Radio channel parameters
EMDCB transmits Bluetooth Low Energy (BLE) advertising telegrams within the 2.4 GHz
radio frequency band (2402MHz … 2480MHz).
By default, EMDCB will use the three BLE advertising channels (BLE Channel 37, 38 and 39)
defined for transmission. The transmission of a radio telegram on these three advertising
channels is called an Advertising Event.
Use of different radio channels within the frequency band from 2402 MHz to 2480 MHz is
possible using the NFC configuration interface, see chapter 7.
The initialization value for data whitening is set as follows:
◼
For BLE channels is set according to specification (value = radio channel)
◼
For the custom radio channels the initialization value is equal to the offset from
2400 MHz (e.g. value = 3 for 2403 MHz)
Table 2 below summarizes radio channels supported by EMDCB.
