![]() # - Send command to controller to differ between flashing and transmitting SPIFFS image. # use it like: python espota.py -i -I -p -P -f # This script will push an OTA update to the ESP # Modified since from Matthew O'Gorman () I’m not sure why the timeout would configurable… as going by the espota.py script, it is hard coded for 10 seconds, and doesn’t have a ‘timeout’ option… quite strange! Maybe platformio is running it multiple times? esp8266/Arduino/blob/master/tools/espota.py?utm_source=platformio&utm_medium=docs #!/usr/bin/env python I’d probably be tempted to increase the lookup to at least 5 seconds, so 50… I’ll have a look at the code I did to do something similar… basically all in setup instead of loop. Is my look of 30x 100ms enough to catch the OTA (the while loop with ota handle() ). In platformio.ini " upload_flags = -timeout=20" it looks like the unit for this flag is 10sec ? curious, no? It does not always works and I wonder the following: So I launch an upload from atom and just wait… I do not have any “loop()” fonction, like most code with deepsleep, so I set a short loop at the end of my code, this way: mqtt.disconnect() ĪrduinoOTA.begin() // initialisation de l'OTA I added some OTA handling at the end of my code, before going back to sleep. I currently work on a weather sensor that spend most of its time in deepsleep, shortly wake up, measure and send data and goes back to deepsleep. Wake stub code must be resident in RTC Fast Memory.I use atom+platformio to develop some software on ESP8266. It is only necessary if you want to have special behavior immediately on wake. It is not necessary to implement esp_wake_deep_sleep() in your app in order to use deep sleep. If supplying a custom wake stub, the first thing it does should be to call the predefined esp_default_wake_deep_sleep() function. There is a default version of this function provided in ESP-IDF, but the default function is weak-linked so if your app contains a function named esp_wake_deep_sleep() then this will override the default. This function runs whenever the SoC wakes from deep sleep. The wake stub in ESP-IDF is called esp_wake_deep_sleep(). RTC memory regions hold their contents during deep sleep. ![]() After the wake stub runs, the SoC can go back to sleep or continue to start ESP-IDF normally.ĭeep sleep wake stub code is loaded into “RTC Fast Memory” and any data which it uses must also be loaded into RTC memory. This function runs immediately as soon as the chip wakes up - before any normal initialisation, bootloader, or ESP-IDF code has run. This possibility is rarely discussed, but is nevertheless documented by Espressif.ĮSP32 supports running a “deep sleep wake stub” when coming out of deep sleep. Now I would just like to draw your attention to an additional possibility concerning the waking phase after a deep sleep. - // Initialization // - // forward declaration void flashActiveLED () void setup () To Go One Step Further So, if you want to use the data over reboot, store it into the RTC memory by defining a global variable with RTC_DATA_ATTR attribute: And in the same way, we need to store the ledIndex value in the RTC memory to preserve it during deep sleep. That’s the reason, for example, the chip stores Wi-Fi and Bluetooth connection data in RTC memory before disabling them. So, its content is preserved during deep sleep and can be retrieved after we wake the chip up. However, the RTC memory is kept powered on. The current value of ledIndex, which is stored in RAM, was not retained after the sleep phase. This is the reason why, after waking up, the active LED is that of index 0 (the red LED), regardless of the ledIndex value before going into deep sleep. So, everything stored in that memory is wiped out and cannot be accessed. This sleep pattern is known as ULP sensor-monitored pattern.Īlong with the CPU, the main memory of the chip is also disabled. What the hell happened? You don’t get the same behavior at all as after a light sleep.ĭuring deep sleep mode, the main CPU is powered down, while the ULP coprocessor remains receptive to the timers or can perform sensor measurements and wakes up the main system when a timer is triggered, or based on the data measured by the sensors. ![]() The active LED stops flashing immediately after waking up.When the ESP32 wakes up, the active LED is always the first LED of the ramp.Your browser does not support the video tag.
