ESP32 Forum

Hi,
I need general guidelines whether this thing is possible and if so how:
I want to create an iPhone/Android app that will receives image frames from ESP32S3 Sense(and then turns them into a video).
Is it possible to just send it through BLE or will it be too slow?
If yes, which format is most recommended?
Thanks

How many images per second do you want? At what resolution?
BLE in theory does 1Mbit/s (up to 2Mbit/s in BLE5), but due to protocol overhead 50-70% of that is a more realistic maximum usable bandwidth. At 10 FPS that'd leave you with about 50-100Kbit (~6-12KB) for each frame... OTOH, at 0.1 FPS you could get decent timelapses over that link.
