iOS CoreBluetooth caches peripheral.name

[vladimircherevko]

Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used patch-package to patch react-native-ble-nitro@1.12.0 for the project I'm working on.

iOS CoreBluetooth caches peripheral.name from the first discovery. After the device is configured and starts advertising a new name, peripheral.name still returns the stale cached value. The fresh name is available in advertisementData[CBAdvertisementDataLocalNameKey], but it is only used as a fallback — so it never gets picked up.

Android does not have this issue because its scan API reads the name directly from the current advertisement packet.

Fix:
Swap the priority to prefer the live advertisement data over the cached value.

Here is the diff that solved my problem:
