Re: RTC demo

The SDK REALLY needs a proper 64 bit RTC value that can be SET and read. With the likes of LUA and MQTT, it is possible to go off and get a 64 bit TIMESTAMP - we need to be able to set a value that is incremented once a second by an internal system clock - that way we will be able to get the time o...

Re: Changing GPIO inside task with GPIO interrupts bug?

Perhaps a stupid question, but you are aware of contact bounce, which in this case can very well trigger quite a few interrupts?

Re: Some power saving questions

@Sprite_tm , it seems that you have many questions about how to use our APIs, please contact sales@espressif.com to sign NDA, then you can get our documents about APIs and else. ;) I absolutely do :) I really like this device and would like to do awesome things with it; things you can only reach by...

Re: SDK 0.9.4: different espconn_sent behaviour?

Okay, then I'll have to modify esphttpd accordingly. Thanks for the response.

Re: Some power saving questions

Espressif_Faye: Thank you very much! Now all we need is an interface to load and save the WiFi parameters (channel, ssid, DHCP address etc) so we can just load those on startup and be up and running within 2 seconds. Jackon: How do you use those sleep modes? I've seen the new wifi_set_sleep_type cal...

Re: SDK 0.9.4: different espconn_sent behaviour?

Can be used like that? I was told to call next espconn_sent after espconn_sent_callback of the pre-packet.. :roll: :? All I can say is: it worked in the past. If espconn_sent can only be used once per callback, I'd like to know that so I can work around this limitation, but it would be pretty incon...

SDK 0.9.4: different espconn_sent behaviour?

Hello, In SDK 0.9.3 and earlier, if I would call espconn_sent consecutively in a function, it would sent all the data concatenated. If I do the same in 0.9.4, I only see the data from the first espconn_sent. So eg: espconn_sent(conn, (uint8 *)"Hello", 5); espconn_sent(conn, (uint8 *)"...

Re: Some power saving questions

I'm going to kick this once more, I really hope the Espressif people can give some answers; getting this to work a bit better would make the ESP way more usable as a low-power sensor thing. At the moment, I measure the ESP coming up, sending an HTTP request and going to sleep takes about 5 seconds. ...

Re: Some power saving questions

And another question: As far as I can see, a return from sleep mode now involves a complete reset, which means the device has to do a scan, associate and dhcp request in order to get the network working; I measured that to take about 5 seconds, which at 70mA average (assumed) is quite long if you ha...

Some power saving questions

I was browsing the sources for the RTOS port you guys just posted, and I saw some nice functions I have a couple of questions on: About system_rtc_mem_read and system_rtc_mem_write: I presume this is meant to store data over a reset cycle, so you can save stuff when going to deep sleep without havin...
