Hi @roop
We use Network Manager in resinOS2.x to manage the devices connections. Network Manager supports both creating access points and automatically bridging the connection between multiple interfaces.
Just drop the below example configuration into a file inside the /boot/system-connections directory on the SD card and name it resin-hotspot, next use the Network Manager DBUS API to enable the connection called resin-hotspot.
You will then be able to connect to the hotspot using resin-hotspot as both the SSID and password.
As a bonus this hotspot method automatically bridges the connection!
