KW41Z BLE Scan

Question asked by sensenthuran on Oct 4, 2019

Hi,

 

All the iBeacon sources are close the the KW41Z (ble_fsci_black_box received  rssi ~65dBm) and all the sources  transmit iBeacons at 100ms transmit interval.

 

When we have  more than 3 iBeacons sources are active, then KW41Z with ble_fsci_black_box binary get all the scan results as expected. 

 

If we enable only one iBeacon source, kw41z returns only one scan result when we enable the ble scan. Then it does not give any scan results for several minutes (1-15 mins). 

If we have many beacon sources, then we do see all the scan results as expected.

 

Is there any filtering mechanism inside the  ble_fsci_black_box firmware?

 

Thanks

Sen
