How to enable Jlink for custom board for nRF52832 DK

[Reshmi Marimganti]

I am using nRF52832 DK. I have connected our custom board using Debug out and loading code is successful for custom board. I loaded radio_test code. Now I want to test the radio parameters. For that any settings required on the DK board to enable Jlink for custom board?????? In my system Jlink isi detected in com ports, but I am not getting Radio test in terminal. Please provide any settings required to enable Jlink for custom board.

Thanks in Advance.

Kristin, Any solder bridges settings do I need to change??

No, there is no solder bridges that has to be changed. When the external PCB is powered, the nRF52-DK will use P19 (Debug out) for programming instead of programming the chip on the DK. You can read more in the nRF52-DK user guide.

Kristin, I've configured to other pins, whatever pins I can take out and configured those pins for UART. Now my UART is working. I am facing another problem. Please look into this query...

Req: from the cap-sense board, different tap will be done by user (like 2 times tap, 3 three times tap etc). so the Bluetooth board (nrf52) will receive these taps as interrupt connected to a gpio configured from cap-sense board.

Profile Used in Bluetooth board: Proximity .

For the requirement stated,

1. firstly, i have added the interrupt functionality (pin_change_int code) into Proximity profile for checking the no of tap received through the gpio as interrupt.

2. secondly, when the tap is made from cap-sense side, the Bluetooth board will read the tap through the gpio assigned as interrupt.

Bluetooth board will to do fast adv , slow adv and goes to sleep (separate function buttons_led_init is there in Proximity code), but when interrupt functionality is added to the proximity profile, Bluetooth device is not going to sleep. so what change in code should be done in order avoid this conflict.

REQ: when both mobile and Bluetooth device is connected, character should be sent from Bluetooth device to mobile for doing some functionality in mobile side.

Action Taken :

I have used sd_ble_gatts_hvx() function for sending the character from device to mobile as below,

memset(&params, 0, sizeof(params));
params.type = BLE_GATT_HVX_NOTIFICATION;
params.handle = p_char_send.char_handles.value_handle;
params.p_data = data_to_send;
params.p_len = &len;
params.offset = 0;

err_code = ble_ias_c_send_alert_level(&m_ias_c, two_press);

but its not working for me. so, what change i have to do in in order to send character or number from device to mobile?.
