Plugin version: 6.1.0
Flutter version: 3.10.4 • channel stable

I can update the firmware using nRF iOS app but not with my Flutter iOS app.

In nRF iOS app I had to set the following parameters to successfully do the DFU:

  • Allow Resuming DFU: true
  • PRN(s): 5
  • Data Object Preparation: 0.3s
  • Enable Alternative Advertising Mode: true
  • Force DFU: true
  • Enable Experimental Buttonless DFU: false

In my Flutter app I have the following function that tries to replicate mostly the above parameters:

Future<void> startDFU() async
  {
    await NordicDfu().startDfu(
      widget.deviceID,
      'assets/20230727.zip',
      numberOfPackets: 5, //I assume this is same as PNR(s)
      forceDfu: true, 
      onProgressChanged: (
          deviceAddress,
          percent,
          speed,
          avgSpeed,
          currentPart,
          partsTotal,
          ) {
        print('deviceAddress: $deviceAddress, percent: $percent');
      },
    fileInAsset: true,
        onDfuCompleted: handleDfuCompleted,
        onDfuAborted: handleDfuAborted,
        onDfuProcessStarted: (String deviceAddress) =>
            print("DFU PROCESS STARTED"),
        onDeviceConnected: (String deviceAddress) =>
            print("DEVICE CONNECTED"),
        onDeviceConnecting: (String deviceAddress) =>
            print("DEVICE CONNECTING"),
        onDeviceDisconnected: (String deviceAddress) =>
            print("DEVICE DISCONNECTED"),
        onDeviceDisconnecting: handleDeviceDisconnecting,
        onDfuProcessStarting: (String deviceAddress) =>
            print("DFU PROCESS STARTING"),
        onEnablingDfuMode: (String deviceAddress) =>
            print("ENABLING DFU MODE"),
        onFirmwareValidating: (String deviceAddress) =>
            print("FIRMWARE VALIDATING"),
        onError: handleError,);
  }

From the logs, everything looks fine until when DFU actually starts to upload and then it throws exception at 0%.

Hi @samnbd are you able to do it on Android? I haven't tested it on Android though.
