How can you obtain master_device_key.bin?

[Espressif_Kelly]

Hi everyone,

If you want to use our server to realize internet control, you may need to download master device key.bin(0x3e000) into the external flash of ESP8266.

Master device key.bin, the only value that can identify the device,can be generated by yourself in our iot.espressif.cn website.

You can refer to "3-CLD-Espressif Cloud Introduction_v3.pptx" that we have released to you for details.

Thanks.

Hi Kelly
this was a very important point - thank you for the "puplic" info.
some people do not know how this key is handle and - why this key is need ..
so now some people know why this key is need and that the key is a important doing in "Cloud".
and if key is wrong, that not possible to do things at the Cloud.
best wishes
