You can use your web browser to go to and upload the *.bin file. That will compile a *.bin file in the same directory as your *.ino. Get started with Arduino D1/D1 mini series Get started with Arduino D32 series Get started with Arduino S2 series Get started with Arduino C3 series Get started with Arduino S3 series CircuitPython Tutorials. ![]() Next, compile it in Arduino IDE using CTRL+ALT+S. Get started with MicroPython W600 series Build MicroPython for ESP32. If you don’t do this, the firmware will not work on the Wemos. The settings will be saved across reboots.įor OTA, in Arduino IDE, click Tools -> Flash Size -> 4M (1M SPIFFS). You can then connect to the AP to setup Wifi on the Wemos. The code below uses WifiManager, which starts the Wemos as an AP if it can’t connect to a Wifi network. After the firmware is on there, you can do the updates Over-The-Air (OTA). The first time you upload the firmware, you will need to do it via serial using a USB cable. You will need to edit the custom parameters section as needed.
