Get Time Example Program Connection to AP failed

Hi Kel,

You are using old version of service pack. request you to update the service and try.

Regards,
Ankur

Hi Ankur,

    I downloaded the Service Pack from this link below. Service Pack Version Date March 12, 2015

   

    I got the same errors. Comparing the log from Tera Term from my first post the build version is now 2.4.7.2.31.1.3.4.1.1.5.3.34. Should I try the Beta version? I first formatted my CC3200 LP with XCC3200HZ MCU and then program the service pack, then run the program at CCS.

Ankur Baranwal - From the Release Notes link below, I should not encounter any problem because I am using XCC3200HZ MCU

processors.wiki.ti.com/.../CC32xx_Release_Notes

- kel

Ankur Baranwal - httpserver example program works. So, it seems this error only happens when the program uses Network_IF_XXXX API's.

Just additional info, at common.h, I set WPA for Security Type as per my wifi router settings.

#define SECURITY_TYPE       SL_SEC_TYPE_WPA/* Security type (OPEN or WEP or WPA*/

Hi Kel,

In file 'network_if.c' in function "Network_IF_ConnectAP" just before calling "Network_IF_IpConfigGet()" can you print the value of 'g_ulStatus'.

Also request you to try running 'get_weather' or 'email' example.

Regards,
Ankur

Ankur1 (3494968) - 

g_ulStatus = 10

The -409 return is from sl_NetCfgGet()

Hi Kel,

Just to confirm have you modified anything in the host driver or SDK example project?

The error codes (-409 and -412) are not related to the API you are using. I am checking this error internally with team and get back.

In the mean time can you please comment the call to function "sl_NetCfgGet()" in "Network_IF_IpConfigGet()" and test again.

Regards,
Ankur

Ankur Baranwal - No, I have not modified the CC3200 SDK example projects. This is what I did recently.

1. Downloaded and Installed latest CC3200 SDK 1.1.0. My Service Pack is Version 1.0.0.1.0 
2. Deleted CCS folder installation and installed CCS 6.1.0 using offline installers.
3. Followed CC3200 Getting Started Guide.
4. Tested httpserver successfully.
5. Tested Parse quickstart example program successfully.
6. Tested blinky example program.
7. Error with hibernate
8. Error with Get Time - This is when I made this post
9. Downloaded and program March 12, 2015 Service Pack Release
10. Error with Get Time
11. Error with Get Weather
12. Error with Email.

Later I will download fresh copy of CC3200 SDK 1.1.0, turn off antivirus and install. I will check, if I get the same error message.

- kel

@Ankur1 - I commented out these lines at network_if.c

//
// Get IP address
//
//lRetVal = Network_IF_IpConfigGet(&ulIP,&ulSubMask,&ulDefGateway,&ulDns);
//ASSERT_ON_ERROR(lRetVal);

//
// Send the information
//
//UART_PRINT("Device IP Address is %d.%d.%d.%d \n\r\n\r",
// SL_IPV4_BYTE(ulIP, 3),SL_IPV4_BYTE(ulIP, 2),
// SL_IPV4_BYTE(ulIP, 1),SL_IPV4_BYTE(ulIP, 0));

I got this output at TeraTerm. Somehow the Get Time was almost successful. So I guess there is something wrong with Network_IF_XXXX API's. I think you can duplicate this if you have the same setup as mine.

Hi Kel,

-159 Error in above case corresponds to no response fro DNS querry.
Does the network with which device is connected to has internet access?

Regarding the initial error with ' sl_NetCfgGet()' API:
- Can you please revert the initial changes in 'network_if.c' and make following changes.
in file 'network_if.c'
@ line 1108
SlNetCfgIpV4Args_t ipV4 = {0};
lRetVal = sl_NetCfgGet(SL_IPV4_STA_P2P_CL_GET_INFO,&isDhcp,&len,

Hi Ankur,

The CC3200 LP is connected to a network that has internet access. I have mentioned here that I was able to test wlan station example program successfully. Here is the tera term output with the modifications you requested.

Can you please confirm if the printed value "192.168.254.102" is indeed the IP acquired by the device. Also request you to put a breakpoint and confirm the gateway IP filled by API 'sl_NetCfgGet()' is correct.

For DNS loopup failed error, can you try changing the SNTP server in the application?

Regards,
Ankur

Hi Ankur,

I am able to ping 192.168.254.102. The ipV4.ipV4Gateway is 0xC0A8FEFE.

I change the SNTP server and now able to Get Time. This happens with the modifications you suggested. If original code, I get the error.

Kel,

It looks like 'sl_NetCfgGet()' API is returning the junk error code but populating the correct values.
I will check this internally with team.
For now you can comment out the error return check for the this API in code.

Regards,
Ankur

Ankur1,

I will "comment out the error return check for the this API in code". Thanks for your support. But, I will not "Verify Answer" yet this post since there is no explanation yet why I am getting the "junk error" code. If I am getting this error, most probably others with the same setup as I am, will also get this error.

Ankur1 said:

may lead to this issue

The issue happens every time I run Get Time example program. So, "may" is not the right word to describe it. I am not greatly affected by this issue, so I am okay with just fixing it with code modification. But, maybe others who use Rev 3.2 CC3200 LP for their product development are. Anyway, thanks for your support.
