I cannot get AOA data in ncs2.4.0 sample: direction_finding_connectionless_rx

hardware: DK:
nrf52833dk_nrf52833

ncs:2.4.0

sample: direction_finding_connectionless_rx   

I cannot run into create_sync() after the scan_enable() is runed.

I can find many advertising package. 

[DEVICE]: 41:26:6F:32:02:01 (public), AD evt type 3, Tx Pwr: 127, RSSI -54 C:0 S:0 D:0 SR:0 E:0 Prim: LE 1M, Secn: No packets, Interval: 0x0000 (0 ms), SID: 255

 

but the interval always is 0. and SID always is 255.

I cannot find : success. Periodic sync established.

So, never run to receive CTE.

In the callback for scan : scan_recv().   the condition would never match.

if (!per_adv_found && info->interval != 0)  // so, the code in it would never run.

{

   per_sid = info->sid;   // never run

    k_sem_give();

}

what cause this?

how can I run to get the CTE ?   what requirement we need?

there is a device sending  AOA package always. this package can be received by other products.

thanks.

Direction Central and peripheral Works WELL!

but,    direction_finding_connectionless_tx & direction_finding_connectionless_rx  FAIL to get IQ samples.

after debug, I find the code stall at  k_sem_take(&sem_per_adv, K_FOREVER);

And that is also the case with the coax UFL cable connected?

[brook]

the DK works like this.

[Elfving]

Right. Do you have a coax UFL cable? I don't think it will connect without it inserted.

thanks, Elfving.

but, I think the coax cable make no difference.

for  in the sample of (central and peripheral ).  I did not use coax cable either.

P.S,   who give the interval and SID. the device advertising? 

thanks.
