Displays an interactive map with either street or satellite overlays, with the latest position of the hardware and optionally the app shown. The position of the device running the app is shown if the Show my location widget option is enabled.
Select or create a datastream of location or string.
The widget controls consist of gestures:
Home: Click on the arrow at the bottom right of the map to zoom to the latest position.
Zoom: pinch open to zoom out, pinch closed to zoom in.
Set North up: when the map is rotated, a compass icon will be in the upper right of the map. Tap this icon to set the orientation of the map so the North direction is up.
Double tap: zooms the map in.
Drag: pans the map.
When button is pressed, value is sent and stored into the Blynk.Cloud. After that it's sent to your device.
For example, if Widget is set to Datastream with Virtual Pin V7, you can use such code:
Hardware:
HTTP API:
You can change certain properties of the Widget from your hardware. For that, use this command:
Where:
vPin is: virtual pin number the widget is assigned to
widgetProperty: property you want to change
propertyValue: value of the property you want to change
Don't put Blynk.setProperty()into the void loop() as it can cause a flood of messages and your hardware will be disconnected. Send such updates only when necessary, or use timers.
Widget will be greyed out on UI and users won't be able to tap on it.
Widget will be hidden from dashboard. Design your UI so that it doesn't look weird when there is no widget.
GET https://{server_address}/external/api/update/property?token={your 32 char token}&pin={your vPin}&{property}={value}
The endpoint allows you to update the Datastream Property value via GET request. All widgets (both web and mobile) that are assigned to this datastream will inherit this property. The Datastream Property is persistent and will be stored forever until you change it with another value. In order to clear the property you need to clear the device data in device actions menu.
Example:
https://blynk.cloud/external/api/update/property?token=GVki9IC70vb3IqvsV0YD3el4y0OpneL1&pin=V2&label=My%20Label
https://blynk.cloud/external/api/update/property?token=GVki9IC70vb3IqvsV0YD3el4y0OpneL1&pin=V1&color=%23D3435C
https://blynk.cloud/external/api/update/property?token=GVki9IC70vb3IqvsV0YD3el4y0OpneL1&pin=V1&isDisabled=true
Don't put Blynk.virtualWrite()into the void loop() as it can cause a flood of messages and your hardware will be disconnected. Send such updates only when necessary, use flags, or .
Sketch:
You can change the properties label, color, isDisabled, isHidden of the widget from your hardware, or via an . The URL must be encoded, so spaces in labels must be replaced with %20, and color hexadecimal values in the HTTP API URL must include the hash # character urlencoded as %23.
You can update your hardware to the latest datastream value from Blynk.Cloud after your hardware went offline, and then came online again. Use Blynk.syncVirtual() to update a single virtual pin, or Blynk.syncAll() to update all virtual pins. See for more details.
