Re: ESP Touch smart config不成功

今天开发板使用non-os sc 2.4和2.5.1, ipad iOS 9.0,直接运行EspTouch,成功。 再次安装EspTouch到ipad或者iphone6,运行就不成功了。开发板输出: T|once 1 80 20:0c:c8:06:f3:c1: 594 20:0c:c8:06:f3:c1: 593 20:0c:c8:06:f3:c1: 592 20:0c:c8:06:f3:c1: 595 T|once 2 80 save, rssi:-74 20:0c:c8:06:f3:c1: 20:0c:c8:06:f3:c1: 593 20:0c:c8:06:f3:c1: 592 20:...

Re: SmartConfig: takes long time in SC_STATUS_LINK state

Hi Espressif, I am using SDK 1.4 and latest Espressif _EspTouch Android app. During smart config process the channel is found immediately as soon as I press "Confirm" on APP, however the ESP firmware takes long time (20-25 Sec) to reach SC_STATUS_LINK state. Sometimes I have to re-start b...

Re: Smartconfig error: F|SCAN CRC SSID: 0

When I use ESPTouch(V0.3.4.3) to smart config ESP8266(SDK version: v1.4.0), strange error posts up, here is the detail message: TYPE: ESPTOUCH F|sniffer on ch:1 F|rssi:-45, ch:1 F|head:82 F|0-12 F|4-14 F|6-15 F|all lenth: 23,pswd lenth: 8 F|SCAN CRC SSID: 0 F|232-3 F|180-4 F|192-5 F|168-6 F|11-7 F|...

Re: Wake up times for system_deep_sleep_set_option()

Does Espressif (or anyone else) have the wake up times for the various options for system_deep_sleep_set_option()? ⋅ Radio calibration after deep sleep wake up ⋅ No radio calibration after deep sleep wake up ⋅ Disable RF after deep sleep wake up hi,the factors of time ...

Re: 关于休眠功耗的处理

1、Modem-sleep 仅在 Station 模式下,连接路由器后生效。 ESP8266 通过 Wi-Fi 的 DTIM Beacon 机制与路由器保持连接。在 Modem-sleep 模式下, ESP8266 会在两次 DTIM Beacon 间隔时间内,关闭 Wi-Fi 模块电路,达到省电效果,在下次 Beacon 到来前自动唤醒。睡眠时间由路由器的 DTIM Beacon 时间决定。睡眠同时可以保持与路由器的 WiFi 连接。 API wifi_set_sleep_type(MODEM_SLEEP_T) 2、Light-sleep 的工作模式与 Modem-sleep 相似,不同的是...

Re: 关于休眠功耗的处理

我们想得到平均电流小于1mA的工作功耗:使用light sleep模式下测试发现电流还是有几mA,官方的资料上显示能达到0.9mA左右,于是我们有一些疑问: 1 官方的测试系统是否外置了FLASH芯片?还是单个ESP8266测试。意思是官方的0.9mA是否是带有外置flash芯片的系统电流? 2 在网络连接不断掉的情况下,是否有更好的方式使工作电流小于1mA?不改变其他设备的设置的情况下。 3 把sdk的大部分程序块放入ESP8266中,也就是不用ICACHE_FLASH_ATTR的命令,是否能达到省电的目的? 现在有一个项目在这个方面很纠结,希望得到一些支持,不胜感谢!! 您好, 1、单芯...

Re: Power consumption problem when the AP is not avaliable

(I tried to post in this thread a couple of days ago, apparently my comment was not approved by the moderators. I'll try one more time...) I have encountered the same unexpected behaviour of the chip. I think we need to distinguish between two scenarios here: (A) The ESP involuntarily loses connect...

Re: Deep sleep option 4 - RF works/current consumption is normal after wake up

hey, I connected GPIO16 to RST and wrote a simple program that sends data over WiFi. I am using Arduino IDE so I tried the API calls in the package. I tried: ⋅  ESP.deepSleep(10*1000000, RF_DISABLED); ⋅  ESP.deepSleep(10*1000000, WAKE_RF_DISABLED); ... and it didn't work. Power ...
