Check BLE connection status

[AmiguelS]

Hello!

We're using SDK 12.3 on our application, and we're aware that the SDK is targeted to be event driven, meaning that our code should be the one keeping track of the connection status by using the propagate events.

However, the problem we're facing is that sometimes, when the scheduler queue becomes full, and because it is also being used for the SoftDevice, the code looses some SD events, loosing track of the connection status.

If the SD also kept track of the latest connection status, we were thinking about using a timer to periodically compare the tracked status with what the SD knows.

Is this approach viable/possible?

Thanks!

Hi,

Unfortunately, there are no API you can use to get the connection status directly. But you could e.g. use sd_ble_gap_adv_start() and check the return code. You will get NRF_ERROR_INVALID_STATE if you are already advertising or NRF_ERROR_CONN_COUNT if you are in a connection (and cannot start another advertiser). Not very elegant though, and it probably won't work in multilink applications.
