RE: Zephyr/nRF Connect SDK one peripheral with multiple central

Yes, I tried but it was not successful, probably because of other changes that I made.

After the rollback, I tried to do it again and for now, I can, at least, connect two devices. After the second connection bt_le_adv_start return "-61" error. But I realized that such behavior not correct and I need to pair devices and run advertise only when I need to create a new pair.

Actually starting of new advertise after connect starts working only after I add "CONFIG_BT_LL_SOFTDEVICE_DEFAULT=y" to the settings.

Thank you for your help.

Sample "peripheral_hids_mouse" implements such behavior.
And my solution could be found here https://github.com/Quard/nrf_ble_rolling_shutter_poc/tree/restart_advertising

Hi Vadym,

Have you advertise again after you get connected ?
By default the stack will stop advertising after getting connected.

So when you get connected you would need to call bt_le_adv_start() to start advertising again.
