Hi ,
What is the data receiving capacity of the S130 in observer role?

Hi,
This depends on your application. How often do you receive an advertising packet? Does the advertiser include a scan response? An advertising packet contains 28 bytes of usable data (31 with flags). A scan response contains 31 bytes of usable data. An advertiser can broadcast advertising packets 50 times a second. So in an ideal world where all packets make it to the observer we get a theoretical throughput of:
Without scan response:
50 packets/s * 28 bytes/packet * 8 bits/byte = 11.2 kbps.
With scan response on all packets:
50 packets/s * (28 + 31) bytes/packet * 8 bits/byte = 23.6 kbps.
(In a central mode the S130 supports one packet per connection event. In peripheral mode it is 2-3 packets per connection event)
