Re: Receive http data larther than 800 byte will cause reboot.

I'm using SDK 1.4 and have HTTP POST handlers that receive ~300KB requests, so it's definitely possible. You should look at some sample projects, such as esp-httpd for how to do it...

Re: How does SDK1.4 determine flash size?

Mhh, that wasn't my question, I know that.
My question is where does the SDK get the flash map from ? Is it from the header in the boot sector?

[SOLVED]How does SDK1.4 determine flash size?

I am trying to build firmware that will work with any flash size from 512KB to 4MB and one of the key items is how does the SDK determine the flash size for the purpose of placing the "system param" flash area? I know that the flash size is stored in two places: in the header of the bootlo...

Re: Why is RTC timer lost during deep sleep?

Thanks for the note about the reset reason, it is fixed in 1.4!

The fact that the RTC clock is reset is still a puzzle.

Re: Why is RTC timer lost during deep sleep?

By the way, is it expected that after a deep sleep system_get_rst_info->reason == REASON_EXT_SYS_RST and not REASON_DEEP_SLEEP_AWAKE ?

Why is RTC timer lost during deep sleep?

Is it a design feature that the RTC timer is lost during deep sleep? I observe the following (using SDK 1.3): The chip is awakened from deep sleep after a timer expiration using a gpio16->ext_rst connection The RTC memory (system_rtc_mem_read/write) is preserved during deep sleep The RTC clock must ...

Re: Wifi event callback bug in SDK 1.4

provide an official way to register an idle handler that gets invoked whenever the system is idle. That would be nice. On the other hand, I am never in this situation because when all work is done, I just return to the system, and that's, imho, how it's supposed to work. Eriksl, I'm with you on the...

Wifi event callback bug in SDK 1.4

The task priority used for the wifi event callback (invoked via wifi_set_event_handler_cb) changed between SDK 1.3 and SDK 1.4 causing "idle/polling loops" used in the javascript on esp8266 Espruino project and in the Arduino on esp8266 project not to work anymore. The idle/polling loop fu...

Re: are you improving forced light sleep?

LIGHT_SLEEP mode already uses DTIM. There are two problems with light_sleep: one is that the DTIM interval is too short. Typical values are 1 (=100ms) and 3 (300ms). The bigger issue is that the client is told about traffic which in many uses-cases is not desired. All broadcasts plus other requests,...
