SDK6 DFU and 32KHz Crystal relationship

[Nguyen Hoan Hoang]

Hi, I got the DFU modify to use Synthesize clock (NRF_CLOCK_LFCLKSRC_SYNTH_250_PPM) working with SD7 and SDK6. Tested on a board with the 32 KHz crystal, everything works fine. Tested on board without the crystal it got stuck at DFU discovery phase on iOS. See attached screen shot. Can anyone explain the problem please. Thanks.

Yes, it does advertise. The iOS app can see I. After I select it, the App goes into the upload screen and you can see there the name DfuTarg and it got stuck in Discovering. The Upload button stayed grey. See the picture I attached. Same problem with both SYNTH Clock and RC Clock

Hi,

Unfortunately, softdevice 7 is not supported by the current version of the iOS application. We're working on updating this.

Best regards Håkon
