Possible reasons:
1. During the mapping process, the distance between the phone and the robot is too far.
2. Large or high obstacles with significant gaps are present during the mapping process.
We suggest trying:
1. Ensure that during the mapping process, the distance between the phone and the robot does not exceed 6 meters.
2. While mapping, avoid situations where either the phone or the robot is too close to large obstacles such as big trees, tall walls, or buildings, as this can cause Bluetooth disconnection.
