Product Highlights

BTM-100 Series Bluetooth Low Energy (BLE) modules are designed for simple integration with high-value assets and offer seamless proximity services across iOS, Android, and other emerging mobile environments. All models of the product family can be customized to meet the needs of most monitoring and data collection applications.

The self-contained BTM-100-B is designed to be easily installed at the time the asset is manufactured or later after fielding. It is battery powered providing four years of operation and remains active (continuously broadcasting) from the moment batteries are inserted or replaced.

Key Features

The BTM-100-B features a Watch-Dog-Timer (WDT), an electronic timer that detects and recovers from firmware malfunc-tions. During normal operations the firmware resets the WDT at predetermined intervals to prevent from lapsing or timing-out. If there is a program error from which the firmware fails to reset the WDT times-out and generates a hard-reset rebooting the module, ensuring always-on operation. The BTM-100-B electronics are encased in Dow Corning® 1-2577 conformal coating for enhanced environmental performance.
