I try to connect Core Body Temperature sensor with Edge 1040 according to instructions provided by Core and Garmin. Edge 1040 display shows "Wake up sensor to connect.", but the sensor in active. I have installed the latest firmware version to both Core sensor and Edge 1040. I had no problems pairing the Core sensor with Fenix 6X Pro Solar and Edge 830. I have pretty much the same Connect IQ data fields installed in all devices. Any suggestions what to try next?
