EMDCB supports the following user-defined sequences:
◼
Three channel sequence
This sequence is similar to the default Advertising Event with the difference that the
user can select the radio channels to be used. The three channel sequence is de-
scribed in chapter 3.3.1 below.
◼
Two channel sequence
In this sequence the radio telegram is transmitted using six transmissions on two
radio channels. It is described in chapter 3.3.2 below.
◼
One channel sequence
In this sequence the radio telegram is transmitted using nine transmissions on one
radio channel. It is described in chapter 3.3.3 below.
3.3.1
Three channel sequence
The three channel radio transmission sequence is similar to the default transmission se-
quence with the difference that the radio channels (BLE Channel 37, 38 and 39 in the de-
fault transmission sequence) can be selected using the registers
TX_CHANNEL1
,
TX_CHANNEL2
and
TX_CHANNEL3
.
In this mode, the telegram will be transmitted on the radio channel selected by
TX_CHANNEL1
first, immediately followed by a transmission on the radio channel selected by
TX_CHANNEL2
and a transmission on the radio channel selected by
TX_CHANNEL3
.
The telegram will be transmitted using this sequence three times in total as shown in Figure
8 below.
This transmission uses a default
INTERVAL
setting of 20 ms; an alternative setting of 10 ms
can be configured via NFC.
