In My customer board with nRF52840, run with example "ble_app_att_mtu_throughput", it can not scan any devices or being scanned by other centrol devices

[zxd]

[nRF5SDK15.2.0, KeilMDK, Windows 7]

the code runs ok in the customer board, and the print log as fallows:
[00:00:00.000,000] ble_scan: Adding filter on CPS_xxx name
[00:00:00.000,183] app: ATT MTU example started.
[00:00:00.000,183] app: Press button 3 on the board connected to the PC.
[00:00:00.000,183] app: Press button 4 on other board.

[00:00:00.000,274] app: Starting scanning.
[00:00:00.000,396] ble_scan: Scanning

but it sames that my board can not tx or rx any wireless signal, because I Cannot recieve any broadcasting infomation or scanning any BLE devices, where would the problem be?

besides: the code work well in the demo board.

Thanks.

Hi

Due to the Easter holiday you will have to expect a delay in replies, sorry for the inconvenience!

How does your matching network and antenna look? Could you please upload the gerber files to your project so I can have a look? If you don't want the files to be public, just tell me, and I will set this case to private. That way only you and Nordic engineers will be able to see the ticket.

Best regards and happy Easter,

Simon
