Uploading example "level 1 Ninja basic" from Otto Blockly to my Otto Ninja gives this Error: Command failed: arduino-cli.exe upload --port COM17 --fqbn esp8266:esp8266:nodemcuv2 sketch/sketch.ino Traceback (most recent call last): File "D:\Software\OttoBlockly\compilation\arduino\packages\esp8266\hardware\esp8266\2.7.4/tools/", line 65, in esptool.main(cmdline) File "D:/Software/OttoBlockly/compilation/arduino/packages/esp8266/hardware/esp8266/2.7.4/tools/esptool\", line 2890, in main esp.connect(args.before) File "D:/Software/OttoBlockly/compilation/arduino/packages/esp8266/hardware/esp8266/2.7.4/tools/esptool\", line 483, in connect raise FatalError('Failed to connect to %s: %s' % (self.CHIP_NAME, last_error)) esptool.FatalError: Failed to connect to ESP8266: Timed out waiting for packet header Error during Upload: uploading error: uploading error: exit status 1. What do I wrong? I have CH341 driver installed and device manager shows USB-Serial CH341 (COM17). Should I use the RESET and FLASH buttons to upload the Otto Blockly sketch?
