Edit the Nymi Bluetooth Endpoint Configuration File

The Nymi Bluetooth Endpoint application enables BLE functionality for Nymi Lock Control and BLE tap. Editing the Nymi Bluetooth Endpoint configuration file adjusts the behavior of these features.

Nymi Lock Control and BLE tap behavior is dependent on the distance between the Nymi Band and the BLE radio antenna. The distance between the radio antenna and the Nymi Band is represented by changes in the Received Signal Strength Indication (RSSI) value, and is determined by measuring the radio signals received by the BLE radio antenna. Close distances between the Nymi Band and BLE radio antenna result in stronger signals, and far distances result in weak signals. BLE tap and Nymi Lock Control actions occur when the trends in changing RSSI values reach a certain threshold defined in the Nymi Bluetooth Endpoint configuration settings.

The default RSSI values used by Nymi Bluetooth Endpoint may not be optimal for certain users. For example, under default settings the user terminal may unlock when the user is too far away, or the user terminal may accidentally lock while the user is present. In these cases, the BLE radio antenna is too sensitive, not sensitive enough, or the placement of the BLE adapter prevents the Nymi Band from being read consistently. Edit the Nymi Bluetooth Endpoint configuration settings on a user terminal to adjust for these discrepancies.

To adjust the sensitivity of BLE taps and Nymi Lock Control, edit the Received Signal Strength Indication (RSSI) values in the Nymi Bluetooth Endpoint configuration file, nbe.toml.
