[gnrboy]

Hi i have problem i can flash  via st-link but when i want program nrf52832 via bluetooth(smartphone). i create zip with bootloader, softdevice and app and that zip send to smarphone. i connect smarphone and nrf52832 and start dfu and choose that zip but then nrf52832 change its bluetooth name and breaks connection.

I have found where is error. Im using older version of android app  nRF connect. On new version when you want to update its not showing graph of update .zip on  chip after first flashing. Tested on nrf toolbox android app and it works.
