Non-connectable advertising while connected or bonded in nRF Connect SDK

[Lukáš]

Hi, in the past, there has been discussed several times whether a peripheral can advertise even when it is already connected/bonded. It turned out it could be possible, however, most of these discussions were related to nRF5 SDK. 

• Is it possible to run non-connectable advertisements while connected or bonded in NCS? 
• If yes, could you please advise how? The API is not very clear to us and there are no samples for this.
• Do the Zephyr Controller or nRF BLE Controller differ in this manner?
• Is the Nordic Multi Protocol Service Layer (MPSL) in nrfxlib relevant to this case?

Our setup for testing is nRF91 as a host and nRF52 as a controller. Running the latest stable NCS.

I asked internally about this: "By default the connectable advertiser is resumed, so use the option ADV_OPT_ONE_TIME, and then just start the non-connectable advertiser once connected."

If you're  using ADV_OPT_ONE_TIME and you're starting the connectable advertising again this should be handled.

A colleague made an NCS example that demonstrates how to do nonconnectable advertising while connected.

Simon, thanks, that was fast! We will try to integrate it into our app.

It was made using NCS v1.3.0 by the way.
