S130 Starting advertise during peripheral connection

Yaroslav

I'm trying to start advertisement after establishing peripheral connection (on BLE_GAP_EVT_CONNECTED event) but called function sd_ble_gap_adv_start(...) returns NRF_ERROR_INVALID_STATE. But when I try to start advertisement after establishing central connection it works fine. Also when I start advertisement first then both (Peripheral/central) connections wok fine too. I use S130 SD, PCA10001 board and SDK 6.1.0. So, does S130 multi-role supports starting advertisement after peripheral connection?

    The current S130 is based on an earlier version of the S110 peripheral stack and it doesn't support advertising in connected mode. So if you already are connected as a peripheral, you will get the error that you see as you can only have one peripheral connection at the same time.

    In theory you would be able to do non-connectable advertising while in a peripheral state, but this functionality is not present in the current S130 version. You can still advertise when you have a central connection as this wouldn't affect the peripheral role.

    Looks like this issue is fixed in new (0.9) version of S130.
