Does the SoC nRF52832 support Bluetooth 4.2? Or is there any other SoC which supports the same?
Both the nRF51 Series and the nRF52 Series have the required hardware to be compliant with Bluetooth 4.2.
SoftDevice S130 for the nRF51 Series is compliant with Bluetooth 4.2.
SoftDevice S132 for the nRF52 Series is compliant with Bluetooth 4.2, but this is an alpha release.
I believe your question is answered here.
