?AP | The Tags actively transmit, and the Reader picks them up and stores them into | |
Auto Poll Time | an event cue. "Auto poll" tells the Reader how often to read the cue. | |
The | ||
| ||
| and disable the auto poll feature when Channel 139 is OFF. | |
| • Range = 50 to 6000 milliseconds (ms) | |
| • Default = 2000 ms | |
| Response: AP <MLSEC> | |
| Where: | |
| • MLSEC: mlsec in the polling interval (Range = 50 - 6000 ms). | |
| Examples: | |
| SEND_COMMAND '?AP | |
| Master requests current auto poll time interval. | |
| SEND_ COMMAND 'AP 5000 | |
| Master set, or | |
|
| |
?TG | The Tag Information (TG) command is sent by the Master to request the cur- | |
Tag Information | rent Tag status on the | |
Note: This command will only report status on Tags that pass through the | ||
| ||
| Reader Filters. | |
| The Tag message may contain information about more than one Tag bounded | |
| by the maximum length of an AXLink message (64 bytes). | |
| Response: TG [T<TID> R<RSSI> P<LIFE> A<AFLG> B<FUT> …] | |
| Where: | |
| • TID: The tag's unique Tag ID, an 8 character string formatted such that a | |
| tag's type can be identified by the first character. | |
| • RSSI: RSSI strength value of tag's transmission | |
| (Range = 0 - 255, where 0 = no signal, and 255 = max RSSI signal possible). | |
| • LIFE: The Percent of Battery Life left on the Tag (0 - 100%). | |
| • AFLG: Activity Flag, a single byte denoting if the tag has just crossed the | |
| Acquired Threshold and been acquired; just crossed the Lost Threshold and | |
| is lost, or the change in RSSI value since the last sent Tag RSSI value is | |
| greater than the Sensitivity range. Values are: | |
| 2 for acquired, | |
| 1 for RSSI value change, | |
| 0 for lost. | |
| • FUT: Future Flag, a single byte to be populated in the future to signal an alert | |
| when tags include tamper proof indicators or to signal a push and release | |
| event when tags are created with a button. In this release will be set to 0. | |
| Examples: | |
| SEND_COMMAND '?TG | |
| Master requests the current tag status on an | |

| SEND_ COMMAND 'TG T12345678 R45 P25 A2 B0 T87654321 R234 P80 A1 B0 | |

| • TagID:12345678 RSSI:45 battery:25% has just been acquired; | |
| • TagID:87654321 RSSI:234 battery:80% has changed RSSI value | |
