Hello,
The modules are based in the TI WL1271/WL1273 - more information is available on the manufacturer's website once you click into the individual page for those modules.
Since these are older devices, please be aware that BLE & ANT cannot operate concurrently. If you need concurrent operation, your best option would be to use an N5 module, using the s310 SoftDevice, and add a 3rd party Wifi module if you require that functionality.
