pilloxa / react-native-nordic-dfu Goto Github PK

Hello,

I am investigating the viability of this library. The question is: how to obtain the MAC address on an iOS device?

Best Regards

For dfu to show device i need to run
sd_ble_gatts_service_changed() to the BLE_GAP_EVT_CONNECTED case in ble_evt_handler() in main.c.

Do you have any example for it as on my device it is getting cached and failing the dfu process

Hi everyone,
After success update firmware something happens with react-native-ble-manager. I can't scan perf, can't connect\disconnect devices. Only restart application help me.

Some additionally:
I try debug IOS part of library,
as for me problem inside iOSDFULibrary.framework, because I remove step by step some code part from wrapper and can't doing anything with this problem

DFU working fine in android v6 but giving error in android v9 in release mode (working fine in debug mode in android v9). screenshot attached below.

Version info:-
react native - 0.59.10
react-native-nordic-dfu - 1.1.2
windows 10 64 bit

Hello. Had to do lots of upgrades recently, the Swift 4.1 issue (
#24 ) being one of them, and at least that eventually worked...somehow. Still, one different problem remains:

Among the iPhones I'm working with, one is on iOS 12 beta, which requires Xcode 10 beta for developing. After following all the manual installation instructions, Carthage updating and whatnot, my project builds, but then running it causes the following error to occur on startup:

dyld: Symbol not found: __T0BoWV
Referenced from: /private/var/containers/Bundle/Application/E5D7F3EC-6EEA-4A07-87E2-FAA7FD91AD94/placeholder.app/Frameworks/Zip.framework/Zip
Expected in: /private/var/containers/Bundle/Application/E5D7F3EC-6EEA-4A07-87E2-FAA7FD91AD94/placeholder.app/Frameworks/libswiftCore.dylib
in /private/var/containers/Bundle/Application/E5D7F3EC-6EEA-4A07-87E2-FAA7FD91AD94/placeholder.app/Frameworks/Zip.framework/Zip

Building the app via Xcode 9.4 and installing it via Testflight on the iOS 12 device works fine, but can only run it via Xcode on iOS 11 and lower. Any fixes soon, or could there be something additional I have to do myself?
Same thing happens when I try to run the app on a different device via Xcode 10.

react-native-nordic-dfu: swift-4.1
react-native: 0.56
react-native-ble-plx: 0.10
iOS: 9 to 12.0
Xcode: 10.0 beta 4

Thanks for the library. There is a little typo in the examples in the instruction. name: "Pilloxa Pillbox" should be deviceName: "Pilloxa Pillbox".

Steps to reproduce:

react-native init AwesomeProject
cd AwesomeProject
npm install --save react-native-nordic-dfu
cd ios
touch Podfile

My Podfile:

target 'AwesomeProject' do
 rn_path = '../node_modules/react-native'

 # See http://facebook.github.io/react-native/docs/integration-with-existing-apps.html#configuring-cocoapods-dependencies
 pod 'yoga', path: "#{rn_path}/ReactCommon/yoga/yoga.podspec"
 pod 'React', path: rn_path, subspecs: [
   'Core',
   'CxxBridge',
   'DevSupport',
   'RCTActionSheet',
   'RCTAnimation',
   'RCTGeolocation',
   'RCTImage',
   'RCTLinkingIOS',
   'RCTNetwork',
   'RCTSettings',
   'RCTText',
   'RCTVibration',
   'RCTWebSocket',
 ]

 pod 'react-native-nordic-dfu', :path => '../node_modules/react-native-nordic-dfu'

end

post_install do |installer|
 installer.pods_project.targets.each do |target|
   if target.name == "React"
     target.remove_from_project
   end
 end
end

Install pods:

pod install

I get an error:

[!] Unable to determine Swift version for the following pods:
 - `iOSDFULibrary` does not specify a Swift version and none of the targets (`AwesomeProject`) integrating it have the `SWIFT_VERSION` attribute set. Please contact the author or set the `SWIFT_VERSION` attribute in at least one of the targets that integrate this pod.

I've recently updated my app from react-native 0.57.5 to 0.59.10 and react-native-nordic-dfu from 2.0.1 to 3.0.1. Everything was working fine before the update but now the app crashes (just closes itself down) without errors or warnings when running NordicDFU.startDFU on Android.

Everything works perfectly on iOS (I did the CocoaPods update).

I've tried with both correct and incorrect (just some random strings) deviceAddress and filePath, but it crashes anyways in NordicDFU.startDFU.

I'm running:

react-native: 0.59.10
gradle: 5.4.1
react-native-nordic-dfu: 3.0.1

It crashes both in emulator and on physical device.

I ran in to this problem when I tried to release my app to Appstore.

Code signing "Zip.framework" failed.

I have followed and double checked the iOS linking guide, but can't get it to work.

When we are trying to fo Dfu of the device Below message is coming on console.

{"framesToPop":1,"code":"4097"}

Please suggest what can be the issue

Having an issue building with this library using the 3.0.0

Followed all instructions in the readme

yarn add react-native-nordic-dfu
react-native link react-native-nordic-dfu

Created my podfile with pod init, added the path to the nordic dfu library.

also did a pod install. Outputs the following error:

[!] Unable to determine Swift version for the following pods:

- `iOSDFULibrary` does not specify a Swift version and none of the targets (`<app_name_here>`) integrating it have the `SWIFT_VERSION` attribute set. Please contact the author or set the `SWIFT_VERSION` attribute in at least one of the targets that integrate this pod.

Build with Xcode version 10.2.

Xcode Complains about RNNordicDFU.h not found. So I added the react-native-nordic-dfu to my search path. Now it complains that iOSDFULibrary is not found.

The readme is clearly missing information on how to successfully build a project with this repo

This error comes in android - DFU is working fine but showing Upload failed notification.

Error shows up in example app when Start Dfu button is pressed. If anyone had a similar problem or knows what my error could be let me know! Thanks in advance.

JSON value '0' of type NSNumber cannot be converted to NSString

NordicSemiconductor/IOS-DFU-Library#154 (comment)

Hi,
I have a zip bundled in the apk under assets folder.
I want to start DFU with path to this file.
What is the file path that I need to pass to startDFU method?

Thanks,

In my react-native project i'm using 'react-native-nordic-dfu' npm module. I have done react-native link react-native-nordic-dfu as well as manual installation steps(4-10). But after running the app it crash and throws Thread 1: signal SIGABRT dyld`__abort_with_payload: exception. I am not able to find any solution for that. Please let me know if anyone has solution for this.

Thanks in advance.

I'm using this lib. And I want to stop DFU progress after I use
NordicDFU.startDFU
Looking for your help
Thanks

This error occured on ios with react-native-nordic-dfu 3.0.0

Hi,

I installed the package for android according to instructions.
When running "react-native run android" I get the following error:
"Could not find method google() for arguments [] on repository container".
I don't understand why...
My RN version is 0.50.3.
I compared gradle configuration to the example project and everything is the same.
Any clue why I receive this error?
Thanks,

On swift, I can set some properties in DFUServiceInitiator class, but on RN, I can not do any property setting. I hope you can add some bridges to do it.

Suggestion arose from this comment

Add more descriptive error message. Better error descriptions would make both:

1. This library easier to use without a need to decipher real error meanings
2. Less issues that could be posted on github that you (maintainers) will have to worry about

Actual result:

Error says —

Firmware not specified /var/mobile/Containers/Data/Application/9BA61605-2A61-4D85-8068-CCDECB1DE4EC/Documents/PluginStorage/com.chuangmi.newlock.ios/DFU/cm_app_dfu_package.zip

Expected result:

Below are suggestions which may be further improved

• In case of lack permissions to access the file

Firmware location not accessible /var/mobile/Containers/Data/Application/9BA61605-2A61-4D85-8068-CCDECB1DE4EC/Documents/PluginStorage/com.chuangmi.newlock.ios/DFU/cm_app_dfu_package.zip

• In case of file not available at location

Firmware file not found /var/mobile/Containers/Data/Application/9BA61605-2A61-4D85-8068-CCDECB1DE4EC/Documents/PluginStorage/com.chuangmi.newlock.ios/DFU/cm_app_dfu_package.zip

Not sure but maybe there are more possibilities that could have better error descriptions.

I'm new to iOS development, but have got everything working on Android. Would anybody be able to check out my code and help me get it up and running?

https://github.com/jason2li/dfutest

After linking the library and trying to build the iOS app, I get the following error:

ld: /Users/stinodes/projects/com.minze.minzeflow/ios/Zip.framework/Zip compiled with newer version of Swift language (4.0) than previous files (3.0) file  '/Users/stinodes/projects/com.minze.minzeflow/ios/Zip.framework/Zip' for architecture armv7

I am sadly not an experienced iOS developer. To me an easy fix seems to be to install a Swift 3.0 version of Zip, but I might be mistaken of course.
If you guys have a version that has Swift 3.0 frameworks, then that'd be great! If not, would an older version of Zip work well? (assuming that swapping out the swift 4.0 code even fixes it)

The second I call NordicDFU.startDFU It gives me this error:

This is my code:

NordicDFU.startDFU({
    deviceAddress: peripheralID,
    name: "My Device",
    filePath: firmwarePath
})
  .then(res => console.log("Transfer done:", res))
  .catch(error => console.log(error));

This is the path to the firmware:
/var/mobile/Containers/Data/Application/5869AB60-ADF7-4FBD-94BD-2C9C2A10D626/Documents/RNFetchBlob_tmp/RNFetchBlobTmp_6k32nkgwxwrx77j66ofrsk.zip

My guess is that it has to do something with permissions, but I am not sure if it's necessary.

p.s I get this error on iOS, haven't checked on Android yet.

@Looveh @vikeri thanks for this awesome library!!!

Hi,
when I use this library to update our device firmware only application layer part will be uploaded. but when I use NRF toolbox all parts (bootloader + application) will be uploaded>
with dfu progress listener I only see 1 part, is there any bug?
should I extract it to 2 parts for uploading?

I'm trying to load a DFU file from a .zip file bundled within the app. The file sits at [project]/android/app/src/main/assets/firmware/filename.zip. On iOS, I'm using react-native-fs to get the path to the resource, and it's working as expected, but on Android, I can't figure out what path it might accept. Here's how it's working right now on iOS:

    const { localName, id } = deviceToUpdate
    const rootPath = Platform.OS == "ios" ? RNFS.MainBundlePath : "firmware"
    const fileName = 'firmware.zip'
    const filePath = `${rootPath}/${fileName}`
    const dfuConfig = { deviceAddress: id, name: localName, filePath }

    NordicDFU.startDFU(dfuConfig)

I can't figure out what path might work, and the docs aren't get about how the DFU path is getting resolved. Any one have an idea of how I can fix this?

@vikeri @Looveh @dariuszseweryn @reekris

As soon as I call NordicDFU.startDFU I get Firmare not specified error...

Not sure what I am doing wrong here:

const FB = RNFetchBlob.config({
  fileCache: true,
  appendExt: "zip"
});

FB.fetch("GET", "http://192.168.15.52.xip.io:8081/debugger-ui/myFirmwareFile.zip")
      .then(res => {
        console.log("file saved to", res.path());
        this.setState({ imagefile: res.path() });
      })
      .catch(error => {
        console.log(`FB_FETCH_ERROR: ${error}`);
      });

NordicDFU.startDFU({
      deviceAddress: peripheral.id,
      name: peripheral.name,
      filePath: this.state.imagefile
    })
      .then(res => console.log("Transfer done:", res))
      .catch(error => console.log(`Transfer error: ${error}`));

The file gets saved to:
/var/mobile/Containers/Data/Application/DD17EDE3-4DA3-4A07-9173-AA2B9073F037/Documents/RNFetchBlob_tmp/RNFetchBlobTmp_mwgdau6fiwdxlopjjx9wr.zip

I've tried using the hex file as well, but no luck... Could you please explain what I am doing wrong here?

This happens on iOS

Thanks!

This error occured on ios with react-native-nordic-dfu 3.0.0

My project builds properly but when the app runs on the simulator or a phone I get this error message. If anyone could shed some light on what I might be doing wrong. I've tried all the common fixes, cleaning then running again, renewing certificates, and even using a different toolchain.

Thanks in advance.

I'm am trying to get this up and running, but once I install this plugin, I can no longer run the application. I get the following error:

node_modules\react-native-nordic-dfu\android\src\main\java\com\pilloxa\dfu\RNNordicDfuPackage.java:19: error: method does not override or implement a method from a supertype
    @Override

I am working in Windows 10 and testing on Android (IOS will be next).

Hi there,

Thanks for your excellent work on this project.

I noticed after reconfiguring a RN project to include React via CocoaPods instead of being manually added to the project, that RNNordicDFU could no longer find the requisite headers and would fail to compile.

ex:

React/RCTBridgeModule.h not found

I'm opening a simultaneous PR to add pods public headers to RNNordicDFU's Header Search Paths.

Fwiw btw I appreciate your use of Carthage, I prefer it too. Unfortunately the official "blessed" advice for integrating RN with an existing app revolves around the use of CocoaPods still. Ref

Cheers,
