as you can see you need to flash LoBos AT firmware at 0x1000
from esp8266_at_lobo.

Could you please tell me where in the flash.sh script it is located? Thanks

This is the flash log. Is it ok that ESPTool says 0x00001000? Because the shell script reports 0x001000

Well it still the same after the first reboot. So I guess not :(

@loboris any hints?

Self compiled. I can upload my code no problem and it works. It is just strange that the AT did not work.

I don't quite understand what is the problem.
First, you flash the firmware using the flash.sh script:
boris@UbuntuMate:/home/LoBo2_Razno/MAIX/ESP8266_AT_LoBo/at_lobo$ ./flash.sh

After the flashing the ESP8266 will stay in the bootloader mode and has to be reset.
Start some terminal emulator, the included PyTerm.py works well (--reset option can be used to rested the board). After the ready, the board is ready to accept AT commands, type some.
boris@UbuntuMate:/home/LoBo2_Razno/MAIX/ESP8266_AT_LoBo/at_lobo$ ./PyTerm.py --reset
Namespace(baudrate=115200, device='/dev/ttyUSB0', reset=True)

@loboris maybe it could be nice to add info
like "ESP8266_AT_LoBo v1.2.4/selfcompiled" just before "ready" to have some info about version?
I'm sure more users will come with problems =)

Users usually have the ESP8266 board connected to some microcontroller and the early boot messages do not mean much.
For the version information you have the the AT command AT+GMR.

Well maybe there is a problem with PuTTy. I tried sending AT+GMR then pressed enter and nothing happened. So maybe the problem is on my side
