I've used at firmware from sdk .0.9.1 and it works.

I've decided to upload the new at firmware from 0.9.5. But after boot I can't get any response from the module.

I'm compiling the AT example without OTA so I'm getting this message at the end:

Code: Select all!!!
No boot needed.
Generate eagle.flash.bin and eagle.irom0text.bin successully in folder bin.
eagle.flash.bin-------->0x00000
eagle.irom0text.bin---->0x40000
!!!


After boot this is what I'm getting:

at 74880bps:

Code: Select all ets Jan  8 2013,rst cause:1, boot mode:(3,4)

load 0x40100000, len 26540, room 16

Code: Select allБ▄▓`rlNЪ
ready



But after that no matter what I'm typing there is no response! I have echo but that's all!

Can someone help?
