This feature exists virtually in any device that can connect to the Internet, and can be quite a good tool to experiment with, for example how far our devices can be from a gateway (router) to work. In this tutorial we have created a simple Wi-Fi scanner, that has printed all available networks within range of our MKR WiFi 1010 board.

#WIFI SCANNER DEVICE DRIVERS#

We have not installed the drivers for the MKR WiFi 1010.

We have not installed the WiFiNINA library. Fing is our favorite free Wi-Fi app because it provides very useful information for wireless networks but isnt at all hard to use.

If the code is not working, there are some common issues we can troubleshoot: If we tried to connect a computer to this network, it would most likely fail.

When this test was done, the board was only a meter away from the router, so the signal strength is great.īut if we look at the other networks, we can see that the signal goes all the way down to -94 dBm, which is very weak. If we look closer at #1 in the list, we can see that the signal is -38 dBm. After 10 seconds of scanning, the available networks will be listed, along with information about the network. When we open it, we will first see the MAC address of our board printed, followed by the text 'Scanning available networks'.

We can now upload the code that can be found in the snippet below to our MKR WiFi 1010 board.Īfter we have uploaded the code to the board, we will need to open the Serial Monitor. RSSI ( ) - retrieves RSSI (signal strength) of found network (measured in dBm). SSID ( ) - retrieves SSID (network name) of found network. encryptionType ( ) - retrieves encryption type of found network. scanNetworks ( ) - scans for nearby networks. macAddress ( ) - obtains the boards MAC address. Now let's take a look at some of the core functionalities of the sketch that we will use.

#WIFI SCANNER DEVICE INSTALL#

In the editor, navigate to Tools > Board > Board Manager., and install the Arduino SAMD boards (32-bits ARM Cortex M0+) core.ģ. If we are using the offline editor, we need to make sure we have the drivers installed for the MKR WiFi 1010 board. If we are using the Web Editor, it is already installed.Ģ. If we are using the offline editor, we can locate this library in Tools > Manage Libraries. For this tutorial, we will need to install the WiFiNINA library. First we need to make sure we have the dependencies installed. There is no need for extra components in the circuit but the board. This tutorial requires no additional circuit. These responses contains information such as name of the network, signal strength in dBm (decibel milli-watts) and encryption type. The device looking for a network or the client, sends a probe request, while nearby networks send probe responses. A device with a Wi-Fi module such as smart-phones, computers or development boards such as the MKR WiFi 1010, search their surroundings, and get a response from nearby networks. Scanning for Wi-Fi networks is a quite straightforward process. Print additional information about these networks.Print available networks in the Serial Monitor.This is done using the NINA-W102 radio module, and in this tutorial, we will go through some simple steps to get this working! Goals One great feature with the MKR WiFi 1010 is the possibility to scan nearby Wi-Fi networks.
