httpd: serving gzip index.html
I have an index.html that has grown to 88KB but will gzip to 23KB. ESP-IDF 3.3 release. If there anything I can do without digging into and modifying the httpd source code to signal that the file being served is gzipped? esp_err_t index_html_get_handler(httpd_req_t *req) { httpd_resp_send(req, (cons...

APSTA - time before network shows in Windows
What settings (if any) might influence the time it takes for the AP to show in Windows or Android when they scan for networks? It can take a few seconds to appear even when the ESP32 has been powered for a while.

Re: power save in esp32 with running can bus
AFAIK you cannot power save whilst being able to receive on CAN without losing data, unless the ESP32 is the only device on the bus doing the ACK, then there should be retransmits. You can wake the ESP32 on CAN bus activity due to change in level on the Rx pin.

Re: Store Certificates in encrypted partition , how ?
NVS as blob to avoid string limit. There is an Espressif tool to make NVS partition data.

Re: Experiement to load/execute compiled C code into RAM
It worked, but I did not continue using it. Doing an OTA update of all the code and data together was easier to use and support for our application. Run time scripts were small and fast by parsing them with std::string so did not have to bulk it with and learn Lua etc.

Re: OTA of factory image
Dev boards from various sources might have firmware, but modules we had from Espressif directly do not and this is the standard AFAIK.

Re: Is it recommended/practical to use C++ instead of plain C ?
I use std::map, std::string, std::vector, find and iterators. The error messages are not nice and some things need just as much care for memory management as malloc/free because you can easily run out of PSRAM, it comes down to design and algorithm, and appropriate use and I would not criticise C++ ...
