0:fc70c47eecb4 | 23 | * \brief An example TLS Client application |
Janos Follath |
0:fc70c47eecb4 | 24 | * This application sends an HTTPS request to developer.mbed.org and searches for a string in |
Janos Follath |
0:fc70c47eecb4 | 25 | * the result. |
Janos Follath |
0:fc70c47eecb4 | 26 | * |
Janos Follath |
0:fc70c47eecb4 | 27 | * This example is implemented as a logic class (HelloHTTPS) wrapping a TCP socket. |
Janos Follath |
0:fc70c47eecb4 | 28 | * The logic class handles all events, leaving the main loop to just check if the process |
Janos Follath |
0:fc70c47eecb4 | 29 | * has finished. |
