BLE AoA and nRF 802.15.4 Driver sharing Radio

[zrivard]

Hi,

I am trying to get both the 802.15.4 stack and the BLE AoA stacks to run concurrently on an nRF52833.

Looking at the documentation here, it appears that it should be possible to do this using MPSL.

My setup:

• nRF SDK v2.5.3
• nRF52833DK_nRF52833

I started with a pristine copy of the peripheral_uart sample to verify my timeslot implemetation. I added the following KCONFIGs to prj.conf to allow it to receive 802.15.4 packets.

CONFIG_NRF_802154_RADIO_DRIVER=y
CONFIG_NRF_802154_SL=y
CONFIG_NRF_802154_TEMPERATURE_UPDATE=n

CONFIG_MPSL=y
CONFIG_MPSL_TIMESLOT_SESSION_COUNT=6
CONFIG_MPSL_WORK_STACK_SIZE=2048

With this setup, I am able to use the peripheral_uart project as expected, while also being able to see incoming 802.15.4 packets.

I then moved to a pristine copy of the direction_finding_connectionless_rx project. Without making any modifications to it, I was able to receive BLE AoA packets from my transmitter (as expected). After adding the above KCONFIGs to this direction_finding_connectionless_rx project, I am unable to begin BLE scanning.

I was able to set the BT debug level to DBG to get a more detailed log of events, which I have attached below for reference.

Do you have any recommendations for using MPSL to use both BLE AoA Rx as well as 802.15.4 Rx?

Thank you,

Zach

[Marte Myrvold]

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

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

[Marte Myrvold]

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
