Point to point communication with low-power device

A node of a networked system, comprising:

• a processor configured to execute non-transitory computer-readable instructions;
• a memory configured to store the computer-readable instructions that, when executed by the processor, cause the processor to perform operations comprising:
• entering a sleep mode;
• entering a wake mode to listen for a wake signal from a diagnostic tool;
• while in the wake mode, receiving the wake signal from the diagnostic tool on a wake wireless channel, wherein the wake wireless channel is selected using a unique identifier of the node;
• establishing a communication link with the diagnostic tool on a communication channel different from the wake wireless channel;
• and performing a diagnostic operation with the diagnostic tool over the communication channel.

A non-transitory computer-readable medium having instructions stored thereon, the instructions executable by a processing device to perform operations comprising:

• controlling a low-power endpoint to enter a sleep mode;
• controlling the low-power endpoint to enter a wake mode to listen for a wake signal from a diagnostic tool;
• receiving the wake signal at the low-power endpoint from the diagnostic tool on a wake wireless channel, wherein the wake wireless channel is determined from a unique identifier of the low-power endpoint;
• controlling the low-power endpoint to establish a communication link between the low-power endpoint and the diagnostic tool on a communication channel different from the wake wireless channel;
• and
• controlling the low-power endpoint to perform a diagnostic operation with the diagnostic tool over the communication channel.
