Hi, we have project AoA direction finding. Firstly we have nrf5340 dk kits. Also CoreHW ANT3 2x2 matrix antenna kit. I run the direction finding connectionless demo on nrf5340-dk. I did some changes on code.
static const uint8_t ant_patterns[] = {0x0, 0x4, 0xA, 0xE}; -> this new array of the antenna matrix.
dfe-antenna-num = <4>; -> number of antenna.
and lastly I added this code into the cte_recv_cv function.
for (int i = 0; i < report->sample_count; i++) {
if (report->sample_type == BT_DF_IQ_SAMPLE_8_BITS_INT) {
printf("IQ sample %d: I = %d, Q = %d, channel index = %d\n", i, report->sample[i].i, report->sample[i].q, my->ant_ids);
}
}
My serial output like this...
Q1: Am i configured right? Anything else for my antenna array.
Q2: I'm not sure this is normal IQ datas. So I want know which pins active while scanning. For example
CTE[0]: samples count 45, cte type AOA, slot durations: 2 [us], packet status CRC OK, RSSI -630, "first switch pin active".
I found some pins description in "radio_df.c" file but i couldnt access the pins. Do you help me how can i overcome this problem.
Q3: While i trying something on visual devicetree editor the screen shown below opened. But this were not on purpose so how can i access again this menu.
And my setup below
