B4R Question serial communication between DUE and Uno and Android

[newbie]

I have the following Hardware configuration:

Android DUE UNO
<-- Bluetooth/Ser1 -->
<-- Ser2 / (10/11) -->

Communication between Android and DUe in both directions OK
Receiving Data from UNO, OK

Only sending Data from DUe to UNO not works !
The Data was send , but on the UNO the newdata-event was not fired.

DUE-Code:

Private Sub AppStart
   RunNative("SerialNative1", Null)
   Stream1.Initialize(SerialNative1, "Android_NewData", Null)
   
   RunNative("SerialNative2", Null)
   Stream2.Initialize(SerialNative2, "Slave_NewData", Null)
...

Sub Timer1_Tick
   Log("timer")
   Stream2.Write(ser.ConvertArrayToBytes(Array("BOT",201,1,"EOT")))
...

UNO-Code:

Private Sub AppStart
  Serial1.Initialize(115200)
  Log("appstart")
   
   'softserial.Initialize(9600,SerPin.A0,SerPin.A1)
   softserial.Initialize(9600,10,11)
   astream.Initialize(softserial.Stream, "astream_newdata", Null)
...

Sub astream_newdata (Buffer() As Byte)
  Dim be(20) As Object
  Dim data() As Object = ser.ConvertBytesToArray(Buffer,be)
   
   Log("Received:------------------------")
  For Each o As Object In data
     Log(o)
  Next
 .....

Has anybody some suggestions ?

What is the inline C? If you used this code as an example then the baud rate is different for SerialNative2. Are you sure you have the correct pins connected? Serial2 on pins 17 (RX) and 16 (TX) for the DUE, so uno-due -> 10-16, 11-17. Try the error events. What is the #StackBufferSize?

 

[Erel]

You should initialize AsyncStreams in prefix mode (in both sides).

Inline C, cabels,pins baudrate,level-shifter are o, stackbuffersize are standard 300

it is not possible to use prefixmode with a DUE !!!

compiling gives this error

Please post an example that doesn't compile !!!

I've tested it with this code and it compiles properly:

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
End Sub

Private Sub AppStart
   Serial1.Initialize(115200)
   Log("AppStart")
   Dim astream As AsyncStreams
   astream.InitializePrefix(Serial1.Stream, False, "astream_NewData", "astream_Error")
End Sub

Sub AStream_Error
   
End Sub

Sub AStream_NewData (Buffer() As Byte)
   
End Sub

End Sub

Sub AStream_Error
  
End Sub

Sub AStream_NewData (Buffer() As Byte)
  
End Sub

Sorry, i see my sub Astream_Error was wrong declared (compiling is now ok)

Now i have changed the Due and UNO-side to astream.InitializePrefix
but the Problem is the same , the receiving-event on the uno was not fired, also the error-event
also try :
-other serial on the Due
-other Ports on the UNO
- increasing the stackbuffer size
all the same no receiving data at the UNO

Can you upload the two projects?

Can you upload the two projects?

Here is the code

The Due is a 3.3v board while the Uno is a 5v board. I'm not sure that it is a good idea to connect them directly you can damage the Due board.

Try your solution with two boards using the same voltage and see whether it works.

I am using a level-shifter for the communication ! Where is the problem ?
