Harmonize RFID checksum in transmission and comparison

There was the problem, that some already existing RFID tags are not working anymore. The reason is that the new LoRa boxes transmitting two bytes less than the old ones. For example:

  • 30007B7D0036 in database
  • 30007B7D00 from new box

We assume that the old boxes transmitted the checksum too, while the new lora boxes not. The CRC-8 checksum of 30007B7D00 is 36, which fits.

We have to

  • Define if the database should the checksum or not
  • Harmonize the behavior of the system
