any way to take a photo from the linux command line via telnet ?

[netspoon]

Hi,

I see there is the option to send json to port 7878
eg: {"msg_id":257,"param":0,"token":0,"heartbeat":1}

And commands to put in an autoexec script
eg: t app key

Is there a command in Yi linux command line to do something similar, to be able to write scripts to run in the linux OS on Yi 4k ?

Thanks
