Re: Questions regarding flash encryption and Secure Boot
For download I use FLASH_DOWNLOAD_TOOLS_V3.6.4 You pushed me to the idea of writing a bootloader-encrypted.bin using espefuse.py Hello Yuriy, There is a checkbox called "DoNotChgBin" in FLASH_DOWNLOAD_TOOLS. When it is clicked, the firmware you want to download will not be changed by the SPI mode o...

Re: GPIO25 GPIO26
Hello Beb1969,
Yes. You should first turn off the DAC function. Then GPIO25 and GPIO26 can be used as common GPIO pin.

Hello xzwang,
How long did your ESP32 connect to AP? Is it sure to happen or happen by chance?

Re: ADC reference voltage on external pin?
Hi davidm,
The reference voltage for ADC is fixed to 1.1V. No other pins are allowed to use as reference voltage.

Re: ESP32蓝牙常开时的功耗估算。
Hello andre.liu,
我们的蓝牙跟wifi天线是同一根,时分复用的。
蓝牙的功耗已经在最新的datasheet中提到。功耗情况取决于你们对BLE的参数设置,每种模式下的功耗,我们都在datasheet中提到了。
谢谢您对ESP32的使用

Re: erase flash with flash download tool
Hello jumjum123,
That is quite easy. You have a blank.bin. Just copy and make it longer then you can get blank_1MB, blank_2MB and so on. Download this file using flash download tool.

Re: RF settings used by ESP32_FCC_WIFI_BT_20161129.bin
Hi espola,
Because bootloader of ESP32 starts from 0x1000, the sector is empty.
Thanks
