The Wemos D1 Mini is a small and inexpensive development board based on the ESP8266 Wi-Fi module. It is designed to be easy to use and ideal for Internet of Things (IoT) projects. The Wemos D1 Mini features a powerful microcontroller that allows you to connect your project to a Wi-Fi network and interact with various sensors and modules.
The Status LED on the Wemos board just blinks and there is no steady LED on light. SO i tried to flash the Wemos again with the same result. No permanent Status LED -> No SSID ONstep available. SO i did purchase 2 additional Wemos D1 mini pro because i assumed it might be a hardware problem. Even with the new boards the samle problem.
Connect the D1 MINI with your USB port; Then go to Tools, and ensure that the Lolin (Wemos) D1 Mini board is selected; Then go to Tools, Port, and select the USB connection to your D1 Mini. Important if the USB connection does not show up it indicates that your cable might not provide the Data capabilities. Then please change to another cable.
Step 3 – Setting Up the UDP Listener on Wemos D1 Mini. Now all you have to do is setup a listener on the Wemos. Download the sketch from the link below. Download. Code Explained const char* ssid = "rootsaid"; const char* password = "testpassword"; This is where you enter the ESSID and Passphrase of your network.
The devices is a WeMos D1 Mini for Slave and a NodeMCU for Master. I use SimpleModbusMasterV2 and SimpleModbusSlaveV10.The c… Hi, I have a project in making a Master-Slave Modbus Communication with RS485 using ArduinoIDE.
Im having a simular problem. My D1 Mini also does not boot when data is connected to D4. It works find when disconnection D4 and then reconnecting once its booted. I have no resistors or level shifters in my circuit at all. I suspect it has to do with the D4 being pulled low on boot which is supposed to be high ( reference).

This is D1 mini, it is a mini NodeMcu Lua WiFi board based on ESP-8266EX. D1 Mini NodeMcu Lua 4M Bytes WLAN WiFi Internet Development Board Base on ESP8266 ESP-12F for Arduino, Compatible with WeMos D1 Mini. 11 digital input / output pins, all pins with interrupt / PWM / I2C / support 1 line (except D0); 1 analog input(3.2V max input).
Development Board¶. The board we are using is called “WeMos D1 Mini” and has an ESP8266 module on it, which we will be programming. It comes with the latest version of MicroPython already setup on it, together with all the drivers we are going to use.
