Wi-Fi Combo Forum Discussions
Interesting observation.
We have a WICED development board configured to connect to an AP with DHCP. Before network up, app registers for link and ip change events. After successful connection, the application stays idle. The AP is D-Link DAP-1350.
After an hour or so being idle, it keeps cycling periodically from link down, ip change, link up, ip change states. It keeps cycling until it stops getting the ip change and stops. No other device on this AP is experiencing this behavior, as far as we can tell.
Any suggestion is appreciated.
Show LessWe are getting spontaneously disconnected from the AP. I saw another thread that suggested enabling the keep alive option to resolve this. Regardless of any fix, I would like to know what some of the errnos we are seeing mean. These are all seen when trying to send using lwip_send.
1. #define EINPROGRESS 115 /* Operation now in progress */
What does operation in progress mean? What operation?
2. #define EAGAIN 11 /* Try again */
This one is pretty self evident, and I understand that the message should be resent, but does anyone know why I would see this?
3. #define EIO 5 /* I/O error */
IO error I get, but at which layer? Is it caused by the SDIO connection between the host processor and the BCM433262 or is it an IO error at the wifi level?
Show LessWe are running a BCM43362 in conjunction with an STM32F415. We are seeing an issue with roaming. Every 2 to 8 roams causes the system to no longer be able to connect to the AP. This is experienced with "wiced_wifi_scan" failing to return with WICED_SUCCESS. Sometimes the system, fails to jump to another ap and we can no longer send with no deauth being reported by the link_handler. Other times the roam succeeds, but soon after the system fails to send with a deauth also never being reported. When this occurs, "host_buffer_get" seems to always be failing on "pbuf_alloc".
The memory used for wiced and lwip buffers has a large number of fragments but still has a lot of space. Once we get into this state, the only recovery is a system restart.
Has anyone also experienced this?
Our process for roaming is fairly simple. We have the link_handler subscribed to the roamed event, which alerts us that a roam occured. When this happens, we renew the DHCP lease but don't wait for it to complete. Other than that, we don't stop any sockets or prevent them from send/receiving.
EDIT: we are also not receiving the link events for WLC_E_ROAM_START. This along with WLC_E_ROAM_PREP would be useful to manage our low power scheme, but even though they are added to the link_events list, they never seem to be reported by the platform. WLC_E_ROAM does get posted after a roam completes.

Show LessHi,
I have a customized board with 43362,
and try porting WICED driver to ourself micro kernel with LWIP.
when program run wiced_management_wifi_on,
It is success when setting "sta" and "bus:txglom",
but setting "country", it return timeout.
wifi chip seems no response when set "country".
any suggestion for me?
thanks

Show LessOn compiling the Test Console App I get the following message:
Making test_console-TWRK60D100M.elf

What is the procedure within the WICED SDK for compiler optimization to optimize the code for size? (to create more compact code?)
Thanks!

Show LessHi,

Show LessHi Jason,
As you said before, the 43362 softAP supports 5 clients.
If customers wants to limit the maximum number of clients, then what should be changed in SDK 2.2.1?
thank you,

Show LessHi,
I am trying to compile wiced source code and gets following error message all the time
**** Build of configuration Default for project WICED-SDK ****
(Cannot run program "\make.exe": Launching failed)
Anyone have experienced same problem ? How can I solve this
Thanks

Show LessHi,
Since OpenOCD supports XDS100V2, it seems that it should be possible to use XDS100V2 (from TI) with WICED EVB. Has anyone had any experience in doing so?
