DFU Passkey and Whitelist

Question

I am trying to use whitelisting and a passkey to add security for my application. So far I have the passkey set up so that it is working on the master control panel on PC, but for some reason it is not working on the iOS app. I also am not sure that I am implementing the whitelist correctly. I want to be able to bond to the device using a passkey, and then program OTA using the DFU service. I have attached my main.c file to look at. (I am using sd130 v.2 and SDK 11). 
 These messages just keep popping up in the log and repeating nonstop

I think you are using S130 2.0.0-7.alpha, together with SDK 11.0.0-2.alpha. I would recommend using S130 2.0.1, since this is a production release. Use this with SDK 11.0.0. It is available here . Under nRF5_SDK. 
 You are calling sd_ble_gap_authenticate() every time on_ble_evt(), which means that you send a security request to the central every time you get a BLE event from the SoftDevice. Remove it.
