A medical monitoring and communication system for wireless communication between an implantable medical device, a mobile user device, and a remote server includes a sensor device coupled to the implantable medical device. The sensor device is configured to default to a master mode prior to pairing with the mobile user device, listen for a request to connect from the mobile user device, refrain from communicating with the mobile user device responsive to the request to connect from the mobile user device being invalid, and switch to a slave mode to allow cooperative pairing with the mobile user device responsive to the request to connect from the mobile user device being valid. The mobile user device facilitates communication between the sensor device and the remote server when the mobile user device and the sensor device are cooperatively paired.
