vb and prop question using eb500

russ christensen

Hi everybody, yet again. Since today is the day I'm devoting solely to working on my robot, i have another question. I'm having issues passing data from the prop to my vb program. Just testing i'm sending a string through the bluetooth every 100 milliseconds. the first one shows up in my text box immediately, a moment later about 15 more show up, then i don't get anymore for a while. however they do keep coming. I need the data to show up right when i get it, does anybody know how to print the buffer immediately?

Hi Russ, it depends on your version of Visual Basic. I know that if you are using Visual Studio·2005/2008 you would capture data coming to the PC with the Data Received event handler and then pass it on to the text box using a delegate.

Thats exactly what i'm doing, but there's still a delay. Here's some code if anybody cares to take a gander. it is using vb2008 and steve norris's eb500.spin which is also attached

edit: most of the code i adapted from this tutorial.

Hi, DevX is a good resource. I don't have the time right now to look at your source perhaps someone else can help with that. I did have time to jot an example down onto Notepad , insert it into your existing code and see if it makes any difference.

Note it uses a RichTextBox not a TextBox , alter that if you need to.

EDIT: error, switch the two lines that receive byte values or ASCII I labelled them wrongly.

One more question. since the send line and receive line are different, can i have one cog listening and one cog sending at the same time, without conflict?
