ESP IDF: Station + soft-AP (WIFI_MODE_APSTA) There is no working example - why? Where is?
Re: ESP IDF: Station + soft-AP (WIFI_MODE_APSTA) There is no working example - why? Where is?
In follow up to my previous post, adding in a few time delays between tearing down AP and starting STA helped. Also, I turned off nvs_flash for WiFi as I think that was causing the corruption when starting in STA mode.
Here's my menuconfig changes.
[OFF ] Wi-Fi -> WiFi NVS flash
[OFF] Phy ->Store phy calibration data in NVS
I was seeing brownouts earlier in the transition and increased
[2.7v] * ESP32-specific -> Brownout Voltage Level
For debugging
[On] WiFi -> Enable Wifi debug Log
[Verbose] WiFi -> WiFi debug log level
If anyone has seen similar issues when trying to use both WiFi modes, please share if you had any better resolutions.

This works well for string parameters.
Tell me, how to properly set the WiFi channel in the Access Point mode?
Code: Select all
strncpy((char *)ap_config.ap.password, configDev.apPSK, strlen(configDev.apPSK));

That is... I don't think you understand what that does exactly and why one would use strncpy. Str[n]cpy already stops copies as much bytes as are in configDev.aPSK; to specifically set it as a limit with the strlen parameter does nothing useful. In contrast, if configDev.apPSK is too large, you can overwrite the memory of ap_config and corrupt stuff and make your app crash and your strncpy will do nothing to stop it. Correct method is:mcmega wrote: ↑Tue Dec 22, 2020 1:45 pmThis works well for string parameters.Code: Select all

strncpy((char *)ap_config.ap.password, configDev.apPSK, sizeof(ap_config.ap.password));
Wrt your question: as the docs indicate, the ap_config.ap struct has a channel member, so it would be
Code: Select all
ap_config.ap.channel=4;

Re: ESP IDF: Station + soft-AP (WIFI_MODE_APSTA) There is no working example - why? Where is?
Hello,
Did any one find a proper solution for accessing both AP and STA mode ? Once AP mode is getting after receving SSID+PASS , i am facing issue for station mode.
If any one could suggest please help me out.
Thanks in advance

Hi,
i'm also looking for a good solution, it would be great if you could just stop "offering your help" and provide a simple example instead because you said it would work....
With the current exmaples it is/was not possible for me to provide a SoftAP (that worked) and also to connect to a available WiFi.
It would be awesome if you could just share your proposed working snippets.
Thanks in advance.

Sorry, it took me some time to prepare the example. The following code snipped should be able to create an AP an also connect to a available WiFi - it would be great if you can tell me, what i'm doing wrong.
Thanks in advance,
