RE: nrf52840 DFU flash problem

Hello,

The bootloader in SDK14.X.X is not production quality, and I really don't recommend you to use this version. This is not something you can fix. The issue is in the softdevice, which is also not a production quality softdevice in SDK14.X.X. SDK15.0.0 is the first SDK that has a production quality softdevice for nRF52840.

S332 is not quantifiable with the nRF52840. It is intended for the nRF52832.

The good news is that the ANT softdevice for nRF52840 is under development. We expect the alpha version to be released in about 1 month, and the production release to be released in about 2 months.

So if it is possible, I would hold on on the bootloader part of your project until this is ready.

The reason why there isn't a S332 or S340(I would assume the name will be) in SDK15.X.X is that we don't have any ANT softdevices based on S132 or S140 yet.

Best regards,

Edvin
