CC2640 max scan duration

Hello, from the BLE V4.1 Core spec: "During scanning, the link layer listens on an advertising channel index for the duration of the scan window, scanWindow. The scan interval, scanInterval, is defined as the interval between the start of two consecutive scan windows. ..... The scanWindow and scanInterval Parameters shall be ess than or equal to 10.24s. The scanWindow shall be less than or equal to the scanInterval. If the scanWindow and scanInterval params are the same, the link layer should scan continuously."

If its like TIs other params, its in units of 1.25milliseconds and thus has a max of 8192.

Hi Ben,

As you figured out, the maximum duration is 65535 ms.

Hi Cetri,

After setting this parameter to 65535 I query it by reading it out of the stack:

uint16_t temp;

GAPCentralRole_GetParameter(GAPCENTRALROLE_MAX_SCAN_RES, &temp);

The value of temp is not 65535; it's 5000 which is the last value I had it set to.  Any thoughts?

Thanks,

Ben

Sorry, I posted the wrong line of code. This is what I am using to query the scan duration:
temp = GAP_GetParamValue(TGAP_GEN_DISC_SCAN);

Thanks for confirming!
