The present disclosure provides a near field communications (NFC) detector network for use in an implantable medical device. The NFC detector network includes a combined Bluetooth low energy (BLE)NFC antenna, a BLE transceiver, a BLE path electrically connecting the combined BLE/NFC antenna to the BLE transceiver and configured to communicate BLE signals received at the combined BLE/NFC antenna to the BLE transceiver, and an NFC path electrically connecting the combined BLE/NFC antenna to the BLE transceiver, the NFC path configured to generate an activation signal for the BLE transceiver based on an NFC signal received at the combined BLE/NFC antenna.
