How to use i2s to get raw data and transfer to smart phone via ble_uart_app?

Hi

I have been succeed test SDK15.0.0 i2s example and got UART data.

UART started.<CR><LF>
NRF_LOG_DEFAULT_BACKENDS_INIT started.<CR><LF>
NRF_LOG_DEFAULT_BACKENDS_INIT end.<CR><LF>
DEBUG:   1: OK<CR><LF>
DEBUG:   2: OK<CR><LF>

DEBUG:   4: OK<CR><LF>
DEBUG:   5: OK<CR><LF>
DEBUG:   6: OK<CR><LF>

But now, I need to know how to get i2s rx raw data...

I want to transfer it via ble_uart.

I want to save i2s raw data into RAM, and sent by ble_uart, again and again.

ps. ble_uart is ok for me.

Thanks

Hi

The data from the i2s transfer is stored into the rx buffer once the event handler is called. I recommend storing the data in Flash by using the FDS module. You can send the data over BLE by using the ble_nus_data_send function call. You should use the Ble template example in the SDK to merge the different modules together.
