Coexistence of Thread/Matter (SSED) and BLE (PAwR) on nRF54L15

Hi Gilbert,

Just confirmed with the team.. It should work. BLE always has priority and occupies the radio when there is some BLE event, and Thread/15.4 takes whatever is left. So it is advised to make sure not to spend too much time on the radio on BLE.

Could you provide some information on the radio pattern on BLE (like how long the packets are, how frequent etc.)?

Regards,

Swathy

Thanks so far - would be great if you could get any additional information.

Hi Gilbert,

Your assumptions are more or less correct.. nRF54L15 can run Matter over Thread and BLE concurrently on a single SoC using the multiprotocol (System‑on‑Chip) design. Refer: https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/protocols/matter/overview/integration.html#matter_platform_designs_system-on-chip_multiprotocol The radio time‑sharing is handled by the Multiprotocol Service Layer (MPSL). There have been discussions regarding this on Devzone, like this one: Is it possible that running Matter_light and BLE peripheral_uart at the same time? I am not sure about PAwR‑specific coexistence though.. I will have to check this internally and get back to you.
