Connecting NodeMCU 1.0 Gateway to WiFi

Re: 💬 Building a WiFi Gateway using ESP8266
I have been able to use the example ESP8266Gateway sketch in Windows version of Arduino IDE to compile the sketch to my NodeMCU. This was possible by downgrading my board library to an earlier version as has been suggested. Now I am getting the following error in serial monitor after entering my SSID and pwrd:

421801 TSM:FAIL:RE-INIT
421826 TSM:INIT
421853 !TSM:INIT:TSP FAIL
421880 TSM:FAIL:CNT=7
421903 TSM:FAIL:DIS
421924 TSF:TDI:TSL

I am trying to connect this gateway to MyController Server on the same Wifi network before adding sensors on other nodes. Ultimately, this will be a multi-node weather station that can report various conditions from nodes placed across a 300+ acre plot of land. I am relatively new to all of this, including arduino and need some help. Thanks in advance.
