Hii,
We are using currently nRF SDK12 and nrfutil for performing DFU over ble. we are able to do it by pressing button on nrf51822 Dk kit at time of restart and putting it in to Bootloader mode.
Now we trying to implement out buttonless DFU. I am using example given in nRF sdk12 (experimental buttonless DFU) and nrfutil for performing OTA with ble. but when i try to perform DFU i get following error.(CCCD not found please find attached screenshot of the error)
Hello,
It seems like it can't find the cccd handle for the Secure DFU Control point.
Have you changed anything in the bootloader?
Can you please try to connect to the DFU targ with nRF Connect for Desktop, and see what Services it has? Does it look like the screenshot below?
Can you please attach a screenshot of this window with your DfuTarg?
Best regards,
Edvin
