Compiler/CC2640R2F: What's timing for scanning window/interval while scan for 1M and Coded at the same time.

Hi All,

We use scanner for both 1M and Coded at the same time and find the throughput is bad.

        GapScan_setPhyParams(SCAN_PRIM_PHY_1M, SCAN_TYPE_ACTIVE,
                             DEFAULT_CONF_SCAN_INTERVAL,
                             DEFAULT_CONF_SCAN_INTERVAL);

        // Set Scan PHY parameters
        GapScan_setPhyParams(SCAN_PRIM_PHY_CODED, SCAN_TYPE_ACTIVE,
                             DEFAULT_CONF_SCAN_INTERVAL,
                             DEFAULT_CONF_SCAN_INTERVAL);

temp8 = SCAN_PRIM_PHY_1M | SCAN_PRIM_PHY_CODED;

GapScan_setParam(SCAN_PARAM_PRIM_PHYS, &temp8);

What's expected timing behavior while scanning 1M and CODED at the same time and what's possible cause of bad throughput.

Hi Sam,
What do you mean with bad throughput? Are you referring to scanning results?

Hi Lindh,

yes I meant poor through on scanning result.

I have several BLE4 and Coded Phy beacon around and if I scan legacy-only or Coded-Phy only the throughput of scanning result is ok.

However if I scan 1M and Coded Phy at the same time the throughput of scanning result is bad.

(Lots of Coded Phy ADV missed)

BR,

Sam

Hi Sam,

The module is not written to scan on both LE 1M PHY and LE Coded PHY simultaneously. Please set either LE 1M PHY or LE Coded PHY.
