I can talk to it and all works ok so far. However, I'd like to update the firmware as the one that is installed does not have the features decribed in the AT description.
Here is what I do:
AT+RESTORE
.....
invalid
AT+CWMODE_DEF=3
OK
AT+CWDHCP_DEF=1,1
OK
AT+CWJAP_DEF= [ssid], [pwd]
WIFI CONNECTED
WIFI GOT IP
OK
AT+GMR
AT version:0.40.0.0(Aug 8 2015 14:45:58)
SDK version:1.3.0
Ai-Thinker Technology Co.,Ltd.
Build:1.3.0.2 Sep 11 2015 11:48:04
OK
AT+CIUPDATE
+CIPUPDATE:1
+CIPUPDATE:2
+CIPUPDATE:3
+CIPUPDATE:4
ERROR
Any idea what is wrong?
Thanks for any hint.
PS. The update with esptool.py failed as well, after booting with GPIO0 pulled down I cannot connect to the device, the pytton tool says
Connecting...
A fatal error occurred: Failed to connect to ESP8266
