B.
Receiver configuration for BLE
PTM 535BZ transmits sensor information as a set of advertising events either on the BLE
advertising channels or on user-defined radio channels as described in
Chapter 3.2
To maximize the likelihood of reception of these telegrams, it is necessary that the receiver
is either permanently in receive mode on one of the radio channels used by PTM 535BZ or
–
if this is not possible
–
periodically in receive mode for a sufficiently long duration.
B.1
Scanning parameters
Three key timing parameters have to be considered when configuring a receiver (scanner)
for periodical reception of advertising events sent by a transmitter (advertiser). These three
parameters are:
◼
Advertising interval
Time between two advertising events sent by the transmitter
◼
Scan interval
Time between the start of two consecutive scanning cycles of the receiver
◼
Scan window
Duration for which the receiver will scan within each scanning cycle
below illustrates these three parameters.
