My Problem: I've got 802.15.4 Wireless network connected to a serial port (using a wrapper). I can send packages into the network and listen for incoming packages. As you can imagine this is highly asynchronous.
Here comes the task: I want to send commands to the network and wait for the response in one function call. For Example: I want to get the temperature from the Node with the network ID 1338.
double getTemperature(int id) throws Exception { .... }
Is there a better way of waiting for a response message other than doing all this "synchonized(object) wait(..) notify(..)" stuff?
Best regards, bigbohne
Maybe to add some spice:
This should all end in a webinterface where user can request these commands (either through ajax or directly). I've also thought of caching responce values in a database. But for some commands you MUSS have a direct answer of success/failure
