CC2650 BLE Scan interval and duration

Syama Sasikumar

Hi,

I am using CC2650 as a BLE receiver. I am using the sample code simpleBLEObserver.c in ti ble stack as reference.The parameter DEFAULT_SCAN_DURATION is mentioned , but it seems there is no provision to configure the SCAN_INTERVAL (allowed value of scan interval in BLE is from 20 ms to 10.24 s). Could you please tell me whether there is any provision to configure both scan duration as well as interval.

Thanks in advance !!!

Hi,

Please take a look at our software developer's guide page 122.
ex:
TGAP_CONN_SCAN_INT
TGAP_CONN_SCAN_WIND
there are more configurable scan interval/window parameters, which can be easier set by using GAP_SetParamValue();

Hi,

these parameters can be set to n * 0.625 ms. Could you please explain the significance of the constant 'n'?

Could you please explain the difference between parameters TGAP_GEN_DISC_SCAN and TGAP_GEN_DISC_SCAN_WIND ?

One is scan interval(interval between each scan event) and the other one is scan window(time used in each scan(from starting point to the end.) )

TGAP_GEN_DISC_SCAN_INT parameter defines the scan interval right? and TGAP_GEN_DISC_SCAN_WIND defines the scan window....then what does TGAP_GEN_DISC_SCAN signify?

It's just the name for general discovery.
