Handling product identities
To secure that the FP and sensors do not make cross-
communications a unique ID is entered into the System
NVS data space of an FP or sensor. In DECT the ID for
the FP is named RFPI and for the Sensor the ID is
named IPEI. These numbers are factory settings and
are pre programmed in the One Time Programmable
(OTP) section of the NVS.
After a successful registration, the IPEI is stored in the
FP and the RFPI is stored in the sensor. In this way the
two parts are known to each other and are allowed to
make connections. The registration data are
automatically stored in NVS data space of the FP and
sensor while making the registration.
A sensor can only be used on one FP at the same
time, in order to communicate with a different FP a
registration cycle with that FP must first take place.
