52833 LONG RANGE UART_APP_BLE Peripherals

[lpcy1991]

I get long range demo code for 52840 on the web:

long_range_demo_15.2

and modify the code to test the 52833 long range feature;

52833 long range peripheral demo.zip

MAINLY code:

static void advertising_init(void)
{
    uint32_t               err_code;
    ble_advertising_init_t init;

    memset(&init, 0, sizeof(init));

    init.advdata.name_type          = BLE_ADVDATA_FULL_NAME;
    init.advdata.include_appearance = false;
+    init.advdata.flags              = BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE;//BLE_GAP_ADV_FLAGS_LE_ONLY_LIMITED_DISC_MODE

    init.srdata.uuids_complete.uuid_cnt = sizeof(m_adv_uuids) / sizeof(m_adv_uuids[0]);
    init.srdata.uuids_complete.p_uuids  = m_adv_uuids;

    init.config.ble_adv_fast_enabled  = true;
    init.config.ble_adv_fast_interval = APP_ADV_INTERVAL;
    init.config.ble_adv_fast_timeout  = APP_ADV_DURATION;
+    init.config.ble_adv_primary_phy   = BLE_GAP_PHY_CODED;
+    init.config.ble_adv_secondary_phy = BLE_GAP_PHY_CODED;
+    init.config.ble_adv_extended_enabled  = true;
    init.evt_handler = on_adv_evt;

    err_code = ble_advertising_init(&m_advertising, &init);
    APP_ERROR_CHECK(err_code);

    ble_advertising_conn_cfg_tag_set(&m_advertising, APP_BLE_CONN_CFG_TAG);
}

*******************
    // Copy advertising data.
    if (!p_advertising->initialized)
    {
        p_advertising->adv_handle = BLE_GAP_ADV_SET_HANDLE_NOT_SET;
    }
    p_advertising->adv_data.adv_data.p_data = p_advertising->enc_advdata[0];
    p_advertising->adv_data.adv_data.len = adv_set_data_size_max_get(p_advertising);

    ret = ble_advdata_encode(&p_init->advdata, p_advertising->enc_advdata[0], &p_advertising->adv_data.adv_data.len);
    VERIFY_SUCCESS(ret);

+    p_advertising->adv_data.scan_rsp_data.p_data = NULL;
+    p_advertising->adv_data.scan_rsp_data.len = 0;

-//    p_advertising->adv_data.scan_rsp_data.p_data = p_advertising->enc_scan_rsp_data[0];
-//    p_advertising->adv_data.scan_rsp_data.len = adv_set_data_size_max_get(p_advertising);

-//    ret = ble_advdata_encode(&p_init->srdata,
-//                              p_advertising->adv_data.scan_rsp_data.p_data,
-//                             &p_advertising->adv_data.scan_rsp_data.len);
-//    VERIFY_SUCCESS(ret);

My question is: WHY IT cannot be connected to the long-range-DK 52840? (THE led1 is always flicking!!)

WHAT IS THE PROBLEM FOR THE LONG RANGE TEST ON 52833 DK？？？？

Hi

I think this is due to converting an nRF52840 project to run on an nRF52833 might cause problems as the two chips have different RAM and Flash sizes.

By inserting just the main file from the long-range demo for nRF52840 into the already existing pca10100 ble_app_uart project you should be able to run it successfully. If you're still having trouble, I think you'll have to debug the project to find out what is going on.

Best regards,

Simon

Yes, you are right!,

There might be some problems when downloading the demo code into the NRF52833, however, i still cannot find out the problem;

I have anothere NRF52840 DK, and test the long range feature successfully. 

Thank you for your advertise!

Hi

Glad you got it working with two nRF52840 DKs. Now, what trouble are you having with the nRF52833 project exactly?

Best regards,

As described in my question, after modified the ble_app_uart_pca10056 to run on the pca10100 DK, it doesn't work acturally. nRF52833 board cannot connect to the nRF52840,

you have suggested me to debug the code. because I am new to this DK, I cannot find the problem why it cannot work.

There may have some problems caused by the different RAM and FLASH size, which i cannot find out.

If you could ,could you pls provide me a demo code of ble_app_uart_peripheral for PCA10100 board?

There are very less demo code for the PCA10100 board, it makes some diffculties to develop project on this chip.

Hi

By adding your main code from the working PCA10056 version of the project to the already existing pca10100 ble_app_uart example you should get a working example for the NRF52833 DK, as I don't think anything but the main.c file was changed in the example you've got.

Best regards,

Simon
