Hi baldhead, I think you can use the below API of esp-http-server httpd_sess_trigger_close() to close the socket fd. Please note, that a new wss example was added to esp-idf including a very simple keep-alive mechanism. This hasn't been yet published to GitHub, but will soon appear on the master bra...

Hi pascal21 Yes, that's correct. The IDF example "eth2ap" doesn't use network interfaces at all. It just connects the wifi driver to the ethernet driver, so the packets are directly passed from one to another without going through the TCP/IP stack (which has its benefits). Yes, it is possible to use...

Hi Justin2020, Yes, this is the expected behaviour. The reason for that is that both `httpd_ws_send_frame()` and `httpd_queue_work()` are executed from the same thread, and in addition to that (since the example runs these functions directly from the httpd handlers) this is also the httpd main threa...

Hi Baldhead, For asynchronous send from the ws server, you can use `httpd_queue_work()` as shown in the example with ws_async_send(). This is triggered as a response to some request (for testing purpose only), but could be used any time for any connected client. It only needs the httpd handle, and t...

Hi tabulous,

This example just demonstrates interfacing modems that happen to be in command mode after startup, so it is okay to sync first using generic AT commands and then create and start the ppp network interface after that.

Hi aderregibus lwIP uses the *default interface* for a socket to connect to, it is chosen based on user's API `netif_set_default()` provided the netif status is *up*. ESP abstraction to the interface routing (and to the TCP/IP stack in general) is a component called esp-netif, documented here: https...

Hi suifan.

Please check this comment: https://github.com/espressif/esp-idf/is ... -458254140
AFAICT this is still true, the actual https://test.mosquitto.org/ssl/mosquitto.org.crt 's signature algorithm is sha1WithRSAEncryption

Hi, Remote debugging works good with CLion on linux and macOS (in theory should also work on windows, but have never tried) * Go to Run->Edit Debug configuration - Add GDB Remote Debug - fill in GDB custom executable as xtensa-esp32-elf-gdb - setup target remote as :3333 - set Symbol file to the act...

There might be a related bugfix, not included in v4.0-beta2, but already on the release branch (https://github.com/espressif/esp-idf/commit/29690afc5799da7b7044e2304eb5a43652efa30c) Could you please check if that resolves the ping issue? (either using release/v4.0 branch or picking that commit to yo...

Hi growver, The mdns event handler is registered internally in mdns_init() here: https://github.com/espressif/esp-idf/blob/master/components/mdns/mdns.c#L4246. There's no need to register them in a user code anymore, nor use the `mdns_handle_system_event()` How does your mdns initialisation code loo...
