Wireless Device Pairing Recovery

A wireless sensor for incorporation as a wireless sensor node into a wireless personal area network (WPAN) via a pairing operation with a coordinator node, the wireless sensor including:

• a switch facilitating generating a sensor status signal;
• a processor;
• and
• a non-transitory computer readable medium including computer-executable instructions, executable by the processor, for facilitating actively purging, without operator intervention, coordinator entries from a pairing table for a wireless sensor node incorporated into a wireless personal area network by performing the steps of:
• registering a failure by the wireless sensor to connect to a first coordinator identified by a first coordinator entry in the pairing table;
• identifying at least a second coordinator entry in the pairing table corresponding to a second coordinator;
• determining that the wireless sensor has repeatedly failed to connect to the first coordinator a specified number of times over a time period;
• and
• purging the first coordinator from the pairing table in response to the identifying and determining steps.

A transportable refrigerated container system including:

• a refrigeration system including a controller;
• a wireless communication system configured as a wireless personal area network (WPAN), the WPAN comprising:
• a coordinator node;
• and
• a wireless sensor node, configured to sense a status of a control point in the refrigeration system and communicate the status to the coordinator node only after a pairing operation with the coordinator node, the wireless sensor node comprising:
• a switch facilitating generating a sensor status signal;
• a processor;
• and
• a non-transitory computer readable medium including computer-executable instructions, executable by the processor, for facilitating actively purging, without operator intervention, coordinator entries from a pairing table for a wireless sensor node incorporated into a wireless personal area network by performing the steps of:
• registering a failure by the wireless sensor to connect to a first coordinator identified by a first coordinator entry in the pairing table;
• identifying at least a second coordinator entry in the pairing table corresponding to a second coordinator;
• determining that the wireless sensor has repeatedly failed to connect to the first coordinator a specified number of times over a time period;
• and
• purging the first coordinator from the pairing table in response to the identifying and determining steps.
