It WORKS finally!! It took multiple tries of the button dance but finally it actually worked!! Right at the [Connecting........_] I let go of the EN button: Ralph@HP_10292012 MINGW32 ~/esp $ cd hello_world Ralph@HP_10292012 MINGW32 ~/esp/hello_world $ make flash Toolchain path: /opt/xtensa-esp32-elf...

I am running the EXPRESSIF Getting Started Code how would I skip the LUA part? ...

I got Putty running and see the same LUA error! in Putty!

load lib: utils
load lib: lpeg
load lib: net
load lib: thread
load lib: mqtt
load lib: nvs
other libs:
lua: cannot open init.lua
stdin:1: unexpected symbol near ':'

I also cannot Open a Putty session!

If I try to run : make monitor I get: load lib: file load lib: tmr load lib: i2c load lib: uart load lib: utils load lib: lpeg load lib: net load lib: thread load lib: mqtt load lib: nvs other libs: lua: cannot open init.lua Is there anything I need to do or can do? Thanks for the help, Ralph

Thanks for the help!!
