Hi, How can i send an image from mobile phone to ESP32 via BLE ?
Why do you want to do that, when just about any other method of transmission is faster, more reliable and easier to implement?
You need to provide a LOT more information. Next, read the pinned post re 'How to get the most from the forum'. I will tell you in advance that you need to attempt to do this yourself, then, when it doesn't work, post all your code in code tags, post any error logs in code tags and a picture of the hand-drawn wiring as well. Good luck.
