SSID with Chinese characters - CC3200 Launchpad / Xively / Azure Stream Analytics

Other Parts Discussed in Thread: CC3200, UNIFLASH

Many Wi-Fi hotspots in China have an SSID with simplified Chinese characters for example "威灵顿酒店" which means "Wellington Hotel".

I tried CC3200 Launchpad with Xively demo code given https://xively.com/partners/ti/. Works fine with any SSID with english characters, including my smartphone Internet Sharing, but no luck trying to enter SSID 威灵顿酒店.

SSID 威灵顿酒店 works phone with my Laptop and Smartphones where I just have to click to select the network.

I tried Tera Term and Hyperterm but no luck as CC3200 launchpad refuses to echo the Chinese characters.

I am thinking of changing the source code but before doing that I need to understand how to deal with Chinese characters in the source code.

Any recommendation for addressing this situation? I guess the Chinese market is huge enough for this topic to receive some attention

    Have you tried using SmartConfig? When I was in China I had issues with getting SmartConfig to work with Chinese Routers (with the CC3000), once I changed my iPad to Chinese Language, I was then able to use SmartConfig.

    This may not solve your original issue, but it is another thing to consider, since SmartConfig will likely be the best way to connect to Wifi Routers. 

    As another test, what happens if you try provision using Access Point Mode, that is by using the internal CC3200 web pages? This will help narrow the issue down, depending on whether this works or not.

    By the way, since you are working with Azure Stream Analytics, I think you will be interested in my CC3200 and Azure IoT End to End Proof of Concept. It includes all required code, detailed steps  and a SAS Token generator so you can authenticate with Event Hub's REST API (which is what Stream Analytics will consume)

    Hi all,

    I succeeded using SSID with Chinese characters with the Exosite CC3200 cloud demo.

    I followed the instructions at: https://support.exosite.com/hc/en-us/articles/202271424--CC3200-Wi-Fi-Launchpad

    I used the Exosite Cloud Demo available in : https://github.com/exosite-garage/CC3200CloudDemo/tree/v2/

    Uploaded in CC3200 using TI Uniflash

    Forced the AP mode with jumper pin 58 to VCC+ as per TI instructions

    Connected TeraTerm and checked the dialog with CC3200

    Connected my PC Wi-Fi network connection to the “mysimplelink-XXXXXX” access point (Windows 8.1) - Note that CC3200 is now a Wi-Fi hotspot with SSID “mysimplelink-XXXXXX” so your PC can connect to it.

    Open my PC web browser

    Navigated to http://mysimplelink.net for viewing the TI SimpleLink website managed on the CC3200

    Took note of the MAC Address which is needed later to link the device to Exosite account

    Navigated to the profiles page to enter the SSID

    Did a copy-paste of the Chinese characters “威灵顿酒店“ of the network SSID I wanted to connect to + selected the security type

    I also added a profile for connecting to my Smartphone shared Internet (when I am away from Hotel)

    Etc…

    Configured Exosite as instructed…. Not forgetting to paste the MAC address noted previously

    … and immediately temperature started to be acquired and displayed on Exosite!!!! -- From my hotel room in a small town in China!!!!

    All is good. Next step is to modify the CloudDemo code to add more sensors (humidity, pressure, GPS)

    Have fun. Thierry
