[ps_anu]

how to send the data to ble_app_uart , i used this line 

  ret = ble_nus_data_send(&m_nus,"hwllo",25,m_conn_handle);
but i am not receiving any data in ble_app

Hi,

The USB port of the Dongle will not work with the ble_app_uart examples. You should use the USBD BLE UART Example instead, which implements the USB CDC ACM library for sending UART data over the USB port.

Best regards,

yes i used above example program only . i merged the usbd_ble_uart example with twi, saadc example. receiving the adc data only i am not getting the i2c values why ?

Most likely there is an error in your application. Are you checking error codes returned from all function calls? Is the issue you are seeing with transferring the I2C data over BLE/NUS, or are you having issues with reading the I2C device in general?

yes , it is working fine in general .. but not usb dongle
