Description
4.2.5 G2QRY: Single Gen2 Tag Query
G2QRY {Q} {sel} {session} {target} {M}
Perform a single tag query
NOTES:
1. The actual number of EPC words returned is defined in the Protocol Control word. The number of
words can be any value between 0 and 6. The shown configuration (number of words = 6) is typical.
Refer to the G2WRITEEPC command (section 4.4.3) for detail on the defined number of EPC data
words.
2. The PC and CRC words are delimited from the EPC identifier with underscore characters.
3. No response is returned if a tag query fails.
This mode performs a single tag query function on a single RF channel. When a tag is successfully
queried, the EPC identifier is displayed on the terminal and the buzzer will output a short high-
pitched chirp (if enabled).
The current RF channel is either the last retained RF channel from one of the three continuous query
modes or manually set through the RFCHAN command. The current RF channel may be read
through the following direct debug command:
The returned value will be a value between 1 (0x01) and 50 (0x32).
Regardless of the success of the command, the RF will remain enabled.
