The problem seems to be an out-of-spec 32.768kHz clock on the modules we are using. If I synthesize the clock from the 32MHz clock then everything works fine.

You can close this ticket.

Thanks.

Thanks.

I'll forward this to our developers and ask if they have seen anything similar. I haven't seen any issues with this before.

The nRF Connect app shows the segment number that it's transferring. With the PA/LNA enabled I can see it count individually, i.e. 1/35, 2/35, 3/35 one at a time. Without the PA/LNA it jumps thought them much faster, i.e. 1/35, 4/35, 8/35 etc. So it's at least three times faster without the PA/LNA.

Hi.

Could you elaborate on "DFU upload is now much slower"? How much slower is the transfer after PA/LNA?

I'll create a ticket for our Mesh developers, and ask if they have seen any problems with this before.
