Dear all,
As some of you have pointed out, if we want to perform DFU and having a watchdog running, the boot loader should embed a watchdog feed. I have successfully managed to do so. And DFU performs OK until the app reboots. Then, I loose my app and the NRF restarts in my boot loader mode. If I remove the watchdog everything works perfectly.
Did anyone had that issue and may give some ideas to process completely the DFU. The only way I can retrieve my app is to flash completely my NRF. Thanks for your answers,
Cheers,
D.
