How can i define memory length?

The code you've posted doesn't match with the log output. Anyway, to correct the reported errors, you should update the RAM start location and its size to the suggested values.

Adjustment of RAM and Flash memory

I just want to make a project like ble_app_uart.

I can use these two modüle separetly but when i run this code, i got error.

int main(){

uart_init();

log_init();

app_uart_put("z");

NRF_LOG_INFO("Program çalıştı ve bitti");

NRF_LOG_FLUSH();

for(;;){

idle_state_handle();

}

<warning> app: System reset
<info> app_timer: RTC: initialized.
<warning> nrf_sdh_ble: Insufficient RAM allocated for the SoftDevice.
<warning> nrf_sdh_ble: Change the RAM start location from 0x20001AE0 to 0x200022C8.

It is not possible to use the UART driver and the logger with the UART backend concurrently, as they cannot share the same UARTE instance. Instead, you can select the RTT logger backend to avoid this conflict. Note: To read RTT logs, you must have a J-Link debugger attached to your board.

No, I am not seeing any error.

e two problems right now. someone's device does nothing when I initialize the uart and log modules at the same time, it neither sends data from the log, nor sends data from the uart, nor does it advertise. but when I initiate these separately, I can send data.

i can't do advertising only when I activate the uart module, but I can send data via uart.

i can't debug either because uart and log don't work at the same time.

void poi_uart_init(){

ret_code_t err_code;

app_uart_comm_params_t const comm_params = {

.tx_pin_no = TX_PIN_NUMBER,

.rx_pin_no = RX_PIN_NUMBER,

.rts_pin_no = RTS_PIN_NUMBER,

.cts_pin_no = CTS_PIN_NUMBER,

.flow_control = APP_UART_FLOW_CONTROL_DISABLED,

.use_parity = false,

.baud_rate = NRF_UART_BAUDRATE_115200

};

APP_UART_FIFO_INIT(&comm_params,

UART_RX_BUF_SIZE,

UART_TX_BUF_SIZE,

NULL,

APP_IRQ_PRIORITY_LOWEST,

err_code);

APP_ERROR_CHECK(err_code);

}

It seems like you were able to get logging to work according to your other thread here: nrf log info with custom board . Are you seeing error messages in the log output?

It's been a long while I have not used it. I don't remember much. Have a look at the documentation link bellow.

how can i use nrf_log_info or debug function? should i write err_code or simple comment like "log modüle completed"

Sure you can. You need to configure it for uart instead of rtt

can i do that with nrf_log over uart? I do not ahve any debugger jlink

It is most likely your firmware crashed. You'll need to connect a debugger to find out where it crashes.
