ESP32 Forum

Hello everyone, I have some ESP32 working in MESH with a firmware based in the release/v0.5 branch of ESP-MDF avaible in github
https://github.com/espressif/esp-mdf/tree/release/v0.5

Now I am trying to connect them with another module which have its firmware based in the new master branch (after refactoring) avaible in github repo, but when I configure de device, even if I use the same MESH ID it connects directly to the router ignoring the existing meshh network.

My question is:

Is there a way I can connect devices using the new versión of ESP-MDF to the ones which are using the old version?


Thanks for your help

Hi pardmx,

There is an update from IDF v3.1 to v3.2, that if IE encryption is enabled the v3.1 devices and v3.2 devices can't coexist in a same mesh network. We are working on this to find a solution. It will be good if you can update your old version devices to the v3.2.

Thanks for the reply I will try to update my devices, the problem is that I have about 2000 with v3.1 everyone have OTA enable.
If I do the update sending the app.bin compiled with v3.2 through OTA what issues I could have? because the partition table is different from one version to another.

Thanks

Hi pardmx,

There should be no problem. You can try with small amount of devices first before upgrading all the devices. Please let us know if any issue occurs.
