modem.protocol.isoc.recomm<br />

This function recommissions an ISO-C tag in the field. The parameters<br />

supported by this function are:<br />

tag_id (optional) – Indicates the ID of the tag to recommission. If the<br />

tag_id is not supplied, the first tag found is operated on. The tag is first<br />

singulated and put in a state for the recommission operation.<br />

kill_pwd – Indicates the kill password required to perform the operation.<br />

recomm – Integer that indicates recommission operation to perform.<br />

You should have a thorough understanding of the ISO-C specification<br />

(Gen2 spec v1.2) in regards to tag recommissioning. The recomm<br />

parameter will become the 3 bit recommission operation sent to the<br />

tag. valid values are: 1, 2, 3, 4, 5, 6, 7.<br />

antenna (optional) – Indicates antenna on which to execute the<br />

function. If an antenna is not specified, all antennas will be tried until<br />

the function succeeds or no more antennas are available.<br />

The response to this function is a response name. The following example<br />

recommissions a tag with ID = 0x30112233445566778899aabb and<br />

kill_pwd=12345678. The recomm value of 2 causes User memory to<br />

become unusable:<br />
