How to get thingy data on nRF52840?

[wanna]

Hi.

I want to get thingy's sensor data on nRF52840.

I found that 'ble_app_multi_link_multi_role' example, but there are only get button and led state.

By using that project, i wrote sd_ble_gattc_char_value_by_uuid_read funtion to get data. But i get NRF_ERROR_BUSY and NRF_ERROR_INVALID_PARAM errors.

Could you help me to get thingy's sensor data? Thank you for reading.

    ble_thingy_tes_c_evt_t ble_thingy_tes_c_evt;
    uint32_t err_code;

    ble_gattc_handle_range_t   t_range;
    t_range.start_handle=0x0001;
    t_range.end_handle=0xffff;

    ble_uuid_t t_uuid;
    t_uuid.type = THINGY_TES_UUID_SERVICE;
    t_uuid.uuid = THINGY_TES_UUID_TEMPERATURE_CHAR;
    
    ble_thingy_tes_c_evt.conn_handle                  =   p_ble_thingy_tes_c->conn_handle;
    err_code   =   sd_ble_gattc_char_value_by_uuid_read(p_ble_thingy_tes_c->conn_handle , &t_uuid, &t_range);

No worries. If you liked the demo code, would you mind upvoting Carl's answer? Thanks.

What is the purpose of getting the thingy data onto a nrF52xx? I can adopt the example to retrieve the motion data, but I need to store this data so that I can process later. What am I missing?

Thanks,

Hi Rasit,

In this demo, we wanted to transfer the Thingy sensor data over BLE to a nrf52 & connect the nRF52 to the cloud via an nrf91 kit. The nRF52 is connected to the 91 kit via serialization. Then, the data is visualized on a website.

Could you please open a new devzone question regarding your second question?

Hi Bjorn,

I think when I tested the demo, I answered the question myself. I guess, by properly formatting the output that comes over UART, one can capture them and process them later. Nevertheless, I'll open up another question to see the alternatives other than 91 kit to push the data up.
