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. ### 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。 ### 5/5 — im cuming *2024-07-22* 🥵🥵🥵🥵😮‍💨😮‍💨😮‍💨🤭🤭🤭 ### 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. ### 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 ### 1/5 — 毁我青春 *2018-11-08* 垃圾软件 ### 4/5 — Download is very slow... *2018-08-21* Dont know why... ### 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 ## Frequently asked questions about nRF Toolbox ### What devices does nRF Toolbox support? nRF Toolbox is compatible with iPhone and iPad devices.
