Re: OTA of factory app

For future users who find this: changing factory app thru OTA should be doable.
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

Re: ESP32 Unable to get IP from Server in Native_OTA

I recently faced very similar problem and it was caused by our DHCP service not providing IP to some MACs or something like that. Recommend you try same code but connecting to a different wifi network just to check that it is now caused by that wifi network, for example I checked this using wifi hot...

Re: SYSTEM_EVENT_STA_GOT_IP never received, other units work, Wrover-B defective?

We found out the problem!!! After some investigation we found out our DHCP server in my company was working erratically, not giving IP to some specific MAC addresses, but working ok with the vast majority. No idea why. We have Windows Server 2012, we removed the option of DHCP redundancy and restart...

Added some debug logs to github issue, still no idea of why just one of my 4 units is not getting the IP event but seems to be connecting OK to wifi.

Re: Performance benchmark compared to Cortex M4 series

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...
