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, that’s the value that was sent by the other NXT.
If there’s no message, you’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 won’t miss it, it will be in the mail box. So, there’s no need to check every milisecond of the day. But like email, messages are stored for your review until you open them. You’ll never know you’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.

I’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.

I assume that your NXT’s are connected via Bluetooth (see “set up” 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 NXT’s are connected.Choose the NXT that you want to connect to.(Only the first time) Go to Bluetooth > Search.Connect the NXT’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 that’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. That’s apparently a bit tricky, but it’s really not difficult if you’ve got a simple place to start. Bluetooth is a cool feature and it’s especially fun if you can make it work.
