RE: when use the DF of central and peripheral,i don't use the antenna array,but i set,there is no out put,what is this problem?

swz_nordic — Thu, 21 Apr 2022 02:52:07 GMT

ok,i try as you suggest.In the default setsetting,i can get the iq sample form my Tx.i only change the configuration about the antenna array.The antenna _num and antenna_partterns,because i use 16 antenna array.

i only chnage the overlay file in nrf52833dk_nrf52833.overlay and change some configuration in main.c file.

The overlay file have been changed as follow.

#endif /* CONFIG_BT_DF_CTE_RX_AOA */

but this problem i also meet in connection.so i think it is design problem.

because it can't more than 16 antennae,so i do some test about both design.

another problem in connectionless have err code -22.The link is here.

i wait for your solution abot this,because i can get what this problem is.Thanks for your reply.
