Target: Nordic NRF52840
Mbed OS: Version 5.13
Related PR: [#10709]
I would like to perform BLE OTA direct firmware upgrades (DFU) using the nRF52840. Until now this was doable via the Nordic S140 softdevice, for example by following this guide. #10709 changed the default Bluetooth stack to Cordio. Does that mean, that the S140 can no longer be used with the current version and DFUs are not possible any longer?
So far, I found [#3363], [#4587] and [#5412], but all of them are closed or inactive. I also found this mbed forum thread from 4 months ago, that said that this feature is high priority and still in planing. But nothing newer than that.
