Using Arduino Programming Questions
1

Hello,

  1. When i call mesh.update(), i would like to know if the node is connected. I see the api,

isConnected exist; how can i use this function?

  1. what is the goal of sendSingle than use Task taskSendMessage( TASK_SECOND * 1 , TASK_FOREVER, &sendMessage ); ?

Thank you for your help.

I don't understand your second question. But, the documentation for isConnected() seems fairly self-explanatory:

Except for what looks like a typo. It should probably read:

Returns true if a given node is currently connected to the mesh.

What is it that you don't understand?
