Nordic Semiconductor has released SDK 14, which supports Bluetooth 5 -compatible softdevice.
We’re thinking about if we should upgrade the examples to SDK 14. On the positive side, this would bring us BLE-5 compatibility and access to newest development from Nordic Semi.
On the negative side, example firmware, especially Espruino, would no longer be compatible. We’d of course port the Ruuvi Firmware and Nordic has already provided Eddystone.
Upgrade path from 12.3 to 14.0 is reliable, but there are reports about downgrade corrupting bootloaders.
Give us your thoughts on this matter. Is the possible confusion about versioning firmware to suit the tags worth the hottest new feature?
