Receive Bluetooth Data from Arduino to MIT App Inventor
Tell your App what the BT Package delimiter (end of data marker) is: In your App, as per your current Blocks, split the string received into a List. Next, check that there are 8 values in the List - only if there are, populate your labels/textboxes. You cannot call your List 'List' as this is a reserved word.

This component provides the Android device's location, using GPS if available and an alternative method otherwise, such as cellular towers or known wireless networks. LocationSensor is a non-visible component providing location information, including longitude, latitude, altitude (if supported by the device), and address.

The following tutorial will show you how to receive multiple sensor readings from your arduino board into you MIT APP INVENTOR 2 APP. If you are using more than one sensor with your Arduino project you have found that it is necessary to send that data and display it on your app. To do this you will need to send all the sensors data at one time.

Be sure to use println() at the end of each message to send from the sending device, to signal end of message. Only use print() in the middle of a message. Be sure not to println() in the middle of a message, or you will break it into two short messages and mess up the item count after you split the message in AI2.

The App Inventor Project includes a test to ensure Bluetooth is switched on. Depending on your Android version (10+), Location will need to be turned on too (before running the App). Test the App as an APK, it will not work in the Companion. What is going on should be clear from the comments in both documents.
App Inventor 2 Bluetooth Receive Text? Top Answer Update
Hi! I'm new at App building. I found an interesting experiment to read via Bluetooth device some data. The sensor I'm reading the data from is a DHT11 (humidity and temperature sensor) and a light dependent resistor. I have the Arduino code and I also have the "final" App. The app itself doesn't work, so I've decided to do it myself. The "blocks" part and the Arduino code are attached. Can.

The AccelerometerSensor1 is the component that detects phone movement. Find the Accelerometer in the Sensors section of the Palette. The Player1 component is a media player - for our app, when the phone is shaken, it plays an mp3 audio file that is specified as the Source in the properties for the player. Find the Player component in the.

I used Serial.print to send each result and then used Serial.write('>'); as the end marker.. In appinventor designer window set the Delimiter byte for Bluetooth client to 62 (the ASCII value for the > character ).. In the blocks window, use Bluetooth cliant1.Receive text and set number of bytes to -1 . App invented will then read until a delimiter is found.

Add a text box to receive data from connected device. The reception of data is implemented using a timer. Per second, the client checks to see if the data is available. If it is than it reads and display the data. So, for this add Clock sensor component which is also a hidden component. 3. Block Editor:

Hello, I'm making an app for a smartphone using app inventor 2 and I'm using Arduino to send values coming from a Controller Area Network communication bus (from an electric bike) but the problem is that the bike sends values going from 0 to 100 in "byte" format.and for example if the arduino sends "40" app inventor sees it as one byte with 2 bytes in it so it doesn't really work, it keeps.

Be sure to use println () at the end of each message to send from the sending device, to signal end of message. Do not rely on timing for this, which is unreliable. In the AI2 Designer, set the Delimiter attribute of the BlueTooth Client component to 10 to recognize the End of Line character.
