- Sat Apr 30, 2016 10:25 am #46552 hi there..im new here and tryin to get my esp01 runnin..apologies if it is been answered before..i did search the forum and still cant get it to work.
my problem is as soon as i get the ready message on serial monitor, esp disconnects with a message "wifi disconnect", it starts again, ready and disconnects again.. i also cannot send any commands to esp thing because of it disconnecting i guess.
im using arduino uno to connect and an external power supply with lf33cv to regulate power..i just checked the voltage on the circuit and it is 3.18 volts(is it the problem?)
gpio2 is pulled high (with/without a resistor or floating, without ne difference)
vcc is connected to external power 3.3v
ch_pd is connected to vcc with a 0.5k resistor
rx, tx are connected to arduino uno without the atmega chip
reset is pulled high with a 0.5k resistor and a push button
gpio0 is pulled high with a resistor and a push button(floating or pulled high without resistor makes no diff)
ground of arduino, external psu and esp is connected

if it is of ne help, while it is disconnected i still see the aithinker in my available wireless network list

If you use the AT+CWJAP command, the AP and the address are saved. So, seeing Wifi Disconnect is normal especially when you do AT+RST.

Anyway, RST is not connected, GPIO0 is not connected, GPIO2 is not connected. CH_PD is connected to VCC.

RST is not connected, GPIO0 is not connected, GPIO2 is not connected.

Those 3 pins should also been pulled-up to VCC...

- Mon May 02, 2016 8:51 pm #46737 Is there official documentation about this?

Tutorials on I have seen on internet do not have those pins connected.
