modem.protocol.isoc.conf_test
Generate the appropriate ISO-C conformance test commands. Can also be
used to send specific bit stream of data. The parameters supported by this
function are:
command (optional) - The Gen2 conformance command sequence.
data (optional) - The data bits to be sent using ISOC transmission.
num_bits (optional) - The number of bits from the parameter to be sent.
>>> modem.protocol.isoc.conf_test(command=QUERY)
The following command sends bits 101010100b using the ISOC protocol.
>>> modem.protocol.isoc.conf_test(data=0xaa55,
num_bits=9)

modem.protocol.isoc.read
This function reads specified data from an ISO-C tag in the field. The
parameters supported by this function are:
tag_id (optional) – Indicates the ID of the tag to read. If the tag_id is not
supplied, the first tag found is read. The tag is first singulated and put in
a state for a read operation.
pwd (optional) – Password used to read locked portions of a tag.
mem_bank – Specifies which tag memory bank is to read
(0 = Reserved, 1 = EPC, 2 = TID, 3 = User memory).
word_ptr – Specifies the starting word (16 bit) address in the memory
bank for the read.
word_count – Specifies the number of 16-bit words to read. If the
word_count = 0 the entire memory bank is read.
antenna (optional) – Indicates antenna on which to execute the
function. If an antenna is not specified, all antennas will be tried until
the function succeeds or no more antennas are available.
The following example reads four words at offset 2 from the user memory
section of a tag with ID = 0x30112233445566778899aabb:
