I write a small project to test B4R (WiFiSocket client) send byte array to B4J (ServerSocket Server). Server side can received the byte array but B4R after send the array byte get error and restart.
error code:
B4X:
load 0x4010f000, len 3584, room 16
tail 0
chksum 0xb0
csum 0xb0

AppStart
ConnectToNetwork Local IP: 192.168.0.110

    server.Listen
End Sub

B4R Client code:
B4X:

    #CheckArrayBounds: True
    #StackBufferSize: 600
#End Region

Sub Process_Globals
    'These global variables will be declared once when the application starts.
    'Public variables can be accessed from all modules.
    Public Serial1 As Serial
    Private astream As AsyncStreams
    Public WiFi As ESP8266WiFi
    Private bc As ByteConverter
End Sub

Private Sub AppStart
    Serial1.Initialize(115200)
    Log("AppStart")
    ConnectToNetwork
End Sub


Sub Connect
    Dim sock As WiFiSocket
    sock.ConnectIP(Array As Byte(192, 168, 0, 83), 17178)
    If sock.Connected Then
        astream.InitializePrefix(sock.Stream,False, "astream_NewData", "astream_Error")
        astream.Write(bc.StringToBytes("ABCDEFG"))
    End If
    sock.Close
End Sub

Sub astream_Error
    Log("Error")
End Sub

Sub astream_NewData (Buffer() As Byte)
    
End Sub

Public Sub ConnectToNetwork
    WiFi.Disconnect
    If WiFi.Connect2("xxxx", "xxx") Then
        Log("ConnectToNetwork Local IP: ", WiFi.LocalIp)
        Connect
    Else
        Log("ConnectToNetwork Failed to connect.")
    End If
End Sub

and I upload small project, who can help me test, is it same errors.
