I have a design working with standard ESP8285 with 8Mbits flash. I bought the new ESP8285H16 on Mouser last week for a new batch of the same design. I've downloaded last "Download tool" and "AT firmware" but couldn't get it to work.
I've attached a picture with the programming tool's configuration and result.
I've added a terminal window on the bottom left, this is what I receive after a reset.
Seems pretty good BUT the module doesn't respond to AT commands (I change for 115200bps of course). It doesn't start the Wifi AP like on previous version.
Could you please help me understand where is the issue ?
I assume it has something to do with addresses.

AT version:18.104.22.168(May 11 2016 18:09:56)
compile time:May 20 2016 15:08:19
I want to be able to use the AT+CIPSNTPTIME functions, but it appears my version doesn't have it...
The OTA update doesn't appear to be an option either, I send "AT+CIUPDATE" and the response is "ERROR"
I am definitely connected to the internet in station mode via my home access port as I can ping outside addresses with the AT+PING command.
I can't seem to update the firmware either. It appears that I have wired GPIO0 correctly, as when I hold it to ground during a reset then I can't talk to it in AT mode, so I presume it is in flash mode.
But whatever I try I get this error response from the firmware updater:
CONNECT BAUD: 115200

Can anyone tell me what I'm doing wrong???
Maybe try to download it with the latest tool? https://www.espressif.com/sites/default ... v3.6.8.zip
