- Sat Jan 09, 2016 2:12 pm #38326 AT+GMR gives the version.
(why do I bother typing?)

Does

Code: Select allAT+CIOBAUD?

work at all?

If not, that firmware probably doesn't support that command.
Poking around on the Internet, I found this:
Change the baud rate to 19200 with

Code: Select allAT+UART_DEF=19200,8,1,0,0

Found here: viewtopic.php?f=13&t=718

Also some notes here: http://michaelthessel.com/
In particular, this link might point to the most current version of the AT command set:

HI again..
i do not know what i have done,,but i think i may have done something right now...
i get this info now....which it never did before... so i think i may be on the right track now..

AT+RST


OK

ets Jan 8 2013,rst cause:4, boot mode:(3,6)

wdt reset
load 0x40100000, len 212, room 16
tail 4
chksum 0x5e
load 0x3ffe8000, len 788, room 4
tail 0
chksum 0x1c
load 0x3ffe8314, len 72, room 8
tail 0
chksum 0x55
csum 0x55
jump to user1
ready

Ok so now i try to follow the rest of the instructions on the
http://timewitharduino.blogspot.ca/2015/03/wifichron-with-software-support-for.html
at step 4 it says to change the baud rate.... this i do not know how to do.. i tried to do ( AT+CIOBAUD=38400 ) i get ERROR.
also i am not sure how to check what version i have.
but i think i am making some progress...

- Sat Jan 09, 2016 2:55 pm #38329 when i type in.. AT+CIOBAUD? i just get "ERROR"

and if i try to type in ... AT+UART_DEF=19200,8,1,0,0 i get the same ERROR reply..

perhaps i do not have the correct firmware ?
the firmware i put in was a BIN file ( ESP_8266_BIN0.92.bin ) perhaps a old update ?
The terminal does accept commands, but does not like them hence the ERRORS.
so for now i'll try to find a newer version..i read that different versions respond to different AT commands.
right now only basic commands work... AT AT+RST AT+GMR etc...
have faith in me. i am learning..
thanks for your help so far..

It would really be nice if you would type AT+GMR and send the output. (4)

That bin file does not match the one that is in the March 13th blog entry that you said you were working from nor the one I found and tested (which I believe to be one and the same).
I recommend that you

• go back to my reply here: viewtopic.php?p=38224#p38224
• and duplicate my results.
• Flash that exact firmware and get that exact version when you run AT+GMR.
• Until you do, all my help will be of no value.
• Once you do, then you'll be on a path consistent with Florin and you will be much more likely to have success.

- Sat Jan 09, 2016 3:33 pm #38334 ok, i think i am missing something here... do i need to be using a certain program to make the updates?
because when i poke around in the folder most items open in a COMMAND window and i have no idea what i am doing in there.. so i think that's where i am always getting lost... because i found the folder "v0.9.6_b1_15_02_15.zip. "
but have not been able to really use it..
