WeвЂ™ll then learn how to compile the code we write and download it to the NXT. In this case weвЂ™ll be using RobotC as our IDE.

Additionally, you will learn debugging techniques and how to use the built in debugger.Д®xplanation of the Integrated Development Environment (IDE) and its parts Top Menubar Side Functions Panel Code Window Error Window Compile/Download code to the NXT Run the code SECTION 1 WeвЂ™ll start buy learning about the software that we use to write our programs, also called an Integrated Development Environment, or an IDE. You will also be introduced to techniques for configuring and interfacing sensors.

RobotC Specifics (next lecture) You will learn to harness the full power of RobotC by using its variety of preprogrammed functions and directives. Introduction to Programming Concepts RobotC Specifics (next lecture) OVERVIEW Basic Introduction to the Programming Software You will become familiar with the programming environment and learn a few basic skills like compiling/running codes and digging for help Introduction to Programming Concepts You will learn basic concepts of C programming language like syntax, control structures, etc. Run the programs as per the instructions for the samples above, and observe the results on the NXT screen.2 OVERVIEW Overview Basic Introduction to the Programming Software These are essentially the same programs as above, except these will allow you to send through 3 values where the above programs would send only one value at the time. Checking for a message every half a second is

NxtDisplayBigTextLine(2,'1: %d',my_message) Display the value as stored in the variable LetвЂ™s say something got through if the signal is not zero LetвЂ™s wait a bit and send something else Then move on to the slightly more useful programs below. If you do that, you can nicely repeat the procedure and wait for a message to come in. After storing this value in a variable for further usage, use ClearMessage() to set the values back to 0 (erase your email inbox). So, if you find something that is not 0, thatвЂ™s the value that was sent by the other NXT. If thereвЂ™s no message, youвЂ™ll find 0 as the message. The only issue here is that this mailbox will hold only one email, so old messages are overwritten when new ones come in. You wonвЂ™t miss it, it will be in the mail box. So, thereвЂ™s no need to check every milisecond of the day. But like email, messages are stored for your review until you open them. YouвЂ™ll never know youвЂ™ve got a new email unless you check. Think of it as emails you get from a friend. The key is that you have to keep looking for messages on the receiver part. IвЂ™ve added some comments to the code to help you understand what each portion of the code does. When you do this, the number 23 shows up on the receiving NXT.

Transfer SenderSimple.c to your other NXT.

Use USB for this! (Bluetooth will be in use between your NXTвЂ™s.)

Robotc code examples Bluetooth#

I assume that your NXTвЂ™s are connected via Bluetooth (see вЂњset upвЂќ section). The next examples (SenderSimple.c and ReceiverSimple.c) demonstrate the functionality to send one value from one NXT to another. In some occasions you want to send some basic numbers from one NXT to the other.

The symbol in the top left of the screen indicates that your NXTвЂ™s are connected.

Choose the NXT that you want to connect to.

(Only the first time) Go to Bluetooth > Search.

Connect the NXTвЂ™s using the menu on the NXT brick:.

You can just copy paste the code from below, or download all 4 sample programs.

Newer versions may have issues with this code.

This code was tested with RobotC 3.08.

(You can use bluetooth with NXT-G, too, but thatвЂ™s not discussed here). This page will show you two sets of programs that demonstrate the most basic Bluetooth example programs for two NXT with RobotC. ThatвЂ™s apparently a bit tricky, but itвЂ™s really not difficult if youвЂ™ve got a simple place to start. Bluetooth is a cool feature and itвЂ™s especially fun if you can make it work.
