I wasn't aware of that. That should do the trick. If you get into trouble, can you create a new question? This is drifting a bit from the original question.

Unfortunatelly also the battery is built-in and fixed. I saw question C and seems to work, on the other side, is it enough to call restart_in_bootloader() like the OTA Tester application does? In that case i can send a payload with custom commands that can trigger that function and restart the device in bootloader mode. Thanks Max

You mean that your final product does not have buttons? Then you need buttonless DFU.

One method is described in question C here.

Does the user have access to the battery on the final product? Then you could maybe have the bootloader running for a certain time every time the battery is inserted, then jump to the application. You can do this by checking the NRF_POWER->RESETREAS register (sd_power_reset_reason_get()). On battery insert all flags should be 0. On a soft reset the SREQ flag should be set.

With ANTware II i can start the bootloader, can't understand why the OTA updater 1.4 can't...

I only got a problem right now, do i need to to press button1 and reset to enter bootloader or there's another way? After uploaded the ota tester application i can't run the bootloader without the buttons combination... my final product will be not accessible for that. Thanks

I'm sorry,

I did not configured well the target firmware code, now it works.

Thanks Max

What application are you uploading? I'm assuming you have tested it on the board without the bootloader?
