Hi,

I want to ask a question on Configuration Parameters, In Simplelink SDK project AoA_receiver, If location in the advertise data packet of the bytes contains pLocPktTab can be changed? How to change the Configuration Parameters whited to RF core. Thank you very much.

Hello,

It is not possible to change the tone location, currently we use the PDU, please refer to this link for more information.

David,
Thanl you for your help! I want to know that TIcompanty ID and packetID must be set at the third to the fifth bytes of PDU?
Best regards,

Hello Hue,

Yes and this is configured in AoA_open.

    // Set up table for locationing packet definition
    // Which packet Ids should the receiver match on?
    aoa->pLocPktTab[0] = params->pktId0 << 8 | params->pktId1;
    // 1 set of company IDs to match
    aoa->pLocPktTab[1] = 1;
    // Match Texas Instruments
    aoa->pLocPktTab[2] = COMPANY_ID_TEXAS_INSTRUMENTS;

In other words they need to match. And because this is part of the PDU it will not be distorted by the whitening filter.

Best regards,

David

Hi David，

Yes , Thank you for your reply. And let me make my question clearly: TI AOA advertising PDU is in the table below:

13	adv0	0x1E	adv Len
14	adv1	0xFF
15	adv2	0x0D	TI companyID	16bit
16	adv3	0x00
17	adv4	0x04	AoA packetID	8bit
18	adv5	0x00	padding	6 bytes
19	adv6	0x00
20	adv7	0x00
21	adv8	0x00
22	adv9	0x00
23	adv10	0x00
24	adv11	0xFF	DF signals	20 bytes
25	adv12	0xFF		begin at (1+4+6)byte
26	adv13	0xFF
27	adv14	0xFF
28	adv15	0xFF
29	adv16	0xFF
30	adv17	0xFF
31	adv18	0xFF
32	adv19	0xFF
33	adv20	0xFF
34	adv21	0xFF
35	adv22	0xFF
36	adv23	0xFF
37	adv24	0xFF
38	adv25	0xFF
39	adv26	0xFF
40	adv27	0xFF
41	adv28	0xFF
42	adv29	0xFF
43	adv30	0xFF

when the AOA_sender's advertising data change like this, how to change the AOA_receiver program。(three bytes was moved)

13	adv0	0x1E	adv Len
14	adv1	0xFF
15	Adv2	0x00
16	Adv3	0x00
17	Adv4	0x00
18	Adv5	0x0D	TI companyID	16bit
19	Adv6	0x00
20	Adv7	0x04	AoA packetID	8bit
21	Adv8	0x00
22	adv9	0x00
23	adv10	0x00
24	adv11	0xFF	DF signals	20 bytes
25	adv12	0xFF		begin at (1+4+6)byte
26	adv13	0xFF
27	adv14	0xFF
28	adv15	0xFF
29	adv16	0xFF
30	adv17	0xFF
31	adv18	0xFF
32	adv19	0xFF
33	adv20	0xFF
34	adv21	0xFF
35	adv22	0xFF
36	adv23	0xFF
37	adv24	0xFF
38	adv25	0xFF
39	adv26	0xFF
40	adv27	0xFF
41	adv28	0xFF
42	adv29	0xFF
43	adv30	0xFF

I want to get your help eagerly, look forward to your reply.

Hi Hue,

If that is really the case, you will need to compensate for those 3 extra bytes. This could be achieved by changing g_initialPeriod.

"The g_initialPeriod is delay for GPTimer. The reason for adding the delay is that when radio core notifies the application that an AoA packet is received, the actual tone has not arrived yet. Therefore, there is delay added to the timer start to ensure that the antenna only toggles when the tone arrives.

The delay number was found in lab measurement. However, this number should not be changed unless you want to start your antenna toggling later".

Just for our general knowledge, would you mind explaining how did you collect the previous data?

Thanks,

David
