A code snippet showing when and how to trap unexpected disconnection events.

disconnectTrap.device.nut

// EARLY CALL CODE
server.setsendtimeoutpolicy(RETURN_ON_ERROR, WAIT_TIL_SENT, 30.0);

// GLOBALS
local disconnectedFlag = false;
local disconnectedCount = 0;

// FUNCTIONS
function mainProgramLoop() {
    // We'll fill this in below
}

function disconnectionHandler(reason) {
    // Function called automatically if the agent link is lost
    if (reason != SERVER_CONNECTED) disconnectedFlag = true;
}

// START OF RUNTIME
server.onunexpecteddisconnect(disconnectionHandler);
