CC3200 ENT-WLAN example in the SDK doesn't write anything to UART

Other Parts Discussed in Thread: CC3200

Terra Term sees nothing on the COM port. It is not a connection issue, the UART example worked fine and so did the WLAN Station and AP examples. Not sure why this is happening. I have been using 115200 Baud.

Little bit of background: This is for an IoT project. I need to be able to use the CC3200 to connect to enterprise wifi with PEAP and WPA2. I know I need to flash the certificate. This querry is more for the serial port bug.

Thanks!

    Hi Sudip,

    Can you please work with the debugger, step into function 'Report' in uart_if.c and let me know where this gets stuck?
    Also, if NOTERM is defined in the project properties the logs would not be seen on tera term.

    Hi!

    Thanks for the quick reply! I know that if NOTERM is defined, it will not post anything through UART. My current workaround was to undefined NOTERM in both main.c and uart_if.c. Now it successfully writes to the port but I wanted to confirm that this will not have any other nasty sideeffects on any other functionality. I read on some other forum post that doing this caused the ENT-WLAN example to stop connecting to the WLAN It used to. Anything like that I should be aware of?

    Thanks!

    Hi Sudip,

    Not aware of any such issues. Logging any data on a terminal should not affect WLAN connection.

    Hi!

    On a related note, what was the certificate I need to flash onto the sFLASH of the device before I can connect to the ENT-WLAN? Is this compulsory to connect or can the CC3200 negotiate a certificate? I tried without the certificate and it refuses to connect. Any other common pitfalls?

    Thanks!

    I was told that the network I am trying to connect to doesn't require  a certificate to connect. But I still keep getting this error

    Any ideas why it cannot connect?
