 +===== Firmware =====

 +The original watch firmware runs on S132 SoftDevice ver 2.0.1. \\ 
 +The device contains an OTA bootloader that can be used with the generic Nordic upload tool, so new firmwares can be uploaded safely. \\ 
 +Just make sure you have a way to reset the device if you screw up.
