Esp8266 deep sleep wake up

You can wake up the module at regular intervals to make measurements and publish them on a server. For example, the rising edge (the signal) of a motion detector (PIR) can be used. We’ll cover deep sleep with timer wake up and deep sleep with external wake up using the reset (RST) pin. Sleep(uS) and pass as argument sleep time in microseconds.

I need it to wake the esp up from deep sleep via RST, but then to ignore further RST activations until I programmatically send it into deep sleep again. And i have some questions about that.

I want to wakeup esp via timer. I implemented GPIO16-RST connection and this version done. But, there is something we can do about that.

I think the situation is quite similar to the above, although the PIR gives a (V HIGH) signal instead of the magnetic switch in the door sensor. If you haven’t read the previous post on the unoptimized version you probably should go back so you understand my set- up. The following scope capture shows the wake cycle after optimization. The software workflow of the waking- up from deep - sleep can be configured.

So I’ve read up on deepsleep mode and see I can wake it up from a. Power Saving with ESP82( Sleep Mode) Tutorial with some Tricks.

To be able to implement deep sleep (without adding extra hardware to generate a wake - up signal), you need to link pins on the ESP8as. I made my indoor plant a soil moisture meter which reports the values to Azure cloud. However, I had some trouble making my Dmini board to sleep and wake up reliably. I had to deep - sleep for several shorter cycles before reporting the measurement.

Check out the article for a brief how-to. The overall average current is less than 1mA. V the current requirement is only μA. You need to connect GPIO-with the RST pin to make this work. What Sleep mode does when waking up : Make one connection attempt to SSI and to SSIDif its defined.

WiFi and higher level protocol connections gracefully. Make sure esp_wifi_stop are called to close any connections and deinitialize the peripherals. ESP to deep sleep and wake up with radio enabled: WiFi. Some GPIO go HIGH, some LOW, some FOLLOW the relay but work only on FET.

To do that, we are going to use the deep sleep functions of the chip, that will simply sleep when no actions are required. As a simple example, we are going to log a simple dummy message to Dweet. To enable the deep - sleep mode you only have to use the following line of code: ESP.

The maximum time in deep - sleep is 29962µs, which is about ~minutes. Note: The init parameter is the parameter value in esp_init_data_default. The only thing that is still on is RTC.

Since everything is off, this is the most power efficient option. In other words, in deep sleep mode, the device doesn’t do anything except for counting up till the wake up call. Wake up and gather all the data from the various sensors (once every minutes, takes about seconds).

Turn on and configure the radio about 1. DHCP takes about 1. Deep Sleep, WAKE_RF_DISABLED 2. Finish data acquisition 5. Burst transmit data to HTTP server. In deep sleep mode, ESP module takes only a few microamps.
