Hi I have a project using ESP32-S3 modules and IDF. I want to use the PSRAM as memory which is non volatile across a CPU reset. I understand it is NOT non volatile over a power loss. I want to be able to store data records in a FIFO type structure. What is the best strategy for doing this? A VFS RAM...

Thank you. I searched the API spec back and forth but somehow completely missed this.

Hi I need to multiplex a serial port to drive 3 separate physical serial interfaces with separate baud rate setting etc. My application is the master and polls the 3 devices so can manage only talking to one device at a time. I have plenty of GPIO spare so rather than add gate hardware to enable and...

I need the header block in the .bin file which contains the version number, build date and build time to update. As I have said a few times it does not update unless I do a "clean build". This header record at the start of the BIN file is referenced by my OTA code as part of the update management. Y...

Thanks but as I said, I already have this solution for MY code, my question is regarding the the IDF framework which generates the bin file header as used in OTA.
Does anyone from Espressif service this forum?

My questions was specifically "I am using OTA via HTTPS and am referencing the bin file header build date and time so I need this to be correct for management purposes." Obviously the bin header file is not part of main.c

Someone from Espressif must be able to answer this question PLEASE!

Gee that would be great and what I expected originally. But it is not the case. I have a file called super.cpp which references __DATE__ and __TIME__ If i only change main and then rebuild the project (not clean build), the date and time referenced in super.cpp do not update, (as the contents of sup...

Thanks for responding. I don't understand your response though. I have to make a change to a file which uses __DATE__ or __TIME__ to get it to recompile this specific file otherwise they do not update. Making changes to another file will build that file but not globally update __DATE__ and __TIME__?...

I am using ESP IDF version 5.3. If I do a make clean and full build , the build date and time is updated in my project where I reference __DATE__ and __TIME__ as well as in the project bin file header. But if I don't do a full build, the build date and time do not update. I know which file I need to...

I am working on a ESP32 MQTT5 WiFi Mesh project using IDF. I am running the same software in my MESH_ROOT as I am in my MESH_NODE both using ESP-32-S3, with a Mosquito broker on a local LAN PC. I am finding if my client Host (PC App) sends some medium size payloads eg around 420 bytes in quick succe...
