GPS Mobile APP
GPS Smartphone APP
For the APP we are going to use the Blynk APP again. The app is very simple and requires just a few drag and drop placements and settings to setup. If you are new to the Blynk App see this tutorial on setting up the NODEMCU and Blynk App.
If you don't already have the Blynk APP on your smartphone from the Mower project download this now and set it up.
Combining the APP with Mower App
Create a new tab in the existing Mower APP and label this tab "GPS" and the original screen which also now has a tab "Mower".
Go to the Blynk APP setup icon (nut icon) and go to devices. Add a device and select the ESP32 board. This will send a new Auth Key to your email address. Enter this Blynk Auth Key into the ESP32 Arduino Code.
This will add the ESP32 board to the APP
Important!!- ensure the source for each new GPS element used is the ESP32 board.
Building the APP
Fill the APP with the following elements and change the setting of each element as described in the table below. If you don't have enough credits to build the elements then you will need to purchase these in the Blynk App. (not expensive just a few euros).
|Element||Pin Type||Pin Number||Title|
|Value Display||Virtual||2||Mower Satellites|
|Value Display||Virtual||3||Mower Lattitude|
|Value Display||Virtual||5||Mower In(1) Out(0)|
|Value Display||Virtual||4||Mower Longitude|
The APP consists of just 5 elements. 1 GPS Map and 4 Value displays. The position and size of the elements can be changed by long pressing the element and then dragging the element around the screen.
