Hi Amanda - we will try to implement coexistence with a 1-wire interface using the API hooks you indicated. Thank you!

Hi,

Radio notification can be used for driving BT_ACT line. Similar to PA/LNA below. However, I couldn't find an API/hook to defer BLE activity while WIFI_ACT is active so far.

I would suggest you contact your regional sales manager (RSM) for the request. If you don't have RSM's information, please fill out the form of Sales related questions.

Thanks for the reply, this is not an option in our case. Are there API hooks into the softdevice such that we could implement the interface ourselves? IE set up softdevice hooks to drive the BT_ACT line when there's radio activity, and defer activity when WIFI_ACT is detected as being high?

Hi,

Unfortunately, nRF5 SDK doesn't support wifi coexistence. Please upgrade to nRF Connect SDK.

Please be aware that the nRF5 SDK is in maintained mode. That means it won't be added any new features. I would suggest you start the project with nRF Connect SDK. See nRF Connect SDK and nRF5 SDK statement
