Configure the NodeMCU

Download putty

https://www.putty.org/

Choose the version that is compatible with your laptop or pc.

Set-up putty.

Type help to access all commands and press CTRL + J to enter.

Type ipconfig to check on what SSID(name of wifi router or accespoint) the NodeMCU is currently connected.

type SSID= the SSID of the router or accesspoint you want it to connect to and then press

CTRL + J again

tip: Type fast, otherwise the command will not not be executed.

type ipconfig again and press CTRL + J to check if the SSID was updated.

Type AUTO_SCAN=2 to lock the connection between the NodeMCU and your SSID to prevent it from connecting to any other SSID when it restarts or when a stronger signal coverage is present.

Type env to see the updated status.

Payment Portal Settings

Open (auto-accept connections)

By default, your NodeCMU is set to auto scan. It means it will automatically scan wifi ssids and attempt to connect. If this setting is turned ON, your main vendo will automatically accept the connection request from sub-vendo. You will only turn this ON for setup purposes. After the sub-vendo has connected to your main vendo, fill the Token field and check/tick Automatically apply changes to connected devices and hit Save Changes

Security Token

Security token is the pre-shared token by your main vendo and your sub-vendo/s. Main vendo will only accept connection request from sub-vendos if they have matching security token, unless (auto-accept connection) is enabled.
