[quote user="swz_nordic5340"]the nrf52833 board has a special cpnnector.it is MM8130-2600.[/quote]

Yes, that is an SWF connector. As you got the SiLab antenna to work I assume you use a cable with an SWF connector as well?

[quote user="swz_nordic5340"]there is no output about the connection with ti board[/quote]

Not about it, I am asking if there is a change in what is being outputted with it connected. With an SWF connector the signal should be routed to the antenna, forcing you not to use the internal one.

[quote user="swz_nordic5340"]i don't build my project and flash the procedure to my boards.so i don't have the iq sample or what in Rx is mentioned.[/quote]

Could you expand on this? I am not sure if I understand what you mean here.

Besides this,the ti board connector is here.

but nordic connector is another kind.it is here.

i also buy a new turn connetor to link both diffrent board.can you tell me the more information about this connector?

I take your suggetion.I study the connector of both nrf52833 board and ti AOA antennan array board.i find some problem.because the nrf52833 board has a special cpnnector.it is MM8130-2600.In the most sitution,there is no output about the connection with ti board.i link the board .it has success in work stute,i measure the level of ti board.it has 3.3 V level in.as you see the picture,you can see the how ti board status.

the next is my connector if both boards.

the next is nrf52833 board the conentor what you see is here.you can make a link to your ti board .what you do and you find you can tell me.

I think my exeriment have some insufficient.sp i don't have done my all work.

i don't build my project and flash the procedure to my boards.so i don't have the iq sample or what in Rx is mentioned.

thanks for your advice,i decide that i buy an new connector.i wiil try this after spme days.

Elfving — Mon, 02 May 2022 07:25:17 GMT

Are you sure you are using an SWF connector and not an U.FL? And are you sure the antenna is securely connected? Are you seeing any difference in the log in the terminal with the antenna disconnected?

[quote user="swz_nordic5340"]do you have a try[/quote]

Unfortunately I do not have a TI Boostxl Antenna on hand, but it should work with our boards. Here is another case in which a customer made this work, maybe taking a look there will help.

yes,i get the iq sample in silab 16 antenna array.I also prove that my antenna pattern have realized.i cna control the 16 antennae.but i can't get the iq sample from 6 antenna array of TI.I get the part output of Rx.As you can see,i only get the "Waiting for periodic sync lost..." in my problem.i don't find this problem.do you have a try?look forward to your reply.

[quote user="swz_nordic5340"]

I mean that i can control the 16 antenna array,but think the 6 antenna array are less than 16 antenna array,so i only change the configuration about antenna partterms.i only keep a some of 6 antenna array configuration.but it does't work well.i can't get the full output of Rx .you can see that in my problem.

[/quote]

And by that, do you mean that you got the desired result using a Silab antenna?

If not, note that the I/Q data itself won't be printed out in the terminal by default, if that was the result you were looking for?

[quote user="swz_nordic5340"]yes,i try yir method[/quote]

I assume you've not only commented out {0x4, 0x2, 0x1}, but also added the pattern {0xC,0xA,0x9}. Note that you need a minimum of 3 antennas in the pattern.

I also assume the log you provided from RX simply continues like that indefinitely? It might not always be as quick to find the periodic advertising and get the CTE. Below is the log I've got from trying it just now.

[quote user="swz_nordic5340"].but it have a error.i change the configuration,it have no output.[/quote]

So you are not only not getting the CTE now, now it additionally doesn't have an output? An by that, do you mean the log from the RX (locator)? Are you getting an output if you switch to the Silab16 antenna array?

/*切换顺序，A1.1,A1.2,A1.3  3根天线*/
/*static const uint8_t ant_patterns[] = { 0x4, 0x2, 0x1 };*/

i can't get the iq samples.

I see.

Could you try the antenna pattern: ant_patterns[] = {0xC,0xA,0x9}; ?

Hello Shu, and sorry about the delay

Are you able to find the periodic advertising without using the antenna? Have you edited anything in the Direction Finding samples from the SDK besides the switching pattern?

By the way: The TI Boostxl Antenna should work with our Direction Finding samples, but you may need to trim the switch point to compensate for different delays in the switches. This is described in the nWP036 - Direction Finding.

[quote user=""]

on the basis of silab 16 antenna array,i modify some configurations about this.

Could you expand a bit on what you mean by this?
