High Sample Rate with ADC and SoftDevice of nRF52832

[song]

I am trying to sample the ADC every 8ms. During BLE transmission, the CPU will be blocked, therefore limiting the sampling frequency of the ADC?

According to me, that should not be a problem with provided sampling rate. Song, I think you are sampling ADC in blocking mode instead of non-blocking mode. "nrf_drv_saadc_buffer_convert" can be use to prepare ADC for sample in non-blocking mode and trigger sample by calling "nrf_drv_saadc_sample()" right after the conversion function.

You will redirected "NRF_DRV_SAADC_EVT_DONE" with this event, when ADC sampling is done. This process is handle by easyDMA rather to CPU. For continuous sampling, set two buffers for conversion and start sample it.
