Multi connection with NUS

[Akshat]

Hi,

I am new to the BLE and Soft device stack, I am working on Multi link peripheral example with SDK version 9.0. I have flashed the S110_nRF51_8.0.0 into the nRF51-DK using nRF go Studio.

I want a peripheral with multiple link and should use NUC service for communication. I have flashed the application in the dev borad. In the Master control application it is showing the NUC service but I am not able to send/receive the data.

One more thing, my application int is look like:

int main(void)
{
    uint32_t err_code;
    bool erase_bonds;
    uint8_t  start_string[] = START_STRING;

    // Initialize.
    APP_TIMER_INIT(APP_TIMER_PRESCALER, APP_TIMER_MAX_TIMERS,                      APP_TIMER_OP_QUEUE_SIZE, NULL);
    uart_init();
    buttons_leds_init(&erase_bonds);
    ble_stack_init();
    device_manager_init(erase_bonds);
    gap_params_init();
    services_init();
    advertising_init();
    //conn_params_init();

    printf("%s",start_string);
    err_code = ble_advertising_start(BLE_ADV_MODE_FAST);
    APP_ERROR_CHECK(err_code);

    for (;;)
    {
        power_manage();
    }
}

Please help me to get out of the problem.

Thanks.

I'm assuming you have got the unmodified ble_app_uart working. Following it should work. Have you tried to use the debugger? If you set a breakpoint in ble_nus_string_send(), do you hit if when you try to send to MCP? If you set a breakpoint in on BLE_GATTS_EVT_WRITE in ble_nus_on_ble_evt(), do you hit it if when you try to send from MCP?

Hi Petter,

Thanks for your response. I got the NUS working with the mobile device. But the problem is that I am not able to connect multiple
mobile device with the module. When i connect with the single mobile, module is not able to advertise so the other mobile device is not able to connect. Can you please tell me how to connect multiple clients with the peripheral device ?

Thanks
