Think I found the answer in the docs: Before building the application image for OTA updating of an already encrypted device, enable the option Enable flash encryption on boot in project configuration menu. This means that I have to activate the option ‘Flash encryption on boot’, even if it is not ne...

Hi, I want to know if my process for encryption is correct and if it is needed to enable flash encryption in sdkconfig to have OTA updates encrypted. For now my process is the following: esptool.py --port $SERIAL_PORT erase_flash espsecure.py generate_flash_encryption_key --keylen 512 $ENCRYPTION_KE...

Hi, does that mean, that after read-protecting all efuses it is impossible to read the MAC with esp_efuse_mac_get_default() ? Is there any way to get the MAC? I mean WIFI need it to connect to a network or not? So there may be a way to get the mac-address after the WIFI hardware got it from the efus...

Hi,

I was able to solve my issue by moving some stuff like .bss to the SPIRAM. I did also some changes in the menuconfig, I can post them in a few days, right now I am traveling.
But you don’t have SPIRAM, right? Well, maybe it will help somehow.

Hi, could you solve the problem? I get the same error when I am connected to my WLAN, which worked just 2 days ago and I did not change anything. Today it is not working anymore with my WLAN. But it works when I use a hotspot of my phone. So the server-address seems to be correct and the problem mus...

Hi,

Are there any news on this topic?

Hi, I think I have the same issue with the MQTT client: I use an esp32-s3-wroom-1-n16r8 with idf 5.2.1. On core 1 I have a task, which uses SPI. On core 0 I have wifi and mqtt running. But as soon as I try to connect to the broker the esp crahses without any useful output (can post the logs tomorrow...

Hi, I have 2 esp32-s3-wroom-1-n18r8 modules. I am using GPIO11 as output and the pin is connected to ground via 20k pull-down resistor. Nothing else is connected. According to the technical reference this pin should be floating at start up, thus GPIO11 should be LOW on start up. This is indeed true ...

Hi, I did some measurements as you can see in the attached picture. You can see, that GPIO11 is somehow going high directly at startup. I have the same PCB (same batch from manufacturer) without these spikes. Can anyone explain this? Since we are about to start series production, I need to know what...

Hi, I have the same issue on GPIO11. Normally I would go by the Table 6.3 in Chapter 6.12 IO MUX Function List of the technical ref. manual. If I read that table correct your GPIO4 should be input disabled but does not have any pull-up or -down resistors at start-up. My GPIO11 is the same, except it...
