If we believe Espressif’s description ofexternal PSRAMthen the 4MB limit is rather based on silicon limitations than limitations in the ESP-IDF framework. The page states “It can be insufficient for some purposes, so ESP32 has the ability to also use up to 4 MB of external SPI RAM memo...
I am using Bluedroid BLE stack in order to do BLE with an Esp32S3 chip and everything is ok. The stack runs normally, I have no problems with it. Now, I would like to enable Wifi in SoftAP mode when the chip starts in order to have the possibility to upgrade the firmware via OTA...
Do I need to do something at menuconfig to use this PSRAM as IRAM? TLTR; As specific, I want to use ESP32-WROOM as bluetooth classic + low energy module while any other functions(like WIFI) are disabled. I visited ESP-AT document and enable BT at command, and built the ESP32-AT ...
Hi everyone! In my application i have two ESP32 WROVER. One in Sink mode and the other is the Source. The Source is able to startup, connect and stream the music. It's OK. But at the end of the current file i need to go to the next track...
If you enable that, you can mark variables to live in PSRAM BSS rather than internal BSS. Example: Code: Select all char very_big_variable[1024*1024]; would become Code: Select all #include <esp_attr.h> ... EXT_RAM_BSS_ATTR char very_big_variable[1024*1024]; to allocate it ...
