How to use the upper 4MB of ESP-Wrover 8MB PSRAM

Hello, I am using an ESP-Wrover-Kit. It has a 16MB external SPI flash and an additional 8 MB PSRAM. In the datasheet, it is mentioned that up to 4 MB of PSRAM can be mapped into CPU data memory space at a time. As only 4 MB memory space is considered for External SRAM (0x3F80_0000 to 0x3FBF_FFFF), h...

Wake up from sleep using Android App via bluetooth or wifi

Hello, I know that the BLE Stack make use of various interrupt sources, i.e. timers, clocks, BLE radio events. So I'd like to know that is there way to wake up ESP32 from BLE or WiFi connection I think that the BLE doesn't cause an instantaneous interrupt like a hardware interrupt from the ESP32 , b...

I try to connect ethernet with static ip first, and if it does not connect, I want to connect with dynamic ip.

Hello I was working on project using esp32 wrover-e with PlatformIO v4.4.1 and Arduino framework. I try to connect ethernet with static ip first, and if it does not connect, I want to connect with dynamic ip. How can I get Ethernet to work like the above scenario? I think I need ETH.end().
