noticed that PL2303-based cables don't work on Macs for some reason. FTDI or CP210x based chipsets work best

I tried that, but I'm still having difficulties uploading with the Arduino IDE

Sometimes, it helps to switch the board type to "Generic ESP8266 Module". Set the Reset Method to "nodemcu"

See this forum post

I'm stuck in bootloader mode and can't upload

You say your led is stuck on dim and you get an error trying to upload? And you're sure your serial cable is

connected and working correctly? Well, here's a potential fix: Connect the GPIO0 pin to GND through a 220 ohm

resistor. Leave it connected while you upload. You may have to try it a couple of times, but it should eventually

upload and get the HUZZAH unstuck from bootload mode! You can then remove the resistor connection, and your

HUZZAH will be happy ever after!

(Note: you may also have to tie RST and EN (CH_PD) together to get this to work. Remove the connection once you

have the module programmed).

Thanks to forum user misslevania for the tip!

I can't get Lua to respond to my commands

Make sure your terminal software is sending correct line endings! The default PuTTY settings may be wrong when

trying to talk to Lua on an ESP8266. Lua expects CRLF "\r\n" line endings, and apparently PuTTY defaults to just LF

"\n"!
