Wi-Fi Combo Forum Discussions

Hi,

I am using WICED Wifi BCM943362WCD4 eval board to interface with RS 485 through UART. I am using IC SP3485CP (Half duplex RS 485 Tranceiver) based circuit for communication between RS 485 bus and WICED board.

I want to use the RTS pin in WICED_UART_2 to control the direction in Tranceiver (SP3485CP). But whenever I transmit bytes from UART, I cannot see any change in the voltage level of RTS pin .

I have configured UART as shown below.

wiced_uart_config_t uart_config_meter_tx =
{
  .baud_rate    = 9600,
  .data_width   = DATA_WIDTH_8BIT,
  .parity       = EVEN_PARITY,
  .stop_bits    = STOP_BITS_1,
  .flow_control = FLOW_CONTROL_RTS,
};

wiced_uart_init( WICED_UART_2, &uart_config_meter_tx, &rx_buffer_one );

I transmit bytes using the following function.

wiced_uart_transmit_bytes( WICED_UART_2, (const char *)tx_data, 7)

The bytes are getting successfully transmitted as seen on CRO on Tx pin of UART but RTS is not seen to toggle. (As per platform.c WICED_GPIO_11 is the RTS pin which I am monitoring)

Any idea how to get this working or is RTS pin not connected in this board?

Thanks.

How can I limit the WiFi-data-rate?

I tested as below but it seems like that it didn't work well.

- WICED SDK 2.4.0

- Application : Apps/test/console

- Test Log

But when I checked the rate in the AP(which WICED-module associated to), the rate always was 65M.

What did I do wrong?

Is it a bug or something of "apps/test/console"?

Thanks in advance, Steve

Hi,

We are using BCM9WCDPLUS114 board and test.bt_smartbridge_console app

Is there any ways to retrieve the rssi value to see how close we are to the peripheral devices?

Thanks~

I've been trying to run the WiFi Direct sample application (p2p) in the WICED 2.4.0 SDK but so far without success.  After building and loading the application I am unable to discover the WICED board with my smart phone and see no probe requests when I run a wireless trace.  The console output looks like:

Platform BCM943362WCD4 initialised

Started ThreadX v5.5

Initialising NetX v5.6

Creating Packet pools

Starting Wiced v2.4.0

WWD SDIO interface initialised

WLAN MAC Address : 02:0A:F7:50:BF:8D

STA MAC: 00:00:00:00:00:00

The zero MAC address looks a bit odd, but I haven't touched anything that would affect it.  I've successfully built and run a couple of the other sample applications (scan and ap_clients_rssi) so I know the SDK is installed properly.
