Firmware upgrade is available in the LunaR and this will be done ’Over the air’. This is done by sending technical data through bluetooth.


Once firmware upgrade failed the App will retry to resume firmware upgrade within 2 minutes.LunaR will also be broadcast for 2 minutes to hope to still get the data where it got left off.


The firmware upgrade should not lose the pairing information and the watch should reconnect with the phone without any problems.
