ESP WIFI visible but no com responce
Posted: Mon Nov 17, 2014 2:16 am
Hi my 3 modules of ESP8266 have arrived and i connected module to pc via FT232RL (fake one after unbricking) set to 3,3v
I've attached ch_pd to 3,3v tx to rx, rx to tx and gnd and 3,3. Ive tried baud rate 9600, 57600 and 115200.
The transmission led's blink on both esp and ft232(but only one per device) when i type in putty or press send on other terminal apps (even tried from android phoine).
I can see wifi network and can connect to it and get connection refused when connecting wia http to it's ip address.
But there is no responce on com port (cr lf line endings selected) no responce for AT , AT+RST , AT+CWLAP . there is also no garbage initially when open ing port etc. i've placed 1F capacitor just to be sure it's not sudden power drop issue (and wifi works for abaout a minute after disconnecting from pc).
Ive tried reversing tx rx but it didnt help.
Does anyone have any clue what can be the issue here
ps in firmware upload mode (gpio0 pulled down) updating app cant find device.
