Dfu hangs on "Enabling DFU Mode"

[vngo15]

We are trying to implement the dfu update on one of our devices. During our testing phase, we discovered that the dfu state sometime got stuck on the "Enabling DFU Mode." We had tried the following:

• Aborting the update after it gets stuck which doesn't do anything
• Manually canceling the peripheral connection and retrying with new Service Initiator and Service Controller which gets stuck in the same place

The only thing that seems to help is restarting the app and/or the device

Here is our code for starting the firmware update process:

let firmware = DFUFirmware(urlToZipFile: url)
let initiator = DFUServiceInitiator().with(firmware: firmware)
initiator.alternativeAdvertisingNameEnabled = false
initiator.disableResume = true
initiator.dataObjectPreparationDelay = 0.4
     
initiator.logger = self
initiator.delegate = self
initiator.progressDelegate = self
            
self.serviceController = initiator.start(target: pairedDevice.peripheral)

Successful DFU update log:

Any pointers would be super helpful

After writing 0x01 the device should reply with an indication with value 0x200101 and restart in bootloader mode. The library is waiting for the reply and disconnection event.
Please, check why that never happens in the device side. Perhaps you need to restart Bluetooth, as the handle numbers may be cached, before doing the update?
