sint8 tstrM2MScanOption::s8RssiThresh

The Received Signal Strength Indicator threshold required for (fast) reconnection to an AP without scanning all channels first. Refers to active scan as part of reconnection to a previously connected AP. The device connects to the target AP immediately if it receives a sufficiently strong probe response on the expected channel. Low thresholds facilitate fast reconnection. High thresholds facilitate connection to the strongest signal. Valid settings are in the range -128<=Thresh<0. Default setting is M2M_FASTCONNECT_DEFAULT_RSSI_THRESH.

uint16 tstrM2MScanOption::u16PassiveScanTime

The length of each scan slot in milliseconds. Refers to passive scan only. The device listens for beacons during this time. Valid settings are in the range 10<=PassiveScanTime<=1200. Default setting is M2M_SCAN_DEFAULT_PASSIVE_SLOT_TIME.

uint8 tstrM2MScanOption::u8NumOfSlot

The number of scan slots per channel. Refers to both active and passive scan. Valid settings are in the range 0<Slots<=255. Default setting is M2M_SCAN_DEFAULT_NUM_SLOTS.

uint8 tstrM2MScanOption::u8ProbesPerSlot

Number of probe requests to be sent for each scan slot (when not specifying network to scan). Number of probe requests to be sent for each ssid to scan in each scan slot (when specifying network to scan). Refers to active scan only. Valid settings are in the range 0<Probes<=2. Default setting is M2M_SCAN_DEFAULT_NUM_PROBE.

uint8 tstrM2MScanOption::u8SlotTime

The length of each scan slot in milliseconds. Refers to active scan only. The device listens for probe responses and beacons during this time. Valid settings are in the range 10<=SlotTime<=250. Default setting is M2M_SCAN_DEFAULT_SLOT_TIME.
