7 years ago Hi, the "Characteristic write error: 3" you get is "Write Not Permitted", so it has to be some caching issue.
Could you, please, in your DfuService class override isDebug() method and make it return true or: BuildConfig.DEBUG?
@Override
protected boolean isDebug() {
return BuildConfig.DEBUG;
}You will get more logs there. Then paste the new logcat output here. I'm mostly concern about a text: Refreshing result: true/false or En exception occurred while refreshing device that is generated by this method.
Other questions:
- I've heard you use Legacy DFU from SDK 9, is that true?
- What devices you get this issue on?
- Do your devices use buttonless jump?
- Do they change address when in bootloader mode or not (in SDK 9 they by default don't)?
- Do you use bonding? Do you want to keep bonding after the update is complete?
Thanks!

Hi,
My application is a little bit different with others. We do two DFU process at the same time since our big app size. Normally our first DFU process would succeed. But the second one would fail. This issue would only be present in some special Android phones. Most Android phones work. But even for the same failed Android phone, it would succeed sometimes. The following log was reported by Android system. Please advise.
by the way we are using SDK9 with S110 softdevice. And single bank is used for bootloader.
