1. A method comprising:
initiating, by a computing system, a wireless roam for a sensor from a source AP to a target AP by:
triggering the sensor to lower its transmit power below a threshold; and
in response to the sensor receiving a Basic Service Set (BSS) transition management (BTM) request from the source AP, wherein the BTM request comprises a list of BSS transition candidates including the target AP, causing the sensor to send a BTM response to the source AP accepting a transition to the target AP;
monitoring, by the computing system, management traffic between the sensor and one of the source AP or the target AP during the wireless roam;
in response to detecting an anomaly in the management traffic, reinitiating, by the computing system, the wireless roam for the sensor from the source AP to the target AP;
initiating, by the computing system, management traffic capture on the sensor during the reinitiated wireless roam; and
identifying, by the computing system, a roaming issue for the sensor based on analysis of the captured management traffic; and
reporting, by the computing system, the roaming issue.
