ESP32C3 efuse: what is the difference of DIS_USB_JTAG and DIS_USB_SERIAL_JTAG

If DIS_USB_JTAG=1 && DIS_USB_SERIAL_JTAG=0 && DIS_USB_SERIAL_JTAG_DOWNLOAD_MODE=0,
does this mean allow download image via USB serial but disable the JTAG functionality?

Re: ESP32-C6 开发板选型问题

Is the ESP32-C6 module already in mass production or still in sample stage?
When will the ESP32-C6 module get CE and FCC certificates?

Re: ESP32 DHCP 获取不到IP

I hit the same issue on one device. My log is similar to https://esp32.com/viewtopic.php?f=25&t=26360&start=30#p93297 And compare to working devices, I found the working device will show below message: I (19728) wifi:<ba-add>idx:0 (ifx:0, ac:84:c6:32:1a:26), tid:6, ssn:2, winSize:64 dhcp_recv(pbuf =...

The problem is solved. In ESP-IDF v4.4.x, you cannot use the name "ctx" of the encryption context variable. If you use a different name, then everything works.
Why? Is ctx a global variable?

Re: RTC reset on deepsleep wakeup - ESP32-C3

Sorry for the late reply and thanks for asking! RTC should not be reset when the chip is woken up by a GPIO from deep-sleep mode. This happens because there is a bug in ESP-IDF code. The bugfix has already merged to the master branch, and is to be backported to other release branches soon. Could yo...

Re: ESP32-S3 as BLE HCI-UART Host only

NimBLE supports "BLE HCI-UART Host only" case.
I'm sure it's working because I already use it for my project.
Maybe you can create a feature request in esp-idf.
