Launches a separate thread for each of them, so they are done in parallel, then waits for them all to complete. This doesn't change how the Snap! scheduler works; the threads are not truly asynchronous. And there is no increase in speed. Rather, the point of this block is to allow starting synchronized but independent scripts.

pt:a localização actual do dispositivo Connect to a broker The options are not required but can be filled if needed 1. username (some brokers need this) 2. password (some brokers need this) 3. keepalive (default time is 60 seconds but some brokers need a shorter time) 4. connection callback (ringed set of scripts to be run when connection is made or remade) Note: The connection callback doesn''t have to be the 4th option - it just has to be the last (or only) option. ADVANCED: The brokers offered in the menu are accessed using default ports and basepaths (if needed). If accessing other brokers, the complete urls should be formed like this: siteURL:port/basepath e.g mqtt.eclipseprojects.io:443/mqtt It is possible to have more than one connection to the same broker, for instance, using two different user/pass accounts simultaneously. To do this, add a connection id at the end of the broker: e.g mqtt.eclipseprojects.io:443/mqtt|1
