I need some programming help

  1. i would like to Know library associated with watchdog timer for nodemcu

  2. Currently my client code works on User defined wifi SSID and Password. If my product being used by others ,they will have different wifi network SSID & password. How can make universal wifi and password. where end user can connect to his own wifi network

  3. Assigning dynamic and static IP address in nodemcu unit

You cannot.

  1. Look at say Reverse engineering of the ESP8266 watchdog timer but state what you plan to do with it.
  2. The classic way of solving this problem is to force the ESP into AP mode and present the user with a web page to enter the local wlan credentials. See say GitHub - tzapu/WiFiManager: ESP8266 WiFi Connection manager with web captive portal
  3. See e.g. [SOLVED] Getting ESP8266-12E working as webserver with fixed IP not dynamic IP - Networking, Protocols, and Devices - Arduino Forum

I have got the code where i could able to interface

  1. Multiple SSID with single Nodemcu connected.SSID & pW is not secured
  2. User defined SSID & password preconfig
    3)SSID without password.

These 3 things can be easily achieved.

What about other things

Could you be more explicit about the issues which you still consider to be open ?
