Space in WIFI SSID won't work

[OtherCroissant]

I have a space character in my WIFI SSID and it seems that the sensor will not connect. When creating a guest network without the space, the sensor connects. I found that there is a update for the ESP8266 to support spaces in the WIFI SSID, could you port this fix to the sensor firmware? See https://www.reddit.com/r/esp8266/comments/5pxivk/esp8266_ssid_with_spaces/

@CUnknown , have you by any chance tested unicode as well?

[OtherCroissant]

@YaguraStation Thank you for your fast reply, do you mean replacing the space in the SSID by '\u0020' ?

[YaguraStation]

Basically I'm talking about emojis - very commonplace in SSIDs these days. :dog:

[OtherCroissant]

I know about unicode, but I am not sure how I could enter it in the interface without it being escaped. I now used \\0020 and then it connects one time and then restarts (the same behaviour as with the normal space entered in de SSID). Any thoughts?

@YaguraStation This is the console output:

I also saw once that it got a valid ip adres for my subnet, but it still restarted.

Maybe building the sketch myself with the newer version of the ESP8266 wifi stack would do the trick, I will try that in a bit...

[YaguraStation]

Yeah, sorry, didn't want to overflow the thread... but will also attempt to at least reproduce the issue and test emojis sometime this week.

[YaguraStation]

I could reproduce problems with space in SSID.

Funnily emoji in SSID works fine, though.

@CUnknown Space should work now (since version NRZ-2018-103). Please close issue if it's okay.

[OtherCroissant]

@ricki-z Unfortunately, still no luck. After configuring the WIFI network, the console output displays that it acquired a IP address on the network, but after storing the config, it needs to restart. After the restart, the device is not able to connect tot the WIFI network with a space in the name again.

[ricki-z]

@CUnknown Should work with new actual release NRZ-2018-105.

[ricki-z]

@CUnknown can we close this issue?

[RoTahnWaurie]

@ricki-z With NRZ-2018-111 this issue occurred for my sensor, too. I installed the sensor last month with NRZ-2018-107 without any wlan problems. After the automatic update from september 20th it won't connect to my wlan with an whitespace in the SSID.

Any idea how to fix this - without changing the SSID?

I don't have the issue, last Saturday (22th) I installed version 111 on two new ESP boards. No problem with the connection to my network (with space in SSID). I do have an issue with access to Madavi.de, looks like the website is unavailable?

Sorry, my issue seems to be a problem with 802.11n only configuration of the wlan NOT with spaces in the SSID. With 802.11b/g/n mixed wlan configured the sensor connects.

[ricki-z]

The NodeMCU is working in 2.4 GHz wifi networks only.

[RoTahnWaurie]

Thanks for the info, but my AP is 2,4Ghz only and was configured to use 802.11n only. The NodeMCU Lolin V3 worked fine for about a month with this setup until update NRZ-2018-111.
