Hi All, I am trying to send a batch of messages to PC from BB10 through Bluetooth

I use:

write( sppDataThread.getFD( ), msg1.toAscii( ), msg.size( ) );
write( sppDataThread.getFD( ), msg2.toAscii( ), msg.size( ) );
write( sppDataThread.getFD( ), msg3.toAscii( ), msg.size( ) );

I face a strange behaviour when i recieve these messages on PC.

I expect to recieve

msg1

msg2

msg3

but I recieve:

msg1

msg1msg2

msg1msg2msg3

I fixed this issue by using:

write( sppDataThread.getFD( ), msg1.toAscii( ), msg.size( ) );
sppDataThread.wait( 200  )
write( sppDataThread.getFD( ), msg2.toAscii( ), msg.size( ) );
sppDataThread.wait( 200  )
write( sppDataThread.getFD( ), msg3.toAscii( ), msg.size( ) );

But I dont want my thread to sleep . It seems that it is a caching issue. How to send messages immediattely correctly?

I can provide 'any' but not sure it will help you.

What is sppDataThread?

How do you declare msg, msg1, msg2 and msg3?

How do you initialize msg, msg1, msg2 and msg3? 

[hishamBakr]

sppDataThread is a thread used to handle bluetooth connection

QString msg1="msg1";

I am not young so probably that's why I'll ask you to give all of them  as well:

I am sorry I didnt get your point. I answered your questions

the issue is. bluetooth buffer a block then flush it. I want to disable that flush by block and I want it to be flush by line

[BGmot]

I don't think it is 'block' issue.

What bothers me is in every wirte you use different variables to push into the socket but you have the same lengh of msg variable that is why I asked you to provide *all 4 variables declarations/initializations.

msg1.toAscii( ), msg.size( )

[hishamBakr]

No that is not the issue

actually the original code is :a method that is called when user presses on a button

when user clicks the button and waits for 400 millisecond between clicks--> no issue happens

when user clicks the button and waits less than 400 millisecond between clicks--> the issue happens


I just wrote msg1,msg2,msg3 to describe my issue

Could you show the code of all the functions where msg, msg1,msg2,msg3 are involved?
