S130 simultaneous scan & advertise problem

Konstantin K

I'm trying to implement a simultaneous broadcaster observer by calling ble_gap_adv_start() and sd_ble_gap_scan_start() and waiting for respective events.

If I call advertising start first and scan start second, everything works fine. However, if I call scan start first and advertising start second, ble_gap_adv_start() returns invalid state.

The reason I need to call advertising start second, is that I'm always scanning but advertising only when I scan something of interest.

Am I doing something wrong?

Thanks,

K

    Hi all,

    After some investigation I managed to reproduce and locate the problem and it turns out this is an issue within the SoftDevice. This issue has since been corrected and will be included with the next release of the S130 SoftDevice.

    It can be worked around by temporarily disabling scanning before starting advertising.

    Apologies for the inconvenience and thanks to Konstantin for the help debugging this.

    Regards,

    Carles
