Hi,
MCU: nrf52840
SDK: nRF5_SDK_17.1.0_ddde560
I am facing such an issue, sometimes after the device's OTA success, and then I would like to upgrade to another version, the nRF connect app always returns a DFU Error(0x01), which is shown in the below image. if I delete the bonding on both the device side and the Smartphone side and re-bond again, it can be fixed.
What is the root cause?
