Other Parts Discussed in Thread: MSP430F5438, MSP430F5438A

Hi,

I have two questions.

1.
I use MSP430FR5739 to updated CC3000 firmware last week.

I use MSP430F5438 to link CC3000 now.

When I do first time config in Basic Wi-Fi example code,It can’t work.

It is ok to do  first time config before I updated CC3000 firmware.

How can I do?

2.
In my project, I need to use TCP protocol to send packet to server. I use  Basic Wi-Fi example code.
I can use UDP protocol to send now, but TCP can not work.
In other post on e2e, someone have the same problem like me.
He told me if use wlan_connect() function, the problem will happened.
So I want to use wlan_add_profile() function to try.
I don't know if I use  wlan_add_profile() ,Should I need to use SmartConfig to change policy by use  wlan_ioctl_set_connection_policy () function?
Could you give me step by step to do?

I try this code, but it is not work.Should I need to use SmartConfig ? But I can not use first time config now.

wlan_add_profile (WLAN_SEC_WPA2,"TP-LINK", 7, NULL, 0,0x18, x1e, 0x2, "sifra123", 8);
wlan_ioctl_set_connection_policy (0,0,1);
wlan_stop();
__delay_cycles(600000);
wlan_start(0);

Thanks for your help

Hi Edward,

Thanks for moving your post to a new thread :).

1) Have you updated the firmware with the latest version of the patch programmer (v1.10.1)? I would recommend updating with the latest version of the patch programmer and then trying to use smart config to configure the CC3000 to associate with your AP. You can find the latest version here: http://processors.wiki.ti.com/index.php/CC3000_Wi-Fi_Downloads

2) For context, could you link to the e2e post that you are referencing? It may be helpful to read how the WLAN APIs function in the context of adding profiles and how the Socket APIs function (nearly identical to Berkeley APIs). You can find more information in our CC3000 Host Programming Guide wiki here: http://processors.wiki.ti.com/index.php/CC3000_Host_Programming_Guide#CC3000_WLAN_API

http://processors.wiki.ti.com/index.php/CC3000_Host_Programming_Guide#CC3000_Socket_API

The Basic Wi-Fi example code uses UDP to transfer data, so if you want to use TCP you'll need to change the basic_wifi_application.c code so that the arguments you pass into the socket() function reflect TCP instead of UDP. As an example, you may wish to look at the SensorApplication code from the First Time Getting Started Guide since it uses a TCP socket to pass data to a TCP server.

Hope that helps,

Keegan

Hi Keegan,

1) I can't do first time config when I finissh to update firmware v1.10.1.

I can do first time config before I update firmware.

I use MSP430FR5739 to updated CC3000 firmware, but I use MSP430F5438A to link CC3000 in my project.

Is it a problem?

2) When I didn't update firmware,I use this api wlan_ioctl_set_connection_policy (1,0,0).

I can connect any AP ,but now I only can connect assign SSID by use wlan_connect() function.

I wnat to use profile to connect AP now.

But I am not sure if I want to add profile,doI need to use wlan_add_profile in first time config function?

I try many times,but it seems not success.

3) I Follow the steps involved in sending the TCP packets,

Open the socket: socket (AF_INET, SOCK_STREAM, IPPROTO_TCP)
Connect to the destination server: connect (ulSocket, &tSocketAddr, sizeof(sockaddr))

3. Send data: send(ulSocket, pcData, ulDataLenght,0)

There is no data in Wireshark, but I can see TCP connection in Wireshark.
UDP is ok to send.

Thank s for your help!

Hi Keegan,

About question 2, I describe completely.

When I want to change policy and add profile, I only should restart CC3000 or I need to do first time config again.

Edward,

To answer your questions:

1) I do not see this being an issue, the code on the CC3000 EEPROM should be agnostic to the host processor being used. Can you confirm that you flashed your CC3000 module in the correct order (driver, then firmware) and saw the correct LEDs light up after each step?

2) When you set the CC3000 to auto-connect using wlan_ioctl_set_connection_policy (1,0,0), you will not be using any profile that smartconfig has created.

How to use SmartConfig:

Before running SmartConfig, you should have the connection policy reset using wlan_ioctl_set_connection_policy (0,0,0). Once SmartConfig is run, it will automatically set-up a profile for you. Next, set your policy to use profiles by using wlan_ioctl_set_connection_policy (0,0,1), then reset the CC3000 using wlan_stop() then wlan_start().

If you are trying to switch between policies (i.e. switch from Auto Connect to using profiles) you must reset the CC3000. From the wiki link I posted earlier: "The device must be reset before a policy can be applied. Profiles must first be added to the CC3000 device before they can be used."

Hope that helps,

Keegan

Keegan,

Led light up correctly.

I means when I finished update firmware, I use wlan_ioctl_set_connection_policy (1,0,0).

It can not auto connect AP, but it can auto connect AP when I don't update firmware.

About add profile and SmartConfig:(This is my step by step.)

ulSmartConfigFinished = 0;
ulCC3000Connected = 0;
wlan_ioctl_set_connection_policy(0,0,0);

wlan_add_profile (WLAN_SEC_WPA2,"TP-LINK", 7, NULL, 0,0x18, x1e, 0x2, "sifra123", 8);

wlan_first_time_config_set_prefix(aucCC3000_prefix);

wlan_first_time_config_start();

wlan_ioctl_set_connection_policy(0, 0, 1);

wlan_stop();

wlan_start(0);

wlan_set_event_mask(HCI_EVNT_WLAN_KEEPALIVE|HCI_EVNT_WLAN_UNSOL_INIT|HCI_EVNT_WLAN_UNSOL_DHCP|HCI_EVNT_WLAN_ASYNC_PING_REPORT);

Could you help me to check my code?CC3000 can not use the profile that I add.

About sending the TCP packets:(This is my step by step.)

socket (AF_INET, SOCK_STREAM, IPPROTO_TCP);

Connect to the destination server: connect (ulSocket, &tSocketAddr, sizeof(sockaddr));

send(ulSocket, pcData, ulDataLenght,0);

I only use CC3000 be a client,so I don't need use recv().

The connect function return error, the send function return correct bytes.

What's wrong about my connect function?

I am sorry to ask many questions.

Many thanks!!

Edward,

Okay I think I figured out what is going on:

1) The wlan_first_time_config_* functions are deprecated and have been replaced by wlan_smart_config_* functions.. Are you certain that you are running the latest versions of our CC3000HostDriver and CC3000Spi code sets? That could be why your smartconfig code is not working after you have flashed to the latest firmware.

2) When wlan_first_time_config_start() is run it is setting up a profile on the CC3000, you do not need to run first_time_config/smart_config related functions if you are assigning your own profile. So you will not need to run:

wlan_first_time_config_set_prefix(aucCC3000_prefix);

wlan_first_time_config_start();

or their wlan_smart_config_* equivalents.

At a glance, your step-by-step for sending TCP packets looks okay.

Best,

Keegan

Keegan,

About TCP send packet:

Connect function is returned error,not returned 0.

I can not see any data packet in wireshark.

UDP is ok in wireshark to see data that I sendto.

Keggan,

I add profile still not work.

Proirity set 0 is ok?

Does my code is anything wrong?

wlan_ioctl_del_profile(255);

wlan_ioctl_set_connection_policy(0,0,0);

wlan_add_profile (WLAN_SEC_WPA2,"TP-LINK", 7, NULL, 0,0x18, x1e, 0x2, "sifra123", 8);

wlan_ioctl_set_connection_policy(0, 0, 1);

wlan_stop();

wlan_start(0);

wlan_set_event_mask(HCI_EVNT_WLAN_KEEPALIVE|HCI_EVNT_WLAN_UNSOL_INIT|HCI_EVNT_WLAN_UNSOL_DHCP|HCI_EVNT_WLAN_ASYNC_PING_REPORT);

By the way,I have 2 CC3000. I use old version now,because the code for MSP430F5438A is not update.

Many thanks

Edward,

Have you updated to the latest CC3000HostDriver and CC3000SPI code sets?

0 Edward Hsiung over 12 years ago in reply to Keegan@TI

Keegan,

I have two CC3000, one don't update firmware.

So I use older version code to link the cc3000 don't update firmware.

Do you think that is a problem?

Thanks a lot.

Keegan,

I use new code in IAR.

From IAR when I try to make BasicWiFiApplication:

IAR show error as below

[Og007]: Assembler list file generation not allowed in this version of the compiler
Error while running C/C++ compiler
board.c
[Og007]: Assembler list file generation not allowed in this version of the compiler

Edward,

These errors may occur for several different reasons. IAR might not be looking in the right directories for project files, or you may not have built the CC3000 code libraries in the correct order. In short, this error has occured because your project workspace is not set correctly. Have you followed the build steps in the wiki? http://processors.wiki.ti.com/index.php/CC3000_Basic_Wi-Fi_example_application_for_MSP430#Running_Basic_WiFi_Application_with_IAR

Thanks,

Keegan

Keegan,

Hello!!

I still try to send packet by tcp, and I find my problem!

connect function return -1, it look like something wrong.

Could you help me check my code?

send function is correct. It return 9 bytes.

ulCC3000DHCP = 0;
ulCC3000Connected = 0;
ulSocket = 0;
ulSmartConfigFinished=0;

WDTCTL = WDTPW + WDTHOLD;
sockaddr saddrClient;
initDriver();

while (1)
{
__bis_SR_register(LPM2_bits + GIE);
__no_operation();

hci_unsolicited_event_handler();

char buf[9];
strcpy(buf,"@@");
strcat(buf,"id");

saddrClient.sa_family = AF_INET;

saddrClient.sa_data[0] = 0x0;
saddrClient.sa_data[1] = 0x45;
saddrClient.sa_data[2] = 0xc0;
saddrClient.sa_data[3] = 0xa8;
saddrClient.sa_data[4] = 0;
saddrClient.sa_data[5] = 0x64;

ulSocket = socket(AF_INET,SOCK_STREAM,IPPROTO_TCP);
h=connect(ulSocket, &saddrClient, sizeof(saddrClient));
__delay_cycles(100000);
r=send(ulSocket, buf, 9, 0);
__delay_cycles(100000);
closesocket(ulSocket);
ulSocket = 0xFFFFFFFF;

}

By the way, I updated firmware v1.10.2 and latest CC3000HostDriver and CC3000SPI code.

I also finished StartSmartConfig.

Many thanks!

Keegan,

I have the other problem!

Connect() function is not stable.

Connect() function sometimes fail, so my code will hang up in Connect() function.

Is "__delay_cycles" any problems?

while (1)
{
__bis_SR_register(LPM2_bits + GIE);
__no_operation();

hci_unsolicited_event_handler();

char buf[9];
strcpy(buf,"@@");
strcat(buf,"id");

saddrClient.sa_family = AF_INET;

saddrClient.sa_data[0] = 0x0;
saddrClient.sa_data[1] = 0x45;
saddrClient.sa_data[2] = 0xc0;
saddrClient.sa_data[3] = 0xa8;
saddrClient.sa_data[4] = 0;
saddrClient.sa_data[5] = 0x64;

}
