able to type into your computers terminal window and the characters should appear in the Arduino IDE's monitor window and vis versa. This ensures the module recovers from 'half closed' connections which happen went the client just disappears due to bad WiFi connection, power loss at the router or forced shut down of the client.
This connection time out is set to 60 sec. Setting it to 0 means never time out which is not recommended. Check you can connect to, and program the board via the USB cable. This is a two step process. The free pfodDesignerV3 allows you to create pfodApp menus and then generates the Arduino code necessary to show that exact menu on your Android mobile using paid pfodApp.
However this is just an example and you do not need to purchase pfodApp to complete this project. So lets scan for it. The Bluetooth Committee bares the blame for this for not specifying a 'standard' UART Service, instead leaving each manufacturer to make up their one.
As covered above the code was generated by pfodDesignerV3 primarily for use with pfodApp. The second line is just a description of the characteristic and does not effect the operation.

You could also use pfodDesignerV3 and pfodApp add a custom interface with no changes to this project at all.
The simple construction and the detailed testing instructions makes this a suitable project for beginners who want to access their BLE device from their computer or from outside the BLE's t normal range. This project will become more important once the BLE device software catches up with the new Bluetooth V5 Mesh specification. Then Wifi2BLE will provide internet access to your whole house automation.
