ESP-01 Bootup and AT Command

[eso]

Hi,
I just started to play with 5 new ESP-01 and tried to connect them via terminal.
What I got under coolterm is this:

*EMRDY: 1

*EMRDY: 1
atOK
at+gmrR2A07(R2A07)

OK
at+rstERROR
at+gslpERROR
ateOK
at+cwmode=?ERROR
at+cipstart=?ERROR
at+cmd?ERROR
ateOK
ate1OK
at+rstERROR

So ... every AT command returns an error (except at, ate and at+gmr)
And the answer from gmr is quite strange, I didn't find any hint on the net.

Can you give me some hints? I don't believe all 5 chips are broken, they all behave the same way, so the mistake must be on my side.

Kind regards from Germany
Eric

Hi,

It should be "AT+GMR" "AT+RST", not "at+gmr" "at+rst".

There are documentations about AT commands: http://bbs.espressif.com/viewtopic.php?f=51&t=1022

Thanks for your interest in ESP8266 !

Thank you for your reply!
I've tried this before but here are the responses from today:

AT+RSTERROR

AT+GMRR2A07(R2A07)

OK
ATOK
ATEOK
ATE1OK
ATEOK
AT+CWMODE=?ERROR
AT+RESTOREERROR
AT+UART_CURERROR
AT+RFVDDERROR

It's just the same. I don't think it's that simple.
I obviously got a connection, but no basic AT command seems to work.
Flashing with an other FW doesn't work either.

Kind regards
Eric

Hi,

It seems that you are not using the AT commands provided by our company, Espressif Systems.

Would you like to have a try with our AT firmware ? You can download it from http://bbs.espressif.com/viewtopic.php?f=46&t=1123.

Thanks for your interest in ESP8266 !
