CC3000 firmware is not stable and buggy?

Joo Hong

Hi,

I have been working on networking code using the socket API of the CC3000. When I call send function to send data over the socket, it seems like the CC3000 never return the 1003 (HCI_EVNT_SEND) response (it only return the 4100 code).

When I use the select call to monitor the incoming data and specify the timeout to be 1 second, the CC3000 never return a status stating that there is incoming data even though I input some data to the connection. If I specify no timeout, then it does work.

I am wondering anybody has the similar issue? It is kind of frustrated.

Thanks

Hi,

The CC3000 is being used for a while and problems as you are describing are not known.
Can you please share a bit more information on your environment:
1. Example code not which is not working for you
2. System description: which host processor are you using? which development platform? which IDE?

Thanks,
Alon.S

Hi,

I am using Atmel ATSAM4 chip. The following is the code (using polling scheme to receive all the data from the CC3000 through SPI bus). And CC3000 software/firmware architure I think is not easy to use and not doing right...

#define SERVER_PORT        10003
#define INADDR_ANY        0x0
#define SOMAXCONN        1

static uns8    cc3000State;
static int listenSocket;
static int clientSocket;
static sockaddr saServer;
static sockaddr saClient;
uns8 requestBuffer[128];

void cc3000_task(void)
{
    cc3000State = CC3000_STARTUP;

Here is the terminal output. As you can see, you never see the 1003 code from the CC3000.

I have the same problem the HCI_EVNT_SEND message never seems to appear after TCP socket SEND. The only CC3000 response is HCI_EVNT_DATA_UNSOL_FREE_BUFF. For course in blocking mode the firmware hangs waiting for HCI_EVNT_SEND. Did you solve this with timeouts?

Hello, I'm having the same problem. I'm connecting to an HTTP server and calling send() to send some data to the remote server. The data is definitely sent (I'm watching it with Wireshark) but I never get an HCI_EVNT_SEND response.

Can anyone at TI give us some workaround. Is it save not waiting for the HCI_EVNT_SEND response from the CC3000 chip?

Thanks.

CC3000 firmware is not stable and buggy?
