@sbailes: It worked fine for me with MCP v3.10 could you try to update to the latest MCP version ? If the issue remain, please send us a sniffer trace.

I am using sd_ble_gap_authenticate() and it works properly on the iOS app (nRF Master Control Panel) but does not work on the Master Control Panel on the PC. Do you know why this may be happening? (Windows Master Control Panel 3.9.0.6)

Hi Alex,

You can request bonding from the peripheral (using sd_ble_gap_authenticate() ) but not all the phones support this (reject the request) for example iOS device won't accept that.

So you should let the phone trigger the bonding. To do that you need to use your app to do a read/write on an encrypted characteristic so that the phone will automatically start bonding. The MCP doesn't do read/write automatically because it's simply a generic app.

Another option is to add HID service to your device so that the phone treats it as a HID device, but this is not something I would recommend.
