[error]Esp8266 bcn_timeout and reset

[Heiz]

hello anyone,

I run with esp8266 base on RTOS_SDK_1.5.0,I try to work with Station mode，and send udp single packet every 2S.
Then something erro happened! the error log show in my UART0:"bcn_timeout,ap_probe_send_start" .,and my esp_board reset without any fault.

Is any one has solution to fix the problem?

Can you share the log after the reboot? It might be a watchdog reset.
By the way, if you send data out every few seconds, please use the RTOS delay function, do not use a loop delay or occupy CPU for too long to create delay. That will cause random resets.

Hi pratik,
the error log shows below.
I use os_timer_setfn()API to make the timer every 2S,i think it will not block the cpu too long,doesn't it?

You can use the os_timer functions for any amount of time, even thousands of seconds. But note that FreeRTOS API has specific programming techniques for creating tasks that execute in intervals. You should use that, do consult the FreeRTOS API guide for reference.
It is important that you do not starve the idle task of time.
The os_timer APIs are great for use in nonOS SDK, but not required in FreeRTOS really.

If you are trying form Adminstrator window, try to chagne the defalut Timeout settings available.
