Wi-Fi Combo Forum Discussions

Hello.

The web server is started after starting the softAP interface.
How can I limit the number of terminals that can be connected to the Web server to one? (Prefer the first connected terminal.)

I use bellow function:
    wiced_network_up () (WICED_AP_INTERFACE)
    wiced_http_server_start ()

Thank you.

Hello.

If a WPS connection is executed using the following functions, it will stop with an error.

Please tell me the cause and countermeasure.

Function used: wiced_wps_enrollee ()

Error stop function:

wps_result_t wps_host_join (void * workspace, wps_ap_t * ap, wwd_interface_t interface)

   {

              ~ Omitted

              ret = (wps_result_t) wwd_wifi_join_specific (& ap-> scan_result, NULL, 0, & semaphore, interface

Omitted

              if (wwd_wifi_is_ready_to_transceive (interface)! = WWD_SUCCESS)

              {

→ Error stop WPS_ERROR (("Failed to join WPS at interface% u \ r \ n", (unsigned int) interface));

Thank you.

Hi Sir,

     目前在考虑MCU+CYW20706实现headset的方案，通过wiced20706 demo.audio.headset发现有两种模式：Apps processor 以及standalone mode。

如果使用standalone mode，那么不需要外部mcu参与，20706可以通过i2s接codec进行处理；如果是Apps processor mode，那么需要通过注释掉STANDALONE_HEADSET_APP，并编译成hcd文件，通过MCU烧录到20706的ram，但是这里我有个问题，在这种模式下，codec应该接在mcu侧还是20706侧？

     带着这个疑问，我又做了以下实验，找了一块43907的EVK,一块20706的EVK。通过UART 4根线以及GND把两块板子连接起来，分别通过usb 供电。43xxxWiFi里面正好有一个Bluetooth_audio的demo，默认用的是BT_EMBED_MODE，但我不知道BT_EMBED_MODE，HOST_MODE，BT_HYBRID_MODE三种模式有什么区别。我把刚才编译好的headset-CYW920706WCDEVAL_40Mhz-rom-ram-Wiced-release.hcd转换成了c file，按要求更改并替换到对应的位置，之后把snip.bluetooth_audio烧录到43907EVK，通过log发现download FW失败，串口通讯似乎没有成功。

同时也抓了UART的波形，reset命令是有发出来，但是没有response。

排查了下，接线没有问题。所以，我不确定问题出在哪里，或者说我这么操作就是有问题的，请帮忙解答下，谢谢~

Hello

Function processing in the functions of Wiced

Please tell me the sleep function.

What we want to realize is as follows.

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

(1) The monitoring target flag is initially OFF.

(2) The function starts processing. Check the status of the monitoring target flag.

(3) Sleeps for 60 seconds if the monitoring target flag is not ON.

(4) After 60 seconds, check the monitoring target flag again.

(5) Repeat steps (2) ～ (4) until it is confirmed that the monitoring target flag is ON.

(6) If it is confirmed that the monitoring target flag is ON, the subsequent processing is performed.

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

Thank you

Hi

I use cyw43364 with wiced.

I want to use coex with third-party ble.

I want to disable SECI Coex and to enable 3 wire Coex.

below is array in wifi_nvram_image.h.

Q1. I can't find nvram.txt. So I will change below parameter. Is this right?

Q2. How should I change?

Q3. What GPIO is coex pin?

Hello

I'm having trouble with breakpoints not working as expected during debugging.

Compile, start debugging, create breakpoint, start, do these in order
Stop at "WICED / platform / MCU / STM32F4xx / peripherals / platform_gpio.c: 113". This is not correct.

Please let me know if you know a solution for debugging in the expected position.

The implementation environment is as follows.

・ Chip model: CYW43438

・ SDK: WICED-Studio-6.4

Thank you
