Hi,
Using SDK12.1 with nrf52. Have SD and bootloader on the device and trying to load application via BLE DFU. It randomly gets stuck. (see attached screenshot)
And if I do it via nRF Connect App i get "[DFU] Invalid response received (response: 0x600408, expected: 0x6004..) ". Below is the full log:
