Ayabonga Member Jun 20, 2020 #1 Hello guys, I want to send a command to my MCU along with its data but i want to split the data because its from 3 different/separate textboxes but currently its writing everything in one line. Instead of writing 789 to MCU i want to seperate it three values like: 7 8 9 Please also check the screenshot of MCU B4X: [CODE=b4x]Sub btn_Execute_Click If connected Then Hennyval = Hennytxt.Text Sodaval = Sodatxt.Text Remmyval = Remytxt.Text TextWriter1.WriteLine("!Execute " & Remmyval & Hennyval & Sodaval & "#" ) 'send the command protocol to the Microcontroller through serial port. TextWriter1.Flush 'clear the serialport TX buffer to make sure the previous string gets sent. I tried this but need to press the button 3 times and I want to press it once. 'TextWriter1.WriteLine("!Henny #") 'TextWriter1.WriteLine("!Execute " & Remmyval & "#" ) 'TextWriter1.WriteLine("!Execute " & Hennyval & "#" ) 'TextWriter1.WriteLine("!Execute " & Sodaval & "#" ) End If [/CODE] code.

Search Results www.b4x.com Click to expand... Thank you. I added the AsyncSteamsText module but i am not sure how to use it. I want to send text from the app to my MCU (NUCLEO-F446RE) using HC-06 bluetooth module. It works but the problem i have it put all these texts(numbers) from 3 textboxes into 1 line. How can I separate these texts? Upvote 0
