While working on a wireless project, WiFi range is a common issue. Today We have experimented with WeMos D1 Mini by replacing ESP-12F with ESP-07 with external antenna. Here are various points one must take care of while flashing ESP-07.
Key Points:
- Change board to Generic ESP8266 module.
- Choose Flash size to 1M(64K SPIFFS) otherwise OTA will not work.
- Choose Reset Method to “nodemcu” otherwise uploading will not working on WeMos D1 Mini ESP-07 modification.
FYI, esp-07 is an esp8266, just a version with an antenna connector. (most wemos/nodemcu come with esp-12* boards on them, generally 12e or 12f)
