connect to bonded device using Masteremulator C#

Kuhn

Hi all,

I am using a C# application with the masteremulator dll to connect to a nRF51822 with S110 V8.0.0

I can bond with a new device, and communicate with it in a secure way. But I don't know how to reconnect later with this bonded device.

I did not find useful info in the examples.

How can the c# application know whether or not the bond() function has to be called?

Any information or example is welcome.

I use function RestoreBondInformation and GetBondInformation to save and restore the bonding information.

    I was having the same issue and go it working in the OnConnected event with the following code, although I have to reseat the dongle some of the time to get it to work.

          Task.Run(() =>
        {
        try
        {
            SecurityParameters securityParams = new SecurityParameters();     
            masterEmulator.DeleteBondInformation();
            isBonded = masterEmulator.Bond(securityParams);
            if (isBonded)
            {
                s = masterEmulator.GetBondInformation();
                if (File.Exists(@"C:\temp\bond.txt"))
                {
                    File.Delete(@"C:\temp\bond.txt");
                }
                File.WriteAllText(@"C:\temp\bond.txt", s);
            }
            else
            {
                if (File.Exists(@"C:\temp\bond.txt"))
                {
                    masterEmulator.DeleteBondInformation();
                    masterEmulator.RestoreBondInformation(File.ReadAllText(@"C:\temp\bond.txt"));
                    masterEmulator.RefreshKeys();
                }
            }
            
            DiscoverPipes();
            OpenRemotePipes();
        }
        catch (Exception ex)
        {
            LogErrorMessage(string.Format("Exception in OnConnected: {0}", ex.Message),ex.StackTrace);
        }
        });
