does not work because the SendMessage command does not send bytes that are not valid characters, such as '$00', '$0A'.

[Handoko]

Not I didn't mean like that.

You convert a char $0A to become a string that contains 2 characters '0A'.

This trick is useful for transmitting binary data as human-readable text, read more:

[abssistemas]

I understood, but then I would have to convert inside my firmware again, I did not want that.
The bluetoothclientsocket.pas file sends text and bytes, with the WriteMessage and write method respectively. Would you be able to implement the write method in the tcpsocketclient.pas file?

[Handoko]

It doesn't seem hard to implement but unfortunately I'm not familiar with network programming.

You can make a feature request. But if you need the feature to be implemented quickly, you can consider to create a bounty for it:

Okay, thanks for the help.

Hi abssistemas!

Can you try  "procedure SendFile(fullPath: string) ...?

I'm using the jTCPSocketClient component in an android project and need to send a 1024 bytes sequence, but it can not send bytes, only string by the jTCPSocketClient.SendMessage command.
It would have a way to send bytes instead of text.

Done! 

Code: Pascal  [Select][+][-]

1. procedure TAndroidModule1.jButton2Click(Sender: TObject);
2. var
3.   data: TDynArrayOfJByte;
4. begin
5.   SetLength(data, 2);
6.   data[0]:= $0A;
7.   data[1]:= $00;
8.  
9.   if  FConnected then
10.       jTCPSocketClient1.SendBytes(data, True);
11.  
12.            //"True" will write FIRST the Len=2 to the Server ...
13.            //"False" will write only the "data" to the Server ...
14.  
15.    SetLength(data, 0);
16. end;  
17.

I'm using version 0.7.0, how do I upgrade to 0.8.0, so I can test? I tried updating online but did not upgrade.

Well,  the "ideal" is to install a "git" client,
so you can "update/synchronize"  your system...

But,  You can, too,  "download" as zip e reinstall/replace all packages/folders..

   .Install order.

Hi,  CC!

1) For not "AppCompat" themes  you can use/target any recent API .... [warning: the R24.4.1 is the last that support "ant" builder]   ... Recommended: target 21 or 22 [not run permission is required !!!]

2) Yes, R24.4.1  [or any...] is not "complete" out of box...

[from "LAMW getting started.txt"]
                1)after unpacked [R24.4.1 or any...], open a terminal and go to "sdk/tools"  folder
      2)run  cmd "android sdk" to open a GUI "SDK Manager"
      3)check "Android SDK Tools"
      4)check "Android SDK Platform-Tools"
      
      5)check "Android SDK Build-Tools 25.0.3" [need for "gradle" builder]    

      5.1)check  "Android SDK Build-Tools 26.0.2"  [need for "gradle" builder]
      
      6)go to "Android 7.1.1 (API 25)" and check  "SDK Platform" [need for "AppCompat" themes and "gradle" builder]

      7)go to "Extras" and check:
            "Android Support Repository"            
            "Android Support Library"            
            "Google USB Drive"
 
3) For "AppCompat" themes the only "recommended"  for LAMW:

"Android SDK Build-Tools 25.0.3" [need by old "gradle" plugin]    
"Android SDK Build-Tools 26.0.2"  [need by 3.0.1  "gradle" plugin ...]
"Android 7.1.1 (API 25)"
"Extras":          "Android Support Repository"            
            "Android Support Library"

Thanks!

I compiled tfpandroidbridge_pack.lpk and it worked, but when I tried to compile the lazandroidwizardpack.lpk it gave error as follows:

@abssistemas

Before you try (re)instal any package you need open a default windows project in Lazarus....

[if a LAMW project is open in the IDE...  you can get some strange error!!!]

[abssistemas]

Okay, now it worked.
I have another problem now. When I send an array of 1024 bytes using the method, jTCPSocketClient1.SendBytes (data, False); it works normally, but soon after sending the bytes the connection is lost, and I do not get any more data through the socket. I have to connect again. The jTCPSocketClient1.SendMessage method remains connected without problems.

[jmpessoa]

@abssistemas

OK. I will improve  "jTCPSocketClient"  SendBytes!

Thank you!
