[i was trying to make a gps map navigation system using arduino according to a forum. The author made a chinese app to download the tiles from bing maps api. ill make it clear on how this map works. So basically, we need to enter to the app,

1> resolution of one tile. The person on the forum has adjusted the resolution of the tile to 128×128 px, as the persons screen has that resolution. So i adjusted my map to 240×240 px for this display https://www.waveshare.com/wiki/1.28inch_LCD_Module

2> the coordinates of the map. The app shows a bing map api of the whole world and we have to draw a polygon in such a way that our desired area should be inside the polygon, so that it can download the tiles of a specific resolution and store it to the SD card so that the arduino could read it out and display the map on the screen

3> pressing the save button on the main window should save the map on the sd card or the place we have entered to the app. NOTE: the app creates a file structure like on the image posted.

The problem now im facing with the app is to download the files. when i try to save the file, it says download error 1 or “n” number of download errors. so to find this out, i had to find the original author of the chinese app and it was a forum. to my understanding some people who commented on 2018 or so had the similar error of failed to download and the author said, the bingmaps api version is outdated for the app i mentioned. so how can i change the api version or can i find the similar app? the website i initially found is this one: https://www.elecfreaks.com/blog/post/arduino-gps-map-navigation-system.html but i cant post the actual chinese website as it leaks our ip address and will have a hard time to sign up. also the app can be found on the below of the website i have founded

on my first and quick glance at the error message, i tried to use WMware and tried to run it on windows 7, 8, 10 on both 32 and 64 bits and gave out same errors. and when i checked the app, not inside the exe of the tile downloader app, i thought it uses sharpmap api and i didnt know what was it. i tried to draw other countries or states and found the same problem
