Re: Minimizing power consumption while connected to WiFi Post by hassan789 » Thu Nov 23, 2017 1:35 am A good article on how modem-sleep, light-sleep and DTIM will work (but its for esp8266). The Air602 WiFi Development Board is based on the Air602 Wi-Fi module and an integrated USB interface and Antenna. The device power management in IoT involves all the steps related to the designing process and it is very important to take into account how the device will behave and how this behavior affects energy consumption. Articles sur les ESP8266 et ESP32 J'ai adoré écrire ces articles ici: - Python Flask et SQLite pour le Raspberry Pi 3 ou 4 - exemples de communication avec des ESP32 ou ESP8266 - MicroPython pour le NodeMCU (ESP8266) avec Thonny (août 2019) - PyDev, un IDE pour Python, sous Eclipse et pour le Raspberry Pi 3. 25 packet radio communication relay and PBBS, with in-session APRS beaconing, programmed in Python, C and Lua, with a capstan hoist and rocking solar tracker, using an ESP8266, Raspberry Pi Zero W, two ATtiny 1634 microcontrollers, and a Baofeng UV-5R series packet radio, with 3D-printed robotics. Wi-Fi is a popular wireless networking technology.
