If you have a very tiny image, then yes you could get it in an extended advertising packet (up to 254 bytes). But in practice, I doubt that would be much to look at. You can read more about advertising here.

Hi again,

First of all, thank you for your quick response. I was considering using Long Range (Coded PHY) but I think that it's still problematic because of not being able to retransmit. Is there a way that fit the image into one chunk and use this chunk to broadcast?

Thank you in advance

Hi,

(Almost) everything is possible. However, you will get much lower throughput with advertising, and also, you will not get any retransmissions. That means that the receiver may not get the whole image file. You will get better throughput if you use extended advertising with longer packets on the secondary channels. That will not be compatible with older devices, though.
