CC2640R2F-Q1: ANCS authentication

Hi,

we are working on the peripheral GATT client to receive the ANCS notification from iOS device.

when I read the apple design document, it says that to receive the notifications, BLE client must authenticate it self?

from document: "All these characteristics require authorization for access."

what does it mean here?

1. do we need to do the pairing with passkey (MITM) and bonding authentication where passkey is displyed on accessory and then entered in iOS device?

2. do we just need to perform pairing and bonding without MITM.

3. we can just have pairing and no bonding (without MITM)

What I want to understand is "is MITM and bonding are necessary for this authentication?" or simple pairing without MITM will work.

Hi Pawan,

I recommend you read through our software users guide on the selection of pairing method to best pick the pairing method that fits your requirements.

Hi Evan,

for me just works method with no bonding is best suited as i don't have any display for the passkeys.

But will it work for the ANCS?

Pawan,

Just works only gives you an unauthenticated connection. If you need authentication like ANCS requires, i recommend you look for a combination that works for your application that gives you an authenticated session per the table in Figure 58 of the link above. It depends on your IO Capabilities. I would use MITM yes.
