Winc15x0Interface.Scan() Example

SITCore
1

Does anyone have an example of getting this to work? I must be missing something.

I am using SCM20260D Dev board Rev C with a WiFi 7 Click.

I have been able to get the WiFi to connect to an access point and get an IP address. However when I call Winc15x0Interface.Scan();

All I get is an empty array where there should be a list of access points.

I have already called SetCommunicationInterfaceSettings

All of the other functions in Winc15x0Interface appear to work such as getting firmware, MAC address etc.

Does any of this help?

A sample of your non-functioning code is always helpful…

Code that I am using is from that page:

//set pis
var enablePinNumber = SC20260.GpioPin.PI5;
var chipSelectPinNumber = SC20260.GpioPin.PC13;
var irqPinNumber = SC20260.GpioPin.PJ13;
var resetPinNumber = SC20260.GpioPin.PI11;
var spiControllerName = SC20260.SpiBus.Spi3;
var gpioControllerName = SC20260.GpioPin.Id;

//enable
var enablePin = GpioController.GetDefault().OpenPin(enablePinNumber);
enablePin.SetDriveMode(GpioPinDriveMode.Output);
enablePin.Write(GpioPinValue.High);

SpiNetworkCommunicationInterfaceSettings netInterfaceSettings =
    new SpiNetworkCommunicationInterfaceSettings();

var chipselect = GpioController.GetDefault().OpenPin(chipSelectPinNumber);

var settings = new SpiConnectionSettings()
{
    ChipSelectLine = chipselect,
    ClockFrequency = 4000000,
    Mode = SpiMode.Mode0,
    ChipSelectType = SpiChipSelectType.Gpio,
    ChipSelectHoldTime = TimeSpan.FromTicks(10),
    ChipSelectSetupTime = TimeSpan.FromTicks(10)
};

// netInterfaceSettings
netInterfaceSettings.SpiApiName = spiControllerName;
netInterfaceSettings.SpiSettings = settings;

netInterfaceSettings.GpioApiName = gpioControllerName;

netInterfaceSettings.InterruptPin = GpioController.GetDefault().OpenPin(irqPinNumber);
netInterfaceSettings.InterruptEdge = GpioPinEdge.FallingEdge;
netInterfaceSettings.InterruptDriveMode = GpioPinDriveMode.InputPullUp;

netInterfaceSettings.ResetPin = GpioController.GetDefault().OpenPin(resetPinNumber);
netInterfaceSettings.ResetActiveState = GpioPinValue.Low;

var networkController = NetworkController.FromName(SC20260.NetworkController.ATWinc15x0);

networkController.SetCommunicationInterfaceSettings(netInterfaceSettings);
networkController.SetAsDefaultController();


//Scan for WiFi access points:
string[] ssidList = Winc15x0Interface.Scan();

Debug.WriteLine("Networks Found: " + ssidList.Length);

foreach (String str in ssidList)
{
    Debug.Write(str);
}


Thread.Sleep(5000);

I just get Networks Found: 0
