How to send SAADC Double Buffer through BLE?

[ENENER]

Hi

I'm using nrf52 DK with SDK V17.0.0

Currently, I'm using Single Buffer to send Data through BLE.

However, I want to use Double Buffer instead of using Single Buffer.

But, I have no idea about using Double Buffer.

    err_code = nrf_drv_saadc_buffer_convert(m_buffer_pool[0],SAADC_SAMPLES_IN_BUFFER);
    APP_ERROR_CHECK(err_code);   
    err_code = nrf_drv_saadc_buffer_convert(m_buffer_pool[1],SAADC_SAMPLES_IN_BUFFER);
    APP_ERROR_CHECK(err_code);

I understood this code(in saadc_init())means Using Double Buffer.

But, how to send Data through BLE in saadc_callback() function??

Thanks.

Hi,

This thread explains double buffering pretty good.

Sending SAADC data over BLE with double buffering has been implemented in this example.
