Blue 2-1 firmware won't update from 2.15 to 2.18

That might be a quirk of zigbee2mqtt storing the old version in cache, take a look at this post.

Blue Series 2-1 Firmware Changelog | VZM31-SN

For those of you who did the update in Z2M but are still seeing the “old” firmware, it appears to be a Z2M bug (maybe related to this, or this issue). Z2M keeps a cache of the firmware and doesn’t seem to always update it after the firmware update applies. If you want to verify what firmware your device has, go over to the dev console for the device and send a genBasic message with the swBuildId attribute and you’ll see the real firmware version.
