Could you try to disable the WDT in your application and see if that resoves the issue?

NO, no mesh is created. the other devices are all advertising.

I have a watchdog in my program, is it possible that the watchdog causes the error.

This could further suggest that this is a congestion problem, but if the other devices are only advertising and not in a connection, then I do not think this is the case. Are you creating some kind of mesh?

Yes, it looks like that.

Do you see the errors happening more often when there are many devices?

RE: nrf51822 dfu error

The devices are close to the phone, distance is less than 1m. Sometimes there are many peripherals(10~20), sometimes there are only one. I'm developing on my own custom device, including nRF51822(QFAC) and MPU9250.

To me it could sound like this is a bad link, i.e. either there is a lot of interference or the device is far away from the central. Are you developing on a custom device or one of our development kits?

There is another problem. when I update the device, two errors occur many times. (about 20~40%)

The connection has timed out unexpectedly.(code:6)
(code: 10)

It looks the same as normal when the error occurs.

Oh, sorry! I forgot that the log feature is only available in nRF Connect. Are there any common symtoms when the error occurs?

RE: nrf51822 dfu error

how could I get the log? with Xcode? The error occurs randomly and rarely. It's hard to get the error log.

I am unfamiliar with the Nordic mBed library and how they use our bootloader so I am not quite sure what the cause of the issue is. Could you post the log from the nRF Toolbox app when the update fails?

RE: nrf51822 dfu error

Darren16 — Sat, 22 Oct 2016 06:33:15 GMT

The error still occurs after I updated the app. Do you have any other idea?

Happy to help :)

RE: nrf51822 dfu error

Darren16 — Wed, 12 Oct 2016 09:27:39 GMT

Thank you. I have updated to the latest version, and will test it.

RE: nrf51822 dfu error

bjorn-spockeli — Wed, 12 Oct 2016 09:12:33 GMT

Ok, my advice is still that you should update to the latest version of nRF Toolbox.

RE: nrf51822 dfu error

Darren16 — Wed, 12 Oct 2016 08:16:54 GMT

I use the mbed library. nRF51822: developer.mbed.org/.../ BLE_API: developer.mbed.org/.../

RE: nrf51822 dfu error

@darren16: Do you mean that use our SDK bootloader or do you use a Nordic MBed library( ifso could you provide a link to it)?

RE: nrf51822 dfu error

Darren16 — Wed, 12 Oct 2016 00:56:00 GMT

I develop programs on ARMmbed. And use Nordic Semiconductor's nRF51822 Library(latest version).

The newest version is v4.1.0, see this page in the App Store I suggest that you upgrade to the latest version and see it that resolves the issue. Again, which SDK and SD version are you using?

RE: nrf51822 dfu error

Darren16 — Mon, 10 Oct 2016 12:46:30 GMT

I use iOS app. The nRF Toolbox app is of Version 2.5.

RE: nrf51822 dfu error

bjorn-spockeli — Wed, 05 Oct 2016 14:55:23 GMT

Which SDK and SD version are you using? Are you using the Android or iOS app to perform the update? Which version is it? If you're using Android, do you see the same behaviour with the nRF Connect app?
