Bluetooth 5.2 support for nrf52840

Question

Hello Nordic support, 
 I would like to confirm whether nrf52840 supports only Bluetooth 5.0 features or does it also support Bluetooth 5.2 features. If it supports Bluetooth 5.2, what features of 5.2 version are supported? 
 Thanks in advance, 
 Anusha

Hi Anusha 
 As of yet, the upper layer protocol is still under development by the Bluetooth SIG I believe, and the only new feature that devices are required to support to be regarded a BLE 5.2 certified product is Isochronous Channels, which the nRF52840 does support. However, the LE Power Control and Enhanced Attribute Protocol are optional features in Bluetooth 5.2. Check out this blog post for an overview of the new features in BLE 5.2. Our nRF52 series support the radio communication for LE Audio, but won't be able to run the LC3 Codec, which you will need a dedicated processor for. We recommend the nRF5340 which, with its dual processors is able to run both the radio and the LC3 Codec. 
 Last year, we (in partnership with Packetcraft) launched an LE Audio Evaluation platform, using the nRF52832 for radio communication, alongside the CS47L35 smart codec to provide an evaluation platform for LE Audio. More details here .

 Best regards,
