ESP8266 "calling home"
use in Wireshark. My device is an ESP8266 coupled with an I2C BH1750 light sensor. The ESP8266 contains portions of the „ESP8266AdvancedWebserver“ example of the Aruino IDE (1.6.4) plugin, which was installed through the board-manager.
to check if your ESP8266 is calling home as well. You just need to check the routing table of your router. Please post if your ESP8266 connects to "alien" servers as well. Positive/negative reports are welcome. I

ESP8266 RGB LED Strip Controller
which is already being developed in my free time. For the WiFi module I want to use the infamous ESP8266 board, namely an ESP-07 (http://www.banggood.com/ESP8266-ESP-07-Remote-Serial-Port-WIFI-Transceiver-Wireless-Module-p-968191.html). The plan is to flash it with nodemcu (http://nodemcu.com/index_en.html

From what I know, I should choose a FET that can be switched fast (requirement for PWM) and has a maximum gate threshold voltage below 3.3 Volts. Based on these requirements and the availability

NodmCU ESP8266 not to flash
I have tried everything under different operating systems and with various USB cables. I even bought a super-short USB data cable especially for this purpose. The error message reads: ‘Failed to connect to Espressif device: Timeout waiting for packet header’. Pressing the boot or rst button did not help either. I am completely at a loss. Even the trick with the 10 my Elko was unsuccessful.

Problems with ESP8266, IRF510N and circuitboards
Good evening. I encountered some problems during my Project with the ESP 8266 in combination with the IRF510N on a circuit board. I wanted to build an RGB controller for common anode RGB LED strips. The project and the code are done, and I tested the whole project on my
ESP module operates on. The more important test was to check whether there is a voltage drop between the GND pin of your ESP8266 and the source pins of your transistors. You did not answer this question

Reverse phase control / trailing edge dimmer with Arduino / ESP8266
I want to build a trailing edge control / reverse phase control dimmer controlled by Arduino or ESP8266.

PCB w/ ESP8266 NodeMCU - Multiple SPI modules not working
Hello, I've been working on a project for quite a while now, which involves the ESP8266 NodeMCU (v1.0), as well as two SPI Modules: ENC28J60, and RFID-RC522. With that being said, I encountered a problem recently, which I haven't been able to resolve so far. Working with micro-controllers
Hey T, thanks for the reply. yes, the SDA_RFID pin is the D0 pin on the ESP, which is configured as an output pin. It is passed to the RFID-lib I am using (called MFRC522) as slave-select. best regards, Ed

How to adjust WiFi-channel for ESP-NOW
wie der der mit dem WiFi-Router verwendet wird. Ich habe aber nichts darüber gefunden wie man bei ESP-NOW fr ESP8266 den Kanal einstellt. Bei ESP32 wird eine andere Library benutzt. Deswegen kann man die Erkenntnisse von ESP32 nicht auf ESP8266 übertragen. Jedenfalls nicht alle. Weiß jemand wie man bei ESP8266 den ESP-NOW-Kanal einstellen kann? viele Grüße Stefan

ATmega328 + ESP-01s low power brainstorm
outside of these hours. \*\*\* I suppose an even better approach would be to use a variant of the ESP8266 that has more pins available but I already have three ESP-01s so I'd like to stick with them now.
first step to save power is to reduce the chip count. Reading the sensor can be done with an ESP8266, so you can save the arduino board completely. Deep sleep the ESP8266 https://www.esp8266.com/wiki/doku.php?id=esp8266_power_usage and you achieved your goal.

ESP-07 AT commands not working, programming works though

One more think to check: The ESP-07 modules do not have a capactor at the reset pin, and also no pull-up resistor. See the schematics details on http://stefanfrings.de/esp8266/index.html#esp12 Can you start them by issuing an

OpenHR20: Firmware for Honeywell Rondostat HR20E
using OpenHR20 firmware quite a while now and I'm very happy with it. Some time ago I found those ESP8266 low cost WiFi modules which just need an serial interface. The protocol is quite easy (some AT commands for configuring and a few for UDP- or TCP-connections). Would it be possible to modify OpenHR20
ESP8266 is nice chip/module It will work, HR20 have serial line in connector. But don't expect life time longer than days with batteries. This module is little bit hungry compare to RFM12 :-)
