Is possible to use nRF52840 BLE/Thread Multiprotocol concurrently?

[MyeongjinKo]

Hi, I'm trying to use BLE/Thread Multiprotocol for BLE RSSI scanning and send values using Thread, is it possible to use BLE and Thread(FTD) concurrently with out time-slice? I'll just use BLE protocol for RSSI scanning not for connection.

Hi,

nRF52840 use the same radio for BLE and Thread, and it can only be used for one protocol at a time. You have to either switch between the two protocols (switched multiprotocol) or use time slicing (dynamic multiprotocol). With time slicing the device will be able to maintain the connections with the different protocols, but radio operations cannot happen simultaneously, which is why the radio hardware must be time sliced between the protocols.

Best regards,
