Huzzah Feather (ESP8266) Wifi Module

by bdoan on Wed Apr 20, 2016 1:55 pm

On connection to USB (or after reset) I get a flash of the blue, yellow and red LEDs (several flashes on red)

On opening terminal program (9600 8-1-N) I get

0▒~?▒4▒!▒Y▒OI:▒COCE▒!▒▒OCA▒H▒
NodeMCU 0.9.5 build 20150318 powered by Lua 5.1.4
lua: cannot open init.lua
>

After that, I cannot get any response from the unit when typing commands.

What terminal program are you using? Have you turned off any sort of flow control or handshaking?

I am using Terminal.exe (95 version)

No flow control

Same results with PuTTY

I scoped the TX and RX lines from the ESP8266 to the USB converter and I see no RX data
