Hi,
We are part of the Mfi Program, and use traditional Blueooth for our development
We are having some trouble on connectivity on traditional Bluetooth when connection to our accessory.v
Does Wifi tuned on/off have some impact on Bluetooth connection to the accessory? We are seeing some differences in behaviour when Bluetooth is trying to connect while the wifi is tunred on or off. I saw somewhere that when bluetooth is in scanning mode, it would use the wifi antenna in the iOS device. Is this correct?
FYI, I've had similar problems with BLE: when BLE scanning is enabled, wifi access will often drop out almost completely. I can see the same problem when regular (non-LE) Bluetooth scanning is active, by pinging the iPad and then entering the system Bluetooth settings dialog; pings and packet loss shoot through the roof.
(This can sometimes be alleviated by switching Wifi channels, and using 5ghz wifi seems to eliminate the problem entirely, but that's not too helpful in practice. Average users aren't going to play around with their wifi configuration.)
I've only seen this when in active scanning mode, not merely when the system is trying to connect to a known peripheral in the background.
