Samsung bought what was advertised as mobile handset business after CSR failed to spot that combo BT/Wifi chips were the future and threw away their lead. Qualcomm got the rest a few years later.
("what was advertised as" because there wasn't really a differentiation in the R&D bits, so there was a somewhat arbitrary split and hasty redacting of repos given to Samsung to avoid names of other customers in comments).
Samsung's phone division and electronic parts division aren't the same thing, so there was no guarantee that the phones would buy the Bluetooth/Wifi from their new acquisition, although I hear they did eventually.
