Hi,

Hi, thanks for your help, I did not make any change but now the NUS example seems to be working.

Hi Sid,

What did you mean by "there is no data coming from the dev board" ?
Please upload the sniffer trace.

As I suggested, please step into the code and debug.
If you see the write command from the phone to the dev board, a write callback should arrive in bt_receive_cb()

Hello Hung Bui (hungbui), thank you for the reply.

I am using nRF Sniffer, I see data going from my phone to the dev. board, there is no data coming from the dev board.

Yes the UART connection is working, it is a virtual comm port via the JLInk OB.

No modifications have been made to the sample.

I have not tried any other sample.

Hi Sid Price,

I would suggest to use the nRF Sniffer to check if the phone actually sending any data to the nRF5 chip.

Have you verified that the UART connection is working properly ? I would suggest to try put a break point in bt_receive_cb() function to see if the callback is called when you send something from the phone.

Have you made any modification to the peripheral_uart sample ?
Have you tried to test with other sample , for example peripheral_lbs ?
