The SimpleLink™ Wi-Fi® CC3200 LaunchPad™ development kit is an evaluation development platform for the CC3200 wireless microcontroller (MCU) from Texas Instruments; a single-chip programmable MCU with built-in Wi-Fi connectivity.
Requiremets
Setup
1. Download Energia IDE here and install it on your pc.
This tutorial assumes you have already flashed a program into your CC3200 launchpad before. If you’re not sure about this, we recommend flashing the basic “blink” example to make sure you’re being able to code your device.
2. Open Boards Manager from Tools -> Board menu and install CC3200 platform
3. Go to Tools -> Board and select LaunchPad w/ cc3200 (80MHz).
4. Download our library here.
5. Now, click on File -> Include Library -> Add .ZIP Library
6. Select the .ZIP file of Ubidots CC3200-LAUNCHXL and then "Accept" or "Choose"
7. Close the Energia IDE and open it again.
Hardware Setup
Before compile your board make sure your board’s Jumpers are in the right place. The settings below worked for us, but we strongly advise you to follow Energia’s guides to make sure you’re able to program your board:
Put a wire from “TCK” pin to 2 pin in SOP pins
To make sure you're able to code your device, we recommend you flashing the basic "blink" example before start.
Change default name
The library will create a new Ubidots device named "CC3200", also assigns the same name for the device label. If you desire to assign a different device label, please add to your setup() function the line below:
client.setDeviceLabel("my-new-device")Send values to Ubidots
To send one value to Ubidots, go to Sketch -> Examples -> Ubidots CC3200-LAUNCHXL and select the "UbidotsSaveValuesHttp" example.
Update your WiFi crendentials, assign your Ubidots TOKEN and the variable label where is indicated. Once the parameters are assigned, upload the code. Then, open the Serial monitor to check the results.
NOTE: If no response is seen, try unplugging the board and then plugging it again. Make sure the baud rate of the Serial monitor is set to the same one specified in your code.
// This example sends data to multiple variables to
// Ubidots through HTTP protocol.

Send values with context
The following example is to send one value with context to Ubidots, it will create the variable automatically with the label assign by you into the code.
Add your Ubidots TOKEN where indicated, as well as the WI-FI settings.
// This example sends data and context to a variable to
// Ubidots through TCP protocol.

/* Reserves memory to store context array */
char* context = (char*)malloc(sizeof(char) * 60);

Send values with timestamp
The following example is to send one value with timestamp to Ubidots, it will create the variable automatically with the label assign by you into the code.
Add your Ubidots TOKEN where indicated, as well as the WI-FI settings.
// This example sends data along with timestamp in POSIX ms standard
// to a variable to Ubidots API through HTTP, TCP or UDP protocol. /****************************************

float value1 = analogRead(A0);
unsigned long timestamp_seconds = 1571615253L; // Put here your timestamp in seconds
unsigned int timestamp_milliseconds = 0; // Put here the number of milliseconds to shift your timestamp
ubidots.add("temperature", value1, NULL, timestamp_seconds,timestamp_milliseconds); // Change for your variable name

// Do something if values were sent properly

}
Get value from Ubidots
To get the last value of a variable from Ubidots, go to Sketch -> Examples -> Ubidots CC3200-LAUNCHXL and select the "UbidotsGetValueHttp" example.
Update your WiFi crendentials, assign your Ubidots TOKEN, the device and variable label from where you desire obtain the value.
Upload the code, open the Serial monitor to check the results.
NOTE: If no response is seen, try unplugging the board and then plugging it again. Make sure the baud rate of the Serial monitor is set to the same one specified in your code.
// This example retrieves last value of a variable from the Ubidots API
// using HTTP protocol.
