1.7 Security concept, Bluetooth operation
Sensor adjustment via Bluetooth is based on a multi-stage security
concept.
Authentication
When starting Bluetooth communication, an authentication is carried
outbetweensensorandadjustmentdevicebymeansofthesensor
PIN. The sensor PIN is part of the respective sensor and must be
enteredintheadjustmentdevice(smartphone/tablet).Toincrease
adjustment convenience, this PIN is stored in the adjustment device.
This process is secured via an algorithm acc. to standard SHA 256.
Protection against incorrect entries
In case of multiple incorrect PIN entries in the adjustment device,
further entries are possible only after a certain amount of time has
passed.
