about BLE_GAP_PHY_AUTO

[siva9999]

i have used "BLE_GAP_PHY_AUTO" in scanner code

actually it should scan "phy coded" and "non phy coded" aid values .

but in my case getting i was getting both "phy coded" and "non phy coded" values.

issue is getting garbage aid values for phy coded values .

can anyone please help me regarding this.

best regards

siva.

Hi Siva,

 

but in my case getting i was getting both "phy coded" and "non phy coded" values.

issue is getting garbage aid values for phy coded values .

 Could you please be more specific to which events/Calls you ar egetting garbage values? Some code snippets of your use case would also help solving this issue faster.

totally i have 3 devices with me,in that two will advertise and one will scan

one device  is BLE_GAP_PHY_CODED for advertise

second device is BLE_GAP_PHY_1MBPS for advertise

third device  is BLE_GAP_PHY_AUTO for scanning

from scanning i can able receive both advertising data,but getting constant garbage uuid values for BLE_GAP_PHY_CODED .

Have you set the extended bit to 1 in the scan parameters?

[siva9999]

yes

static ble_gap_scan_params_t m_scan_param2 = /**< Scan parameters requested for scanning and connection. */
{
.extended = 1,
.active = 0x01,
.interval = SCAN_INTERVAL,
.window = SCAN_WINDOW,
.timeout = SCAN_DURATION,
.scan_phys = BLE_GAP_PHY_AUTO,
.filter_policy = BLE_GAP_SCAN_FP_ACCEPT_ALL,
};

OK, I misunderstood your setup. You cannot setup the scanner to scan on two different PHY as there is onlyone radio that can be configured to listen to one PHY. What you can do is to scan on one PHY for certain time and then stop that scanner and  reconfigure the scanner to scan on a different PHY after a timeout.

in my case 

if i use BLE_GAP_PHY_AUTO (or)  BLE_GAP_PHY_1MBPS  on scanner code.

it reading both phycoded and non-phycoded values .

so how to avoid phycoded garbage values ,can u please help me regarding this.

(expected results- it should not scan phycoded values)

best regards.
