HTTPSLargeData

The example (located in the Adafruit_WICED_Arduino/examples/TLS folder) uses the AdafruitHTTP helper class and

TLS to connect to a secure server and request a large file, which is then read using callbacks.

It tries to calculate the throughput for the specified file, which can be 10KB, 100KB or 1MB (indicate the file you wish to

use before compiling the sketch).

Setup

Set your AP details using the WLAN_SSID and WLAN_PASS flags, setting them to the values used by you own access

point:

Next change the FILE_ID flag to indicate which file you want to load. Valid options are '0', '1', or '2':

Compile and Flash

You can then compile and flash your sketch to the WICED Feather using the 'Download' arrow icon at the top of the

IDE:

You should see the USB DFU progress as the update advances, and there will be a 'Done Uploading' message in the

top left of the status bar when you are done:

Testing the Sketch

Wait a few seconds for the USB CDC serial interface to enumerate, and then open the Serial Monitor using either the

#define WLAN_SSID "YOUR SSID HERE"

#define WLAN_PASS "YOUR SSID KEY HERE"

#define FILE_ID 1

// S3 server to test large files,

const char * file_arr[] =

{

[0] = "/text_10KB.txt" ,

[1] = "/text_100KB.txt" ,

[2] = "/text_1MB.txt" ,

};
