    Your search engine didn't return the multiple results for this exact command for this exact product? Try another one then. – Sami Kuhmonen May 13 '17 at 05:20

what does the AT+CWDHCP? command return?

The (current) documentation

http://espressif.com/sites/default/files/documentation/4a-esp8266_at_instruction_set_en.pdf

states

4.2.14. AT+CWDHCP—Enables/Disables DHCP

[@deprecated] This command is deprecated.

Please use AT+CWDHCP_CUR or AT+CWDHCP_DEF instead.

You did not state which firmware version you are working with, so this may not be applicable. But the return value is described as 

Returns: DHCP disabled or enabled now? 
Parameters
* Bit0:
  - 0: Station DHCP is disabled.
  - 1: Station DHCP is enabled.
* Bit1:
  - 0: SoftAP DHCP is disabled.
  - 1: SoftAP DHCP is enabled

So, decoding those bits, the decimal return values should represent these states:

  • 0 "SoftAP DHCP is disabled" and "Station DHCP is disabled"
  • 1 "SoftAP DHCP is disabled" and "Station DHCP is enabled"
  • 2 "SoftAP DHCP is disabled" and "Station DHCP is disabled"
  • 3 "SoftAP DHCP is enabled" and "Station DHCP is enabled"
handle
  • 5,859
  • 3
  • 54
  • 82
