RE: Transmitting data from nRF52832 to smart phone using ble_app_uart example

I must say that the documentation, naming, and comments in the NUS example could be a lot clearer in distinguishing what is the actual, physical hardware UART and what is the "emulated" device over-the-air.

To be fair, it doesn't help that the word "peripheral" is used in two senses - there's "peripheral" in the Bluetooth sense, and also "peripheral" in the microcontroller hardware sense!

Hi,

There is no point in going through app_uart/uart_event_handle, this is for handling data from the hardware UART peripheral. What you should do is to add your data to a buffer in your spi_event_handler and pass this to ble_nus_data_send() to send the data on BLE.

Best regards,
