BLE_GAP_EVT_CONNECTED event is not triggered

Hi all,

I have checked in Nordic Devzone for this query but no luck in finding solution for my query.

I am using nrf52832 and configured as central and peripheral.

my device will scan and store peer address in flash and then connect to stored address later.

when i connect to peer address using sd_ble_gap_connect it returns NRF_SUUCESS but BLE_GAP_EVT_CONNECTED  is not triggered.

this issue occurs only for some peripherals and some peripheral i can able to connect and it triggers event as well.

tested with one of the example code: when i try to connect  peripheral  device programmed with ble_app_uart code this issue occurs where  BLE_GAP_EVT_CONNECTED  is not triggered.

but the same peripheral connects successfully through my Android phone.

i am unable understand what is the issue.

Please guide...
