Re: Problem enabling SecureBoot and FlashEncryption

The flashing steps mentioned here (esptool.py command lines or idf.py flash targets) will automatically append the "--after no_reset" option to stop the chip resetting into the firmware automatically after flashing is done. Hi, Is it possible to avoid the automatically append the "--after no_reset"...

Re: Why wpa_supplicant disable TLSv1.2 by default?

But disable it by default only hide the bug. People can enable it anyway and no body really knows what was the problem, and even the commit message is ambiguous. The problem is definitely not because "Some Enterprise Authentication Servers do not support TLS v1.2" as the commit log says. It would be...

Is there any API to get the auth mode of connected AP?

Hi,
I'm testing the smart_config example code.
It works fine and can join the target AP.
However, with smart_config example I only got SSID and PASSWORD.
I also want to get the auth mode of connected AP.
What is the recommend way to get the auth mode of connected AP?

Why wpa_supplicant disable TLSv1.2 by default?

In current master tree, wpa_supplicant: Disable TLSv1.2 by default. The commit log says "Some Enterprise Authentication Servers do not support TLS v1.2". Does it really cause problem if ESP32 enable TLSv1.2 but Enterprise Authentication Servers do not support TLS v1.2? I thought the TLS version is n...

Hi aderregibus

lwIP uses the *default interface* for a socket to connect to, it is chosen based on user's API `netif_set_default()` provided the netif status is *up*.
There is a known issue regarding routing for ppp interface that needs fix:

Regarding WiFi NVS flash enable flag

Hi,
It's not clear to me about the usage of nvs_enable flag of wifi_init_config_t
1. If nvs_enable is set, what kind of data will be saved to NVS?
What is the benefit of set nvs_enable?
2. In what use case the nvs_enable should be disabled?

Re: How to avoid accidental re-flash when secure boot enabled?

The ESP32 ECO V3 has an efuse to disable the UART loader entirely, but previous revisions unfortunately do not have this efuse. Is ESP32 ECO V3 ready for mass production? I check the website: https://www.espressif.com/en/products/hardware/modules The modules using ESP32 ECO V3 are marked as "RECOMM...

Re: Protection on the flash read

You can use any update mechanism you want as the update mechanism for encrypted programs is in the program itself. If you want to update using UART, you can modify your program to do this. I'm confused. If I enable flash encryption, can I upload an "encrypted firmware" via OTA? I might be wrong, I ...
