FWIW this bracelet I got https://www.gearbest.com/smart-watches/pp_009557274002.html is reported by nRF Connect as made by Nordic Semiconductor so it may be good hacking target? Looks like it is this one http://www.globalsources.com/gsol/I/Smart-bracelet/p/sm/1160255861.htm
Otherwise it is usable bracelet with average/poor fitness app DroiHealth but everything works and battery life is good. I charged it when I got it last week on Wednesday and it still reports %62 of battery today after wearing it almost every day/night. The app has firmware update option over bluetooth but sadly it is up to date so currently there is no firmware update available.
