HI everyone
from past few weeks I am using 8266 -12 with breakout board from ExploreEmbedded, I did not have any problem. But today I bought 8266 12E from ebay without breakout board.
To Flash the nodemcu I connected
vcc --> 3.3v
ch_pd -- > 3.3v
tx -- >rx
rx --> tx
gpio2 --> 3.3v
gnd --> gnd
gpio15 --> gnd
gpio0 --> gnd
with this I was able to flash nodemcu.
the problem started with esplorer and arduino ide
i removed gpio0 from gnd and rebooted . it cant detect firmware in esplorer also i cant send any files or commands to chip.
I tried various circuit configurations like removed gpio2 and gpio15 connextions made them float,...connected gpio0 to high but nothing working..if i make gpio2 float , garbage is displayed when i connect reset to gnd..
please help me out in this
Thank You
