3 ini: roam_data_rssi_threshold_triggers roam_data_rssi_threshold rx_data_inactivity_time If there's rx activity during latest rx_data_inactivity_time and avg of data_rssi is better than roam_data_rssi_threshold, then suppress roaming triggered by roam_data_rssi_threshold_triggers: low RSSI or bg scan.
