DFU with SoftDevice s120

[Gabriel C.]

Hello everyone,

I had some troubles some time ago with Softdevice s120, and finally solved it to work with nRF51822 thanks to Aryan.

The problem is that, when I upload a zip file, which I generated with the tool from THIS post the app does not start.

Seems that the the SoftDevice and Bootloader are not affected by the upload, because if I load the app again with Keil it starts properly.

Also, after the upload, the device is not in DFU mode anymore(cannot find it through BLE scan).

I am not able (or I don't know how) to check if the app was written in the right place...

As the Bootloader was meant to work with s110, could be something related with the memory map? I tried to see where to modify this values in order to set the address where to write the app, but I'm not able to find it.

Thanks in advance for your help,

Best regards, Gabriel C.
