[quote userid="82185" url="~/f/nordic-q-a/64722/advertising-auto-restart"]why can the advertisement be stopped by the SoftDevice, but not started again automatically?[/quote]

Yes, the application needs to restart the advertising with sd_ble_gap_adv_start(). By doing this, we let the application decide if it wants to start the advertising again or not. This leaves the developers with better flexibility on how they want their application to behave.

[quote userid="82185" url="~/f/nordic-q-a/64722/advertising-auto-restart"]Also, what is the limit for central and peripheral connections with s130?[/quote]

The S130 SoftDevice can be configured with one connections as a Peripheral and up to eight connections as a Central.(link)

Note that with the S132/S140 SoftDevice for the nRF52-series you can have up to 20 links, freely configurable roles.

[quote userid="82185" url="~/f/nordic-q-a/64722/advertising-auto-restart"]What happens, when i try to start advertising, while a client is connected? I suppose i get some error regarding the client limit?[/quote]

If you have exceeded the maximum numbers of connections, you will get the NRF_ERROR_CONN_COUNT error, telling you that the limit of available connections has been reached; connectable advertiser cannot be started.
