BLE AoA and nRF 802.15.4 Driver sharing Radio

Hi Zach,

There are no current plans for this.
Note that protocols sharing one radio will have bandwidth restrictions on both protocols, so even if the software supports it, it may not work in a real-life application. AoA RX usually needs more or less full access to the radio for good performance, so we only use it with low-bandwidth Bluetooth connections when we enable the AoA/AoD RX.

Best regards,
Marte

Thanks Marte,

That is unfortunate that the two implementations are incompatible with each other.

Do you know if there are any plans to bring AoA Rx into the SoftDevice controller to allow them to work together?

Thanks,

Zach

Hi Zach,

It is not possible to use Bluetooth LE AoA RX together with 802.15.4. AoA RX is only supported by the Zephyr Controller and not the SoftDevice Controller, while MPSL only supports the SoftDevice Controller. Without MPSL and timeslots, you will not be able to use the 802.15.4 driver together with Bluetooth LE.

Best regards,
Marte
