Bug? No Log output

[JanG]

After some month the log output on the ide doesn't work:

1. Developing a sketch with arduino IDE 1.8.5
=> Log on Serial monitor works as expected.

2. Developing on b4r, no log output on b4r ide.
=> The log output on the arduino IDE serial monitor does work.

Any ideas?

Double check your board rates and the board settings in B4R...

 

[JanG]

I did! This doesn't seem to be the problem. b4r sketch on b4r ide: no logs. Same sketch, same rates: on arduino IDE serial monitor: everything fine.

Are you sure that Arduino IDE is not locking the port? Try to restart the computer and test it.

 

[JanG]

Yes.

New test:
1. Fresh restarted windows.
2. Only B4R started (no arduino IDE).
3. Using this program for testing log:

#Region Project Attributes
    #AutoFlushLogs: True
    #CheckArrayBounds: True
    #StackBufferSize: 300
#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
End Sub

Private Sub AppStart
    Serial1.Initialize(115200)
    Delay(1000)
    Log("AppStart")
End Sub

4. Output of b4r:

5. Disconnecting b4r, connecting Arduino IDE serial monitor. Reseting ESP8266, output:

My configuration:
- Windows 8.1 64 Bit
- Arduino IDE 1.8.5
- B4R 2.20
- Board Setup:

On my Laptop I have the same problem (months ago). But with the same configuration on my "normal" computer I didn't have this problems. "Same configuration" is not true, maybe it was b4r 1.8.

New ideas?

Try the external serial connector: https://www.b4x.com/android/forum/threads/tool-external-serial-connector.65724/#content

 

[JanG]

Doesn't work, too. b4r connects to Serial Connector. When resetting the ESP8266 I see the bad characters in the connector. But I don't see "AppStarted"... Very annoying
a) Serial monitor:

b) Arduino IDE:

Why? What can I do?

 

[JanG]

I tried the small terminal programm "Termite". It shows the data "AppStart". So it must be a problem of b4r or one of its components. The interesting thing is that the b4j-App "serial connector" doesn't work, too. So what kind of shared component do this two applications use that others (like arduino ide, termite) do not use?

 

[Erel]

Both are based on the same Java library (jssc). I'm not sure why it doesn't work for you.

Reinstalling the driver might help.

 

[JanG]

I reinstalled java. I reinstalled the arduino IDE. I reinstalled the driver. No success...

I don't know what to do now. b4r quite unusable...

 

[Erel]

You can use an external logger though it will require starting and stopping it each time.

 

[JanG]

Yes, that's my workaround. But it kills the great usability of the b4r ide. No better solution?

 

[Erel]

I'm afraid no. You can test it on a different computer or test it with this computer and a different board.

Many developers use B4R with ESP8266 and it usually works properly.

 

[JanG]

I think I isolated the problem:
It's not an issue with the specific device. It's because I wired Pin RX. When I diswire this Pin the logging in b4x works. So I ask if you can change your internal code that a wired RX (or TX) is not a problem. In my opinion it is possible beacuse for other tools a wired RX is not a problem (as shown).
