initiating the change or replacement of the one or more stack variables on the particular client node over the wireless medium.
8. The system of claim 7 , the operations further comprising:
responsive to a fourth input, selecting one of the client nodes from the plurality of client nodes in the network topology view;
responsive to a fifth input, sending a request to the selected client node for additional node information;
receiving the additional node information; and
presenting the additional node information on a display device.
9. The system of claim 7 , wherein the network topology view indicates routes and hops in the wireless sensor network.
10. The system of claim 7 , wherein the network topology view indicates timing and congestion in the wireless sensor network.
11. The system of claim 8 , wherein the additional node information includes event or state information of a stack in the selected client node.
12. The system of claim 8 , wherein sending the request to the selected client node for the additional node information and receiving the additional node information further comprises:
sending a memory read command to the selected client node with a memory address; and
receiving one or more values from the memory address; and
sending the one or more values to a hardware debugger or programmer coupled to a server device.
13. A non-transitory computer-readable storage medium having instructions stored thereon, which, when executed by one or more processors, causes the one or more processors to perform operations comprising:
initiating, by a server node over a wireless medium, a single debugging session with a plurality of client nodes of a wireless sensor network;
receiving, by the server node over the wireless medium, node information from the plurality of client nodes, wherein the node information includes, for each client node of the plurality of nodes, a first router address for the client node and a second router address for a parent node of the client node, a third router address for a next hop node for the client node and one or more variables used in a stack installed on the client node;
responsive to a first input, presenting, by a display device coupled to the server node, a network topology view constructed from the node information, the network topology view including a graphical representation of each client node of the plurality of client nodes in the topology;
responsive to a second input, presenting, by the display device, a variable watch window displaying one or more stack variables for a particular client node of the plurality of client nodes;
