TI CC3200 Launchpad – Quick Guide
Out Of the Box feeling
OOB application is very nice, you can connect to the AP without security and then you go to the 192.168.1.1 (or http://mysimplelink.net , as indicated by TI, if you think that’s shorter…). Here answers a small webserver that serves some (uncompressed) html files that are a frontend to the configuration settings and also some nice demo programs and documentation.

Flash the Exosite firmware on the CC3200 Launchpad
- Profiles won’t be saved if the WPA2 key is too long. Even in OOB Fw.
- Flashing without format won’t work.
- Formatting various sizes (1MB, 2MB, 4MB, 8MB, 16MB from Format Options window that comes after you push Format button) leads to strange results, my CC3200 Launchpad has responded well only on 4MB. Even the OOB was unable to restore the board without reformatting to 4MB.
- I noticed that sometimes the CC3200LP communication enters in a strange mode, appearing offline to Exosite and the Dashboard is showing up some negative temperatures. The LP responds to ping, the uptime displayed by the http server is ok. Only a power cycle reset solves it…
- Select COM port, put jumper on SOP pins, verify using Get Version (
Reset push-button required).
- Formatted 4MB, nothing else checked.
- Apllied Service Pack Update.
- Flash the desired firmware.
- Remove SOP jumper. Put on the AP Jumper (VCC-P58)
- Connect to the AP without security
- Create a Profile with the local WiFi configuration (SSID, Key) and give it a index number. Save.
- Reset the board and wait the boot and connect sequence.
If you try to restore the OOB firmware, you get the original status by opening with Uniflash the out_of_box.ucf that comes in the CC3200SDK\cc3200-sdk\example\out_of_box\html folder.

- Connection issues are mainly because of the SOP (Sense On Power) Jumpers. Flashing/Programming can be done with 100 configuration, that means only one jumper, placed on position labeled 2.
- Using the programmed configuration will be done removing that SOP jumper
- Uniflash 4.0 can’t be used for CC3200, use instead the old 3.4.x version
