    This library makes it very simple to advertise data through BLE. You just need to call ble.Advertise with the string that you want to advertise as the device name.

    Note that it doesn't support making connections.

    Usage example:

    #StackBufferSize: 600
    Sub Process_Globals
    Public Serial1 As Serial
    Private ble As ESP32SimpleBLE
    Private timer1 As Timer
    End Sub

    Private Sub AppStart
       timer1.Enabled = 
    End Sub

    Private Sub Timer1_Tick
    Dim data As String = JoinStrings(Array As String("B4RTime: "NumberFormat(Millis, 00)))
    If ble.Advertise(data) = False Then
    Log("failed to set name.")
    End If
    End Sub
    iOS app:

    The clients need to scan for near by devices and check the device name.
    B4i and B4A clients examples are attached.

    On Android the name is cached so we need to get it from the advertising data map.
    On iOS it stops scanning after a while so we restart the scanning process every 10 seconds.
