Control of PTA Signals

[OKA_T.T]

SoC: nRF52832 or nRF54L15
SDK: nRF Connect SDK v3.2.0

We are considering controlling coexistence via PTA signals when operating a third-party Wi-Fi device together with nRF52832 or nRF54L15.

Is there a dedicated PTA library available for BLE in the nRF Connect SDK?

Alternatively, to implement PTA control, is it necessary to develop a custom solution using the MPSL CX API together with Generic three-wire coexistence?

We would appreciate your advice on this matter.

Best regards,

Hi

Please check out the documentation on Wi-Fi coexistence module here https://docs.nordicsemi.com/bundle/ncs-latest/page/nrfxlib/nrf_802154/doc/wifi_coex_module.html 

You can also check out the Wi-Fi BLE coexistence sample here, but I guess you're not using the nRF70 companion IC as the Wi-Fi device here: https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/samples/wifi/ble_coex/README.html 

Best regards,

Thank you for sharing the documentation.

We will review the Wi-Fi coexistence module documentation as well as the BLE coexistence sample.

If you have any additional recommendations or best practices regarding PTA control or coexistence implementation when using Wi-Fi devices from other manufacturers, we would greatly appreciate your advice.

Best regards,
