Want to decide which framework is better choice for image transfer on wireless network

Postby ujurmsde » Wed Nov 30, 2022 5:15 pm

I want to create a project where I need to decide which is a better choice for me to transfer images from different esp-eyes to one esp which is at central location.

I have seen that there is esp-wifi-mesh, esp-ble-mesh and also there is bluetooth classic. I am confused which will serve batter for my case. Is there any comparison between these libraries?

Range?
Not more than 10 meters.

But not sure how much the bandwidth Bluetooth can provide to transfer the image. Also not sure is about weather both Bluetooth and wifi can co-exist? if so when? one more open question is about how much power consumption will this have? Can it be battery powered? etc etc...

From what I know, bluetooth and wifi can coexist on ESP32. You want to use BLE mesh only for small "trigger"-like inputs not for transfering huge data. Usually only data of two bytes is sent. It's really made for battery powered low energy devices.

ESP-WIFI mesh is better but we're also evaluation if we can use it to send big ~2MB OTA binaries with it.
