- Sat Dec 20, 2014 10:58 am #5252 I have a handful of esp-03 modules that I have been playing around with. I got the AT commands working so next I moved onto Lua.

However, I cannot seem to get all of the gpio pins to work. All other examples seem to work just fine but I can't for the life of me get an LED to blink besides on gpio2.

Does anyone know what I might be doing wrong?

Yes, I have tried the old firmware: ...12 and used both the new and old gpio pinouts.
I have also tried the new firmware: ...19 and used both the new and old gpio pinouts. It seems that gpio2 is the only one I can get to work on any of my modules (9 for old firmware or 4 for new firmware).

Is there something else I need to do when updating the firmware, besides simply flashing the nodemcu_512k_20141219.bin file and then rebooting?
