Re: 2 new importants requirements in AT firmware

Dear Sir,

The current SDK supports hardware flow control by default. Please make a try.

Only MTCK(GPIO13) can be reused as UART0 CTS and MTDO(GPIO15) can be reused as UART0 RTS. CTS/RTS can not be swapped to GPIO0/GPIO2.

Please be noted.

Thanks.

Re: 32Khz crystal

Dear Sir,

In our Chinese version of ESP8266 datasheet, we have already removed this part, because we do not support this now.

We will update the English Version of ESP8266 datasheet ASAP.

So sorry for our mistakes that make you confused.

Re: IO voltage pins

Hi,

Digital and IO Power Supply(Pin 11, Pin 17): 1.8V ~ 3.3V

Analog and PA Power Supply(Pin 1, Pin 3, Pin 4, Pin 29, Pin 30):3.0V ~ 3.6V.

Voltage of 2 AA batteries is ok.

How can you obtain master_device_key.bin?

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...

Re: IO voltage pins

Dear Sir, Thank you for your questions. Both two VDDPST are digital and IO power supply and the source is the same.The reason for using two VDDPST is to prevent the possible insufficient power supply current. The recommended voltage of VDDPST is 3.3V. Any more questions, please feel free to contact ...
