#69402 The easiest way I can think of:
  • Export your script to a BIN-file: "Sketch" -> "Export compiled binary"
  • Get a later version (like v3.4.4 or above) of the ESPFlashDownloadTool
  • Start the ESPFlashDownloadTool
  • Press the "ESP8266 DownloadTool"-button
  • Select the "MultiDownload"-tab
  • Load your (previously compiled) BIN-file and select the correct address
  • Make sure all available ESP's are correctly selected to their COM-port on the PC
  • Press the "START ALL"-button
  • Enjoy the ride...
Note: I haven't used this gang-programming mode myself, so above manual is all theory. :idea:
