Re: How to Scan ADC's 8 Channal in High Speed?(maybe 100-250 ksps per channal?)

Re: http server async response and keeping socket open

i figured you can't really mix httpd_resp_* with httpd_default_send ... if you want to use the later you should only use the later and also send correct HTTP headers first.

i narrowed it down to this code inside response handler not working: const char* str = "event: test\ndata: test\n\n"; int resp = httpd_default_send(req->handle, httpd_req_to_sockfd(req), str, strlen(str), 0); printf("sent with: %i", resp); httpd_default_send does not return error (resp is correct le...

http server async response and keeping socket open

Hello, i would like to implement EventSource in http server, which requires me to keep the connections open and send data to them at later time. I tried several aproaches so far: - getting `fd` and `hd` from `req`, storing them and using them later from another function later with `http_default_send...

multiple definitions of 'operator|='

Recently i installed esp idf on new machine, thus upgraded to latest version with cmake and gcc 8.2.0 however my project now no longer builds. it compiled ok, but when linking i get the following errors: /home/user/.espressif/tools/xtensa-esp32-elf/esp32-2019r1-8.2.0/xtensa-esp32-elf/bin/../lib/gcc/...

Re: bluetooth code size enormous

i tried to compile esp-idf example to verify the size .... and its 715kb (compared to 950kb with arduino) ... still quite huge for something that doesn't do much (if you want to use OTA with it ... you have like 300kb left for your other code (and other libs ... like wifi and stuff) ... but running ...
