OTA service uses firmware version to decide whether to start update or not. we need to set below GET route at server (e.g. server.com)
GET route format as ==> http://server.com/ota

In parameters, device will provide the mac address and the current firmware version. Based on this inputs from the device server should provide the response of latest version available on server in below json format.
{ "latest": 2020053012 }by default update start only if device current firmware version is older than received firmware version from server.
when device start the update process after knowing its current firmware version is older it looks for the downloadable binary file from the same server in format given below
server address / bin / device mac address / latest firmware version .bin file
e.g. http://server.com/bin/xx:xx:xx:xx:xx:xx/2019041101.bin
