Hi.

I am trying to download a 24KB file in 4KB chunks with http_get?

Unfortunately, the way wiced_http_get is written, even though the buffer and buffer length passed into this function are less, it just gets overwritten without any notification to the user?

On line 96, we copy the data into the buffer passed by the caller of this function. How is the user notified in the next iteration of the do..while loop?

52 wiced_result_t wiced_http_get( wiced_ip_address_t* address, const char* query, void* buffer, uint32_t buffer_length )

53 {

54     wiced_tcp_socket_t socket;

55     wiced_packet_t*    reply_packet;

56     wiced_result_t     result = WICED_ERROR;

57     wiced_result_t     rx_result;

58     char *             buffer_ptr = (char*) buffer;

59

60     if ( ( result = wiced_tcp_create_socket( &socket, WICED_STA_INTERFACE ) ) != WICED_SUCCESS )

61     {

62         return result;

63     }

64     result = wiced_tcp_connect( &socket, address, 80, 10000 );

65     if ( result != WICED_SUCCESS )

66     {

67         wiced_tcp_delete_socket( &socket );

68         return ( result );

69     }

70

71     if ( ( result = wiced_tcp_send_buffer( &socket, query, (uint16_t) strlen( query ) ) != WICED_SUCCESS ) )

72     {

73         wiced_tcp_disconnect( &socket );

74         wiced_tcp_delete_socket( &socket );

75         return ( result );

76     }

77

78     WPRINT_LIB_INFO( ("waiting for HTTP reply\n") );

79

80     do

81     {

82         rx_result = wiced_tcp_receive( &socket, &reply_packet, 5000 );

83         if ( rx_result == WICED_SUCCESS )

84         {

85             uint8_t* data;

86             uint16_t data_length;

87             uint16_t available;

88             uint32_t data_to_copy;

89

90             /* Record the fact we received a reply of some kind */

91             result = WICED_SUCCESS;

92

93             /* Copy data into provided buffer */

94             wiced_packet_get_data( reply_packet, 0, &data, &data_length, &available );

95             data_to_copy = MIN(data_length, buffer_length);

96             memcpy( buffer_ptr, data, data_to_copy );

97             buffer_ptr    += data_to_copy;

98             buffer_length -= data_to_copy;

99             wiced_packet_delete( reply_packet );

100         }

101     } while ( rx_result == WICED_SUCCESS );

102

103     wiced_tcp_disconnect( &socket );

104     wiced_tcp_delete_socket( &socket );

105

106     return ( result );

107 }

Please help?

Hi everyone!

I am programming bluetooth and wi-fi apps using BCM4343W  and SDK-3.5.2

Programming works only depend on example in SDK.   not API Manual. at point of bluetooth.  (there are wifi APIs)

Where can I found bluetooth API documents in SDK-3.5.2 ?  or getting start documents ?

Apps object(goal) is that data from uart service in bluetooth transfers another internet server.(just tcp packets)

and I want to make app using bluetooth uart program using BCM4343W.  and bluetooth need to be central & peripheral.

which example in SDK is most nearly this projects ?

Thank you for reading this.

Sincerly.

When using the "wiced_dct_read_wifi_config_section ( )" to read the WiFi settings from the DCT area, and if the WiFi password contains a "0" in its string,

then the password is read incorrectly !!

example:

password = 24C51A718F --> reading it from the DCT = 24C51A718F     (good)

password = 24C50A708F --> reading it from the DCT = A1E011DD53    (not good)

so there is a bug with the read function, however, the write function is OK.

I am using Avnets BCM4343W IOT starterkit, and want to add an extra desired state to the startup example "shadow".

Broadcom/WICED provide header files to libray functions like

mqtt_connection_event_cb

parse_json_shadow_status

wiced_JSON_parser_register_callback

Wiced_mqtt_connect

wiced_mqtt_publish

but no source code unfortunately, and not enough documentation or examples for me to add an extra desired state( a local threshold variable), that I can control from

AWS iot shadow update(delta state).

How can I publish so it will register as a desired state in AWS, and how can I parse the jason document and extract the value of a specific state "threshold"?

Can I use "parse_json_shadow_status" or is it custom made for the shadow example program?

What would it take to expand the BCM4343W board to collect data from 4 sensors, send data to AWS and be able to change "threshold" to each of them?

Can BCM4343W handle 4 concurrent treads, one for each sensor?

Thanks in advance.

Hi,

I'm using lwip tcp library in my application. I am getting EAI_MEMORY: 203 error with lwip_getaddrinfo() method. The first time the method gives no error, but when used a second time at a different place in the application, it generates this error. Can you suggest a way I could correct this error? I have tried allocating suitable amount of memory using malloc. But it was of no use.

This is the memory dumped into the BCM943364WCD1. Am I exceeding memory? How much memory can it handle?

I have built, downloaded and run the snip.scan demo program.  When executed, PuTTY shows ...

Starting WICED v3.5.2

Platform BCM943362WCD4 initialised

Started ThreadX v5.6

Initialising NetX_Duo v5.7_sp2

Creating Packet pools

Waiting for scan results...

  # Type  BSSID             RSSI  Rate Chan  Security         SSID

----------------------------------------------------------------------------------------------

I get no SSID data.

I am wondering if the problem is that I have a BCM94343WWCD1 eval board.  The WICED-SDK Make Target builds are for the BCM943362WCD4 board. 

I have tried all of them and I get the same results.

Is there something I need to change to get this to work on the BCM94343WWCD1 ?

Thanks

Bill
