- App is acting as BLE Peripheral
- The Bluetooth module is acting as BLE Central
- We have one "iPhone 12" with iOS 15.6.1.
- We have one "iPhone 13" and one "iPhone 13 Pro", both with iOS 16 beta 7.
- On previous stable versions of iOS 15 and below, pairing works fine.
- We see that a pairing request is sent from Central to Peripheral (app) on "iPhone 12" with iOS 15.6.1 and "iPhone 13" with iOS 16 beta 7.
- On one "iPhone 13 Pro", we don't get a pairing popup where as on iOS 15 we get the pairing popup. We looked at the bluetoothd logs and see that on iOS 16, it could be failing for following reasons:
default 23:06:40.830277+0530 bluetoothd Read fMapEnabled : 0
error 23:06:40.830359+0530 bluetoothd Denying connection attempt from device CC:C0:79:70:0D:2B. Is MAP enabled? Is MAP connected to some other device?
- sysdiagnose logs don't show any packets captured related to "ATT Receive" for iPhone 13 Pro where pairing fails. We want to understand what has changed in iOS 16 beta to cause this behaviour and if there is a way to fix this on the phone as upgrading the motorcycle ECU firmware would be a very time consuming process.
