Anyone can help me find out my error ? When I sent data from Arduino to app inventor via blutooth (Serial.print("...");   )  and save to labe  it display not correctly. I have try many time but not success !

The file "1.jpg " is correct and from 2-8 is wrong data

I attack aia file if necessary 

This is block cause an errror

how do you want to display your data?

probably you better use println instead of print?

see also https://groups.google.com/forum/#!searchin/mitappinventortest/Arduino$20println

and don't hesitate to do a search in the forum, there are plenty of Arduino and bluetooth examples around...

I want to sent muti sensor value from arduino to android via blutooth and  seperate data each value from arduino to each label in app inventor by ";" charactor.

Now I sent muti sensor value to 1 label without seperate It also make an error

I also use println("value") but no effect

sorry, I do not understand the issue, you might want to elaborate

in case there is an error, it probably would help to tell us what kind of error you get...

probably @ABG has an idea?

I see 4 values in your incoming message, separated by commas (,) that you want to put into 4 labels,

and you want to send all 4 values together and receive them together?

You have the proper delimiter value of 10 in your screen1 btclient, but you did not request a full message, only what was available.

See attached for how to do it.

Be sure you use print() for values 1,2,3 but println() for value 4 to terminate message only at the end.

By the way, screen2 can not share a bt connection with screen1.

Reviewing my post, I notice that you don't split up the incoming message in the timer block.

Wouldn't that be the logical place to split it up for the other 4 labels,

immediately after it has changed?

As I said, I had this error even when I didn't seperate to each label.

I used 1 label to recive muti data sensor it also make an error.

If I seperate, 4 label will also have error as 1 label. So I start my problem at 1 label to easy to see

Ps: I will try to fix as you say in arduino and block you sent me. Hoping that it will work

I want to sent my muti sensor value from my arduino to app inventor in muti label.
But even when i use 1 label to recive muti sensor. It still arrange not correctly. So I start my problem at 1 label to easy exchage
You can compare each pictures I upload at circle I mark for detail

It seem to be successful, thank you so much for helping me. I hope I will be studing more from you - Abraham Getzler and Taifun7

Hi Huong,

Your app looks great. May I ask if you are in Vietnam so that we could collaborate regarding App Inventor.
