Android Question running the app with ROOT permission

[yaniv hanya]

i built an app the send commands to ModBus protocol. the people that built the slave (the device that get the commands), says that the app have to grant a "root" permission for sending the commands.
how do i give the app ROOT permission? can it be done via the app menifest?

This is probably where the root permission is required.
