Define a format for the package. This can also be done after initialization of the decoder class, for example if you wish to select for format based on UID, customerID or customerData
LPformat = loraPayLoad()
Define format items as , , <REPRESENTATION CHOOSE: INT, STRING or FLOAT>
LPformat.addItem('TEMP', 1, 'INT') # Add item TEMP that is represented in the first byte as an integer in the payload
LPformat.addItem('HUM', 1, 'INT') # Add item HUM that is represented in the second byte as an integer in the payload
Define a new loraPacketDecoder class
Lp = loraPacketDecoder(RAW_LORA_DATA, LPformat)
## Lp.setFormat(LPformat) # for setting the format after initialization
Print the received data using the format
for (key, value) in lpD.getPayloadItems().iteritems():
print key, value
