Hello, as mentioned in subject, I have done DFU on nrf51 DK. it is tottaly working fine. As soon as I try to work with Nrf51822 QFAC custom board. It goes in to bootloader mode once bootloader is laoded thorugh NRF go studio. Also while transferring zip file through app it gets successfully uploaded . but it does not comes out from DFU mode. it continues to advertise as DFU trag only. Same procedure works very fine with NRF51DK. Please suggest me what can be the issue?

Hi,

I don't see any reason why the DFU process will not go through when using your custom board. What you could do is to take a hex dump after the DFU and then compare with the same hex dump you tested on to the DK to see if there are any differences?

Best regards,
