Member Function Documentation
| bool connect | ( | unsigned long | timeout = BLYNK_TIMEOUT_MS *3 ) |
Connects to the server.
Blocks until connected or timeout happens. May take less or more then timeout value.
- Parameters:
-
timeout Connection timeout
- Returns:
- True if connected to the server
| bool connected | ( | ) |
- Returns:
- True if connected to the server
| void delay | ( | unsigned long | ms ) |
Delays for N milliseconds, handling server communication in background.
- Warning:
- Should be used very carefully, especially on platforms with small RAM.
- Parameters:
-
ms Milliseconds to wait
Definition at line 296 of file BlynkApi.h.
| void disconnect | ( | ) |
Disconnects from the server.
It will not try to reconnect, until connect() is called
| void email | ( | const T1 & | subject, |
| const T2 & | msg | ||
| ) |
Sends an email message.
- Parameters:
-
subject Subject of message msg Text of the message
Definition at line 207 of file BlynkApi.h.
| void email | ( | const char * | email, |
| const T1 & | subject, | ||
| const T2 & | msg | ||
| ) |
Sends an email message.
- Parameters:
-
email Email to send to subject Subject of message msg Text of the message
Definition at line 191 of file BlynkApi.h.
| void notify | ( | const T & | msg ) |
Sends a push notification to the App.
- Parameters:
-
msg Text of the message
Definition at line 163 of file BlynkApi.h.
| void refresh | ( | int | pin ) |
Refreshes value of a widget by running user-defined BLYNK_READ handler of a pin.
- Parameters:
-
pin Virtual Pin number
Definition at line 281 of file BlynkApi.h.
| bool run | ( | bool | available = false ) |
Performs Blynk-related housekeeping and processes incoming commands.
- Parameters:
-
available True if there is incoming data to process Only used when user manages connection manually.
| void sendInternal | ( | Args... | params ) |
Sends internal command.
Definition at line 122 of file BlynkApi.h.
| void setProperty | ( | int | pin, |
| const T & | property, | ||
| Args... | values | ||
| ) |
Sets property of a Widget.
- Parameters:
-
pin Virtual Pin number property Property name ("label", "labels", "color", ...) value Property value
Definition at line 225 of file BlynkApi.h.
| void sms | ( | const T & | msg ) |
| void syncAll | ( | ) |
Requests Server to re-send current values for all widgets.
Definition at line 114 of file BlynkApi.h.
| void syncVirtual | ( | Args... | pins ) |
Requests App or Server to re-send current value of a Virtual Pin.
This will probably cause user-defined BLYNK_WRITE handler to be called.
- Parameters:
-
pin Virtual Pin number
Definition at line 136 of file BlynkApi.h.
| void tweet | ( | const T & | msg ) |
| void virtualWrite | ( | int | pin, |
| Args... | values | ||
| ) |

- Parameters:
-
pin Virtual Pin number data Value to be sent
Definition at line 73 of file BlynkApi.h.
| void virtualWrite | ( | int | pin, |
| const BlynkParam & | param | ||
| ) |
Sends BlynkParam to a Virtual Pin.
- Parameters:
-
pin Virtual Pin number param
Definition at line 103 of file BlynkApi.h.
| void virtualWriteBinary | ( | int | pin, |
| const void * | buff, | ||
| size_t | len | ||
| ) |
Sends buffer to a Virtual Pin.
- Parameters:
-
pin Virtual Pin number buff Data buffer len Length of data
Definition at line 89 of file BlynkApi.h.
