Furthermore, nRF5 SDK 11 is not tested with nRF52832 Engineering A revision which is present on the PCA10036. There are however a few examples available <a href="https://devzone.nordicsemi.com/question/62712/nrf52-adc-sampling-multiple-signals/?answer=63400#post-id-63400">on this tread for PCA10036</a> together with nRF52 SDK 0.9.2. For a SAADC example that uses BLE, there is an <a href="https://github.com/NordicSemiconductor/nRF52-ADC-examples">example available here</a> for SDK 11.0.0 and PCA10040. The <a href="https://github.com/NordicSemiconductor/nRF52-ADC-examples/tree/master/saadc_low_power">saadc_low_power example</a> initializes the SAADC before sampling and unitializes the SAADC when done sampling.</p> <p>For compatibility of different ICs, SDKs and softdevices, look at the <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52/dita/nrf52/compatibility_matrix/ic_rev_sdk_sd_comp_matrix.html?cp=2_1_2">nRF52 compatibility matrix</a>.</p><div style="clear:both;"></div>
