### 1/5 — 全く使い物にならない

*2024-11-18*

接続しようとしている端末とは違う端末(もちろん自分で所有している物)をリストに表示しているし、パッチを当てたい端末が検出されないのだから勿論ファームウエアのアップデートなんかできない。これは何？ひょっとして個人の端末から何かデータを抜きたいのか？
本当に不愉快。イライラする。

### 1/5 — dfu文件打不开

*2021-05-08*

啊这

### 1/5 — .hex files can’t use for DFU

*2020-05-26*

I can’t use . hex files any more for DFU.
It was possible with previous versions.
Any specifications changed?

**Developer response:** Support for hex files is still there in the underlying DFU library. However, in the new version of the app we decided to focus on improving the UI and some legacy features may have been put on hold. You may use nrf util (https://github.com/NordicSemiconductor/pc-nrfutil) to create zip file. If the device you're using is not based on a very old SDK (before 7), this should work. For legacy DFU use branch 0.5.x.

### 1/5 — 毁我青春

*2018-11-08*

垃圾软件

### 1/5 — 很垃圾

*2018-03-16*

搜索蓝牙容易搜索不到，而且搜索出来的蓝牙没有根据信号强度排序，很多蓝牙信号时，找设备非常麻烦，要人命的是，连上蓝牙，硬件都没有显示连接的蓝牙图标（用手机系统连都有图标，自己做的app连接也有图标），经常升级错手环，真是烦死，垃圾

### 1/5 — 升不了级

*2017-02-09*

升不了级

### 1/5 — dfu阿啊阿啊

*2016-09-23*

能不能搞好了？不能用啊dfu不能用啊，文件都拷贝不进去，还闪退。

### 1/5 — 新版本的DFU功能用不了。

*2016-09-20*

新版本的DFU功能用不了。

*2016-09-16*

### 1/5 — Crashes on startup

*2016-04-22*

The app doesn't start. Crashes as soon as the loading screen comes up. On iPhone 5

🥵🥵🥵🥵😮‍💨😮‍💨😮‍💨🤭🤭🤭

### 5/5 — Fantastic

*2016-04-23*

Wonderful app to test firmware updates without the need to recode our beta app

### 5/5 — Super Useful Util

*2016-02-12*

Thank you Nordic engineers for maintaining this. Unfortunately iOS 9.2 has broken long press on zip file attachments in email. Verified by two of my associates. Maybe its time to associate DFU payloads with a .zippy extension to work around the genuises at Apple.

### 4/5 — Download is very slow...

*2018-08-21*

Dont know why...

### 3/5 — Not able to delete user zip

*2020-05-15*

I am no more able to delete the zip packaged. It is hard to manage duplicate zip files in absence of this functionality

### 3/5 — Last release is not working with uart in Nrf51 dk.

*2016-02-17*

It used to work with the previous version.

### 3/5 — One problem

*2015-10-26*

It's a nice tool however only one problem, when I use HRM to detect the heart rate it only shows the first one digit especially when the heart rate is more than 100, say 126, it only shows 1... on screen

### 2/5 — V6.0 won’t reconnect

*2025-12-14*

Jarring update hides presets and refuses to reconnect to NUS Nordic Uart Service  if device disconnects requiring app restart. Please fix the reconnect bug. Even manually reselecting device leaves stuck stale state. Way more clicks required to get to loaded presets, not shown by default when configured, hidden under all messages. I do like rapid switching between presets. Maybe needs a presets keyboard to better use screen space and allow more presets. Please fix reconnect as i cant roll back this auto update.
