Hi,

i didn’t try it with the classic Bluetooth connection.
If you have a library which only gets the file as parameter and does everything else (classic Bluetooth or BLE - depending in file size) you can share it here :)


Hello! Did you already solve it? Can you share your´e code and app you are ...

Thanks for your replay chegewara :)

1) file size about 2.8 MB
2) 2.8 MB within 30-60 sec - the faster the better
3) for the app I'm using Ionic with the plugin (cordova-plugin-ble-central and @ionic-native/ble)

Is this filesize and transfer speed possible?
Which methodology and process can I use ...

I am currently building a project with following vision:
- buffers motion data on the ESP32 in a file -> send this data after a while (once per hour) to an app (iOS/Android)
-> working approach:
--> App connect to ESP32 via BLE -> WORKING
--> App sends data to ESP (trigger for ESP to send saved ...
