No Auto Connect in Slow Advertisement Mode for nrf51, using SDK11, S130

[alikob]

I am seeing some behavior in BLE advertisement mode , that I would like to get feedback from expert in this forum. I am using modified Keyboard HID example, using nrf51 BLE and SDK11/S130 softdevice. Here is what I am seeing , after a successful pair and bond to an iOS iPhone I can auto connect to iPhone after a disconnect, with no issues, as long as I am in FAST ADV mode, but when BLE goes to SLOW ADV, I cannot auto connect anymore, unless if I reset my in BLE target. I also modify the advertising_init() 

ble_adv_modes_config_t options =    {       

BLE_ADV_WHITELIST_DISABLED,       

BLE_ADV_DIRECTED_DISABLED,       

BLE_ADV_DIRECTED_SLOW_DISABLED, 0,0,       

BLE_ADV_FAST_ENABLED, APP_ADV_FAST_INTERVAL, APP_ADV_FAST_TIMEOUT,       

BLE_ADV_SLOW_ENABLED, APP_ADV_SLOW_INTERVAL, APP_ADV_SLOW_TIMEOUT    }; 

I am not sure if any of changes I did causes this behavior.  Thanks,

Hi.

I am using modified Keyboard HID example

Maybe you could elaborate on which modifications you have made?

I also modify the advertising_init() 

Could you also post the advertising_init() code that you are using?
Note that if you don't want to share code in a public thread, we can turn the thread private.
