Can't connect to wifi access point with space in SSID

[GeeF]

Hardware:

Board: ESP32 Dev Module
Core Installation/update date: 14/nov/2017
IDE name: Arduino IDE
Flash Frequency: 80Mhz
Upload Speed: 115200

Description:

Connection to a WiFi access point fails, if the SSID contains a space.

Sketch:

use the example client sketch

I don't think that SSID should contain space at all

[GeeF]

Have a look at standards.ieee.org/getieee802/download/802.11-2012.pdf
Section 8.4.2.2: "The length of the SSID field is between 0 and 32 octets".
So it is basically just a 32 byte buffer that can be interpreted as UTF-8.

If it can't/shouldn't/wouldn't work for the esp32 implementation, it should at least be documented somewhere so people don't run into it.

all in all, Arduino calls the API exposed in IDF. Arduino itself does not limit you to "no space in name". I will try to contact the WiFi engineers and see what they can do.

Thanks :)

@GeeF Arduino calls the API exposed in IDF. Arduino itself does not limit you to "no space in name". So I tested in IDF, I can connect to a WiFi access point successfully, if the SSID contains a space.

I have just tried again with a different AP and it works. Seems to be something fishy about the other AP I’ve been using.
Sorry to have wasted your time

Hi, I was the same issue like @GeeF and in my case I have setup the tkip flag in wireless security profile.
May helps some one.

Regards.
