I'm writing a file downloader routine where I have the http client event handler save downloaded file to a RAM buffer. When that is full, I write it to sd card, start from the beginning of the buffer to fill it again until their is no more data. So the HTTP_EVENT_ON_DATA handler reads and dumps data...

I'm sorry. I think my project changed direction and I didn't continue on the httpd route. I looked up what I wrote down and nothing.

I didn't notice this until now. Whenever I make, win 10 antimalware executable runs at a high CPU % and memory size. When make completes, this drops down. Any reason for this? Any way to make changes?

Thanks for the help. I did some digging and found this include file: esp-idf/components/bootloader_support/include/esp_flash_partitions.h It has the states and the data structure defined as below: /// OTA_DATA states for checking operability of the app. typedef enum { ESP_OTA_IMG_NEW = 0x0U, /*!< Mo...

This post is about how OTA rollback didn't work for me and how I made it work. If you have more ideas than me please respond with corrections. If you're just getting started with OTA rollback, this hopefully gives you some guidance. I have the "enable rollback" enabled in menuconfig, compiled app an...

I'm learning OTA. It seems that the simple https_ota is not hard to incorporate in my existing project (after much reading and testing of course). On the other hand, I didn't not observe rollback (I didn't enable it first). I'm now interested in understanding the otadata partition data format. For n...

Sorry I didn't get back to this issue sooner. I actually was having an overlap of pin definitions. I tested with only a simple code so I defined SPI pins using these: #define SPI_PIN_MOSI xx But once I combined my code into my existing project, there was already this #def but they are used to define...

What about default headers? What headers and values are included? I tested: Host:xxx is included by init() Content-length:xxx is added by perform() Content-Type: application/x-www-form-urlencoded is also added by perform() when using POST method Connection: is not included User-Agent: is not include...

How many headers can I add to the esp_http_client? Is it limited only by memory, with some sort of linked list structure? The doc is very bare. No example snippets at all on headers. I figured out my answer with the source code. In case you wonder or you have comments. Here is what I found from http...

I recently completed a short project calling the SPI master library in C. Everything worked. Now that I moved to C++, things fail, i.e. I no longer get the same response as before, just some 0xFF. I need to look into maybe testing some very simple SPI transactions first but just in case this library...
