I explain how we changed partition table in this other topic, using a very similar approach you should be able to change factory app I think: viewtopic.php?f=2&t=11482&p=48589#p48589

For future users who find this: dynamically changing the partition table is doable.

I faced this problem because we wanted to change partition table from FACTORY+OTA to OTA0+OTA1, plus we wanted to expand NVS partition size. We got several devices alr...

I recently faced very similar problem and it was caused by our DHCP service not providing IP to some MACs or something like that.

At my company, Sistel, we are at the final stage of product development using ...

I did a very similar comparison in terms of performance and energy consumption with info and tests gathered from the internet a while ago... can't find my notes on that. If I remember correctly, the "only" good things about Xtensa and ESP32 were the price, the higher clock and dual core, and of cour...
