I would like to record the latitude and longitude data of the android phone on the esp32 via BLE. Do you have any suggestion where to get an example or information.
There’s a block in MIT App Inventor that allows you to use GPS location of your phone. See the following figure:
Then, if you go to the Blocks tab, you can see all the methods available to get longitude and latitude.
More information here: http://explore.appinventor.mit.edu/tutorial-type/gps
Then, you can use the BLE extension to send the location to your ESP32.
Let me know if you need further help.
