thanks for reply.
Similar situation here. I have not the time to go in deep with this modules,
just doing an independent communiction between several of it.
On the other hand, i had much fun with the ESP so far and get more curious
on details yet. It's not a realy urgent problem, so drop a message when you
have time .... and something interesting to say

cheers wally

not sure what "nodemcu" is but assume an alternative to the AT-firmware.
If so, may you be so kind and post a link to a ready firmware.bin ( please no SDK)
and some example commands or a link to those.

thank you wally

found this in german language, but clear and simple as for the firmaware request:

as for examples:

btw.: it works ! pretty much interesting hint, thanx to Vitoa

- Tue Mar 03, 2015 11:13 pm #11233 Well I managed to stuff two ESP-05's (0018000902-AI03) today so I won't be adding any useful info here for a day or two.
The first started outputting garbage and I hadn't changed any settings.
The second I played with the change baud rate setting AT+CIOBAUD=115200 and it put out garbage as well. Have played around with various baud rates on the terminal but to no avail.
The ESP-05 doesn't make it easy to update as the only pins readily available are the tx,rx,rst and supply pins.

https://github.com/nodemcu/nodemcu-flasher

And open this firmware file
https://github.com/nodemcu/nodemcu-firm ... 150212.bin

Select correct COM port, and dont forget to connect GPIO0 to ground to set flash mode.
Need also to connect other pin to vcc or ground.
For my modules (with metal shield) GPIO15 connect to ground, CH_PD connect top VCC, GPIO0 to ground and press flash. ESP-05 does not have GPIO's free u shoud buy ESP-07 is a really low cost with lots of IO's
U can see log tab to see if everything goes fine.
After flashing leave GPIO0 floating not connected, this puts module into normal mode.
Now u have a really powerfull unit
