This disclosure provides various ways to enable a BLUETOOTH Low Energy (BLE) communication capability for a field instrument. An apparatus is configured to perform a method for providing BLE communication capability to a legacy field instrument in an industrial control system. The method includes receiving, by a BLE adapter coupled to the field instrument, information from the field instrument according to a protocol that is native to the field instrument. The method includes converting, by the BLE adapter, the information into a BLE communication protocol. The method includes transmitting, by the BLE adapter, the converted information to an external device over a BLE communication link.
