add ble_nus to buttonless app

[Stas]

I tried to add ble_nus service to buttonless app (sdk 14). Keil doen't raise any errors and compiled project, but app is not work actuall in NRF_LOG I can see these messages

0> nrf_sdh_ble: RAM start should be adjusted to 0x20002760.
0> nrf_sdh_ble: RAM size should be adjusted to 0xD8A0. 0> app: Fatalapp: Fatal

I tried copy IRAM settings from app_uart example to my app but it wasn't work

I've also tried debugging

1. I set breakpoint

2. Change Keil options for debugging

3. Compiled, Programm project (OTA DFU)

4. Start debug session (Ctrl + F5) and get this window

You need to change the IRAM settings to the values in NRF_LOG.

I believe in Keil, it is under Options for Target.

Thanks Now I have another issue in NRF_LOG

app: Setting vector table to bootloader: 0x00078000

app: Setting vector table to main app: 0x00023000

app: Fatal

Have you tried debugging? When you get the Fatal error it usually means that you end up in an endless while loop in an error handler. There you can get an error code and the line number and filename showing where the error originates.

I've tried it, in Debug mode I got break (as I understand) on line 248

  return (memcmp(p_addr1->addr, p_addr2->addr, BLE_GAP_ADDR_LEN) == 0);

in file id_manager.c I changed start topic plc check it out.

Solved. I increase uuid count to 2

#define NRF_SDH_BLE_VS_UUID_COUNT 2

after that again change IRAM to what NRF_LOG me said (start 0x20002100, size 0xDF00). And now I can see UART service in NRF connect
