Re: "malloc assert!" in interrupt routine

Do you use push button? It will cause too many interrupts, and user_procTaskQueueLen is limited, so system_os_post will not be able to post all events to your task. Then os_free will not be called in your loop function, 'malloc assert' happened. I modify your iw_GPIO_handler, as follow: // GPIO inte...

Re: Some power saving questions

@Espressif_Faye: Deep sleep is a great feature that enables battery applications. This is particularly helpful when sensor data is transferred with long time interval like 10 minutes. But how can we reduce regular power consumption when NOT in deep sleep? For applications that need to check switche...

Re: Stopping bootloader output

bootload is in ROM, we cannot change to use UART1.
There is a topic similar with yours, you can check whether the answer from costaud is useful.

Re: Linking against RTOS SDK.

Do you add -lc in your Makefile?
If yes, please delete it, don't use libc.a in RTOS SDK.
We have ported some frequently-used libc apis in SDK, you can refer to include/espressif/esp_libc.h.

Re: wifi_station_connect() api call behavior in esp_iot_rtos

hi,jmg5150 A1: We will support this feature later. Some events will be post to user side, such as CONNECT, DISCONNECT, SCAN_DONE etc., so you can handler what you want by yourself. A2: Esp8266 has two UART, UART0 is used to output log by default, but you can change to use UART1 by using os_install_p...
