SDK 0.9.5 + new AT 0.21 doesn't work???

[rgregor]

Hello,
I have downloaded SDK 0.9.5. I am able to compile it and everything is fine. However, I wanted to check the new AT commands 0.21. So based on the SDK, I went to esp_iot_sdk_v0.9.5\bin\at\ directory and did exactly, what is in the readme:

boot_v1.2.bin 0x00000
user1.512.new.bin 0x01000
blank.bin 0x3e000 & 0x7e000

But after that, when I start the module, I don't have anything going out even any answer to AT. Only when power on, I have this:

Œlìb|Ž‚ì’r’blbŒònnžlnnœâìbpìŽlrlrl‚rò’nàbânbp

What I am doing wrong. Should I also load the user2.512.new.bin ? At which address?

After loading of the old AT firmware, everything is fine and working, so there is no issue with the connection, hw or something like that.

Hello, I see. Ok, thanks a lot for the quick reply. It is working now. The problem probably was, that I was using that simple flasher tool and I updated in the order boot, user1, blank, blank. Seems this doesn't work. But with that esp flasher tool it is now working...

Thx!
