Installation

pip install redrcp

Usage

Connect to the reader

# Create driver
reader = RedRcp()

# Connect
reader.connect(connection_string='COM3')  # windows
#reader.connect(connection_string='/dev/ttyUSB0')  # linux
#reader.connect(connection_string='/dev/tty.usbserial-001')  # macos

... use the reader ...

# Disconnect reader
reader.disconnect()

Get basic information about the reader

manufacturer = reader.get_info_manufacturer()
fw_version = reader.get_info_fw_version()
model = reader.get_info_model()
details = reader.get_info_detail()

Sample response values:

manufacturer = 'PHYCHIPS'

fw_version = 'RED4S_v2.2.1_K'

model = 'R4S5U1DK-E'

details = ArgumentsReaderInformationDetail(region=<Region.Europe: 49>, channel=13, read_time=380, idle_time=100, cw_sense_time=5, lbt_rf_level=-74.0, current_tx_power=27.0, min_tx_power=13.0, max_tx_power=27.0, BLF=250, modulation=<ParamModulation.MILLER_4: 2>, DR=<ParamDR.DR_64_DIV_3: 1>)

Configure the reader

# Set TX power level
logging.info('Setting max TX power')
reader.set_tx_power(details.max_tx_power)
tx_power: float = reader.get_tx_power()

Perform continuous asynchronous inventory

# Define callback
def notification_callback(tag: NotificationTpeCuiii):
    logging.info(tag)


# Configure the callback
reader.set_notification_callback(notification_callback=notification_callback)


# Start inventory stream
reader.start()

# Do other stuff
time.sleep(.5)

# Stop inventory stream
reader.stop()

Sample report:

NotificationTpeCuiii(pc=bytearray(b'0\x00'), epc=bytearray(b'0\x083\xb2\xdd\xd9\x01@\x00\x00\x00\x00'))

Execute Read/Write operations

reader.write(epc='010203040506070809101112',  # or bytearray
             target_memory=ParamMemory.USER, 
             word_pointer=0, 
             data='1234')  # or bytearray

data: bytearray = reader.read(epc='010203040506070809101112', # or bytearray
                              target_memory=ParamMemory.USER, 
                              word_pointer=0, 
                              word_count=1)
