The wireless update feature allows to perform a firmware update of the eZ430-Chronos wrist module wirelessly, that is the Chronos module does not need to be opened. The wireless update software should be seen as an application and not as an universal BSL. It can only be invoked by the main application, which needs to be created in a certain way (see Section 3.6.3.2). In addition it may must be modified to comply local RF regulatory. The current consumption during the update process may be significant. Considering the small battery capacity, the update software is intended to be used only occasionally.
NOTE
References in the software projects and the menu items of the Chronos module refer to it as "RF BSL" and "WBSL" for simplicity reasons.
Whenever the wireless update is activated on the Chronos module, it returns to the main application with a reset, wether or not an update was performed. Time, data, alarm, and other RAM-based data are lost.
