nRF52840-DK can't receive my product bluetooth broadcast signal

[Ming78]

nRF52840-DK  2pcs, one TX broadcast signal software, one RX software. RX can receive TX.

My nRF52840 product 2pcs, one TX broadcast signal software, one RX software. RX can receive TX.

==============================================

nRF52840-DK 1pcs， My nRF52840 product 1pcs，the same TX software and RX software.

if nRF52840-DK is TX broadcast signal software, my nRF52840 product can receive the signal.

if my nRF52840 product is TX broadcast signal software, the nRF52840-DK can not receive the signal.

why ? where is the matter ? how to debug ?

Thanks.

Hi,

I checked the crystal oscillator, it absolutely same with the 52840 DK.

Please check the attachment as my PCB and SCH document.

Any advice is welcome.
