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?
