uart + twi sensor problem in received data

[ps_anu]

hi....

i am using nrf52382 .. segger 15.2version 

here i have attached two programs ble_uart and twi sensor ...  its working fine  but data is received over ble_uart app .. 

see the pic below

why i am getting the data like this ... i am reading the temperature sensor data

Can you post the code where you pass the sensor data to nus?

[ps_anu]

see the code below

static void read_sensor_data()
{
    m_xfer_done = false;
    uint16_t length1;
 char str[80];
       length1 = sprintf(str,"%d", m_sample);
      NRF_LOG_INFO("tempstr = %s  \r\n",str);
  nrf_drv_twi_rx(&m_twi, LM75B_ADDR, &m_sample, sizeof(m_sample));
  ble_nus_data_send(&m_nus,str,sizeof(m_sample), m_conn_handle);
     NRF_LOG_INFO("temp = %5d  \r\n", m_sample);
     NRF_LOG_INFO("Data send...");
        NRF_LOG_FLUSH();
}

You need to check the error code returned from your call to ble_nus_data_send(). It could be that you are filling the notification buffer, but you do not catch that since the return code is ignored.

Hi,

please could you post your complete code, not just this part of it? I would also like to implement some sensor to ble_app_uart, but don´t know how.

thank you
