The app adds a SensorVisualizationScenario class that manages and initializes sensors and creates DX rendering models for the app. The application is built starting from a DX11 template app. It shows visualizations of frames from the two front head tracking cameras, depth and AB frames from the depth camera and a visualization of IMU accelerations visualized as lengths of a 3d coordinate system. Run the programs as per the instructions for the samples above, and observe the results on the NXT screen.This sample is a Holographic UWP application that demonstrates visualizing sensor streams live on the device. 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 SAMPLE CODE 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.
