ESP32 D requires router restart to connect to WiFi network

We have 2 boards with ESP modules which need to work together as part of same LAN to provide a solution. One board uses ESP Wroom 32 and other uses ESP Wroom 32 D with external antenna. We are using same ESP IDF FreeRTOS IP stack for both the systems and the code to initialize and maintain WiFi conn...

Re: PSRAM Free heap memory reduced upon using UART with RTS,CTS Pins set

Sorry for my ignorance. The data has been allocated from the system calls and it is not freed yet because the related queues and other buffers are still functional by the time I end the trace. I think the reduction is memory is instant the moment I assign PSRAM GPIOs to UART driver. May be the gradu...

Re: PSRAM Free heap memory reduced upon using UART with RTS,CTS Pins set

Sorry for the delayed reply. I have done the heap tracing as suggested. I can see that the data is being leaked from freertos system calls. I have not done any dynaic memory allocation in my code. Below is the details of the trace. I have only posted the debugging part of the logs. This is happening...

PSRAM Free heap memory reduced upon using UART with RTS,CTS Pins set

Hi, I am using esp 32 wrover for my project. I have enabled PSRAM to make use of external RAM and set the memory to be automatically allocated as part of the malloc() function call (the default option). When I initialized my code without UART I used to have the complete free memory which is more tha...
