Ok. Good to know that it only doesn't work on Android. It means that it is set up correctly, at least. Perhaps the log reveals something.

If the log doesn't say anything useful, we may need a sniffer trace as well. In that case you may need an extra DK either way. (or an nRF52 Dongle can be used, but note that this is mostly only usable for tools like this, since it doesn't have a debugger. If you want to develop on two devices, I recommend two DKs).

For me it's work with IOS but not with an Android Phone.

I try tomorrow to see the log when I upload the FW.

I don't have another DK to test with nRF Connect fo Desktop.

I don't have an Android phone, but I am able to upate the application using nRF Connect for desktop, nRF Connect for iOS and nrfutil.

What does the log say when you try to upload the FW using nRF Connect for Android? And have you tried using nRF Connect for Desktop or nrfutil? (requires another DK).

I have the same log than you.

You arrive to connect your Android Phone with nRF Connect on the nRF ?

Sorry. We don't have any tutorials for exactly this.

I don't have an nRF51 DK to test on, but looking at the nRF52 pca10040_debug example from the same SDK version, and programming only the softdevice and the bootloader gives this log:

What application are you using to monitor the log? NB: The log is an RTT Log, and not a UART log. Try using J-Link RTT Viewer.

Yes I'm using the nRF51DK. I use the SDK 12.1 and I use the bootloader_secure, the example in dfu folder.

For the test I'm using the pca10028_debug example but it's didn't work and I don't know why RTT log works. Can you give me a tutorial ?

Hello,

I don't know exactly what is happening.

Are you using the nRF51? What SDK version and bootloader are you using? Depending on the SDK version you are using, can you see a pca10028_debug example folder right by the example you are currently using? If so, can you please try to run that bootloader instead, and then try to monitor the RTT log to see what it says?

Best regards,

Edvin
