I have implement printer in my iOS Product "ZD420", since it was working quite fine but as a change my device in iOS 16 the printer is unable to discover, however same printer is able to discover in earlier than 16 versions,
Anyone find this issue please let know the solution, either iOs version or SDK needs to be updated

For security reasons, iOS doesn't allow its apps to search or discover the Bluetooth Classic devices, unless they are Bluetooth Low Energy devices. For Bluetooth Classic printers, a user has to first pair and connect to a printer via the iOS device's Bluetooth setting. It could be that the iOS 16 device has not paired with the ZD420 before, therefore, the discovery method cannot detect the printer. Try to pair with the ZD420 printer first, then run the app to call the discovery method.
