Hello Jason Tao,

I'll start with the second question:

@2 can you run hello world which is published on cc3000 cookbook page? I updated 12 days ago all of my repositories, with improved API. Please use the newest version. http://mbed.org/users/Kojto/code/cc3000_hello_world_demo/

@1 Frank published the mbed version of patch programmer (which is currently offline), with modified user info. I think you have not run it on your cc3000 board, thus just ignore those readings. Did you use any patch programmer for cc3000? How can arduino report version 1.24? CAn you direct me to the page with a code. I would like to check it.

Let us know.

Regards,

Hi Martin, @1 I am trying it right now.

@2 I didn't actually use the patch programmer. The patch programmer for arduino (https://github.com/cmagagna/CC3000Patch) has the functionality to check the existing service pack version. When I check the version, it showed that the version 1.24, and I think it indicates the cc3000 I am using has the newest firmware. Correct me if I am wrong.

Thanks a lot for the help!

Jason

Hi Martin,

I tried to use the newest version but didn't make it work.

"cc3000 Hello World demo.

...

Failed to connect. Please verify connection details and try again. "

Are there some steps missing here? Here is what I did after importing the program (http://mbed.org/users/Kojto/code/cc3000_hello_world_demo/):

1. @main.cpp, line 30, I changed the ssid. Since my network does not have password, I set "" for phrase and set sesecurity to be NONE:

"#elif (MY_BOARD == MBED_BOARD_EXAMPLE)

cc3000 wifi(p9, p10, p8, SPI(p5, p6, p7), "my_network", "", NONE, false);"

2. @main.h, line 24, I set MY_BOARD to be MBED_BOARD_EXAMPLE, since I am using LPC1768:

"#define MY_BOARD MBED_BOARD_EXAMPLE"

3. @NVIC_set_all_priorities.h, I defined LPC176X because I am using LPC1768:

"#define LPC176X"

It seems the program stuck at connect_open(_ssid) in cc3000.m.

When I look into the code, the program did not run "connect_secure(_ssid,_phrase, _sec)" because the phrase is less than 8 characters (my passphrase is empty, i.e., "" ):

"if (strlen((const char *)_phrase) < 8) {

std::printf("password is shorter than 8 digits?\r\n");

if (connect_open(_ssid)) {

break;

}

}"

Then the question comes to that why the connect_open(_ssid) does not work?

Try to expand timeout for connecting. I will test connect_open tonight, will report the outcome here.

How are you powering the CC3000, whille transmitting it can require a lot of power, the mbed alone might not be able to power it and you may need an external supply. Or it's an issue with connecting to an open access point, can you try a secured one?

Hi Martin, I will increase the timeout and try it out.

Hi Carl, I use the current source to power up the cc3000, which should be able to provide the necessary voltage and current. Currently, the voltage supply is 5V and the running current is 125mA.

Hi Carl, I cannot try the secured connection now but will try the secured connection when I get home. Thanks for pointing it out.

I have tested cc3000 on Wi-Go board, unsecured connection. Working.

Hi Martin, thank you very much! So since you have tested the unsecured network, it narrows down the problem to hardware setup, firmware for cc3000 and configuring the code. BTW, when you check the patch programmer for arduino, did you notice anything not correct?

I am little bit lost what should be the next step to solve this problem, so here I am just listing the things in my mind now:

As for the hardware setup for spi, I followed:

"cc3000 wifi(p9, p10, p8, SPI(p5, p6, p7)"

where p9 = irq, p10 = bat, p8 = cs, p5 = mosi, p6 = miso, p7 = sck. I think the hardware configuration for spi should be correct, because I can see from the debug line that cc3000 confirms that it receives the cmd with the right opcode.

As for cc3000 firmware, I may give it a shot some time today. Last time I saw the version is 1.24 so I didn't proceed since to a newbie like me it is kinda scary to do it: according to the website (https://github.com/cmagagna/CC3000Patch), there are chances I will make cc3000 a piece of useless metal.

As for configuring the code, am I doing it correct by setting MY_BOARD, defining LPC176X and updating the ssid, passphrase and security? Is there anything else I need to do?

I will post what I get today.

Hi Martin, I just noticed that you tested cc3000 with Wi-Go board. Has anyone successfully setup cc3000 with LPC1768 using unsecured network in your knowledge?

David Fletcher, who helped you previously. I have also external cc3000 and mbed board. I can set it up and run today/tomorrow.

To answer your question , yes, set your board, your cc3000 configuration (cc3000 object) and set your ssid details, that should be all you need to do.

Thank you Martin! Due to the course load, I shift my project on cc3000 to tomorrow. I will post on my progress tomorrow.

Hey Jason, have you successfully got it working? It's been a long time but I hope you can post some updates. Thanks!
