Wow, that's new - I didn't know there was a 1.3 version!

Did you run the 'version checker'? http://www.espruino.com/ESP8266

I'd be interested to know what it reports (since it also checks baud rate). It might be that the new firmware uses a different baud rate and that's your problem?

Thanks @gordon,

I ended up using AT version 0.50 and it seems to working OK.

Thanks

Thanks for letting me know! Perhaps version 1.3 was doing something strange

seems like latest esp-01 no longer comes with AT 0.25 / 0.50.

If any stuck then please use the attached firmware and re-flash your esp-01.

use the following commands

Change the port if you have different. Oh, also it is for 1MB flash.

esptool.py -p /dev/tty.SLAB_USBtoUART -b 115200 write_flash 0x00000 eagle.flash.bin 0x10000 eagle.irom0text.bin 0x7E000 blank.bin 0xFE000 blank.bin 0xFC000 esp_init_data_default.bin

Thanks! Is that the 0.50 firmware? I'll stick it on the main Espruino site.

It'd be interesting to see why the new firmware doesn't work though - it could just be a different baud rate I guess.

Hi @gordon, I have re-uploaded the attachment from espressif website. This is the one I tested and worked.

I don't think it is the baud rate, I did a few debugging, it seems like it is problem detecting the "ready"

Hope it helps.
