DFU Passkey and Whitelist

[sbailes]

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.

That should not help at all, you should have the exact same behavior. The events from the SoftDevice are sent to ble_evt_dispatch() first, it forwards the events to on_ble_evt() and more. You cannot pair before you connect. It is not possible. If you want to send a security request after you have connected you can use the BLE_GAP_EVT_CONNECTED event. Please be aware that it is the central that actually decides if it want to respond to the security request from the peripheral, and send a pairing request.
