Get device name in advertise data

[Marchel Ace]

HI, i would like to get device name and print to uart, but when i try to print the device name i got error character.

Here my snipet code and uart result

    const ble_gap_evt_adv_report_t *p_adv_report = &p_ble_evt->evt.gap_evt.params.adv_report;
    const ble_data_t *data = &p_adv_report->data;
    
    uint8_t *device_name = ble_advdata_parse(data->p_data, data->len, BLE_GAP_AD_TYPE_COMPLETE_LOCAL_NAME);
    int8_t report = p_ble_evt->evt.gap_evt.params.adv_report.rssi;

    if(data->len == 0)
    {
      
    }
    else{
      printf("%d, %s \r\n",report,device_name);  
    }

Hi Marchel

What terminal are you using to print this data? What speed (bps) are you using (this should be 115200 when using our SDK)? Please try using the PuTTY terminal and the correct bps to see if you get the same results there.

Best regards,

Simon

Hi Marchel

What is the device name you're trying to print? Does it include any "forbidden" characters in the ASCII alphabet or what? Also, what SDK example and SDK version are you using? Are you using a development kit or a custom board?

Best regards,

Simon

Iam Trying to print Device named Pasien, not included forbidden characters just "Pasien" and i use SDK 15.3 with ble_peripheral blinky as a example. iam using NRF52840-DK before i deploy to 52840 Dongle. 

Thanks for replay me simon

Hi Marchel 

Have you enabled flow control in your application? If not,  that is likely what is causing these "random" errors. You can enable the flow control by adding the following line to your uart_init() function:

.flow_control = APP_UART_FLOW_CONTROL_ENABLED

Best regards,

Simon
