1. A communication system for a wireless message transfer between an implantable medical device (IMD) and an external device, wherein the IMD is configured to monitor a health status of a patient and/or configured to deliver a therapy signal to the patient, wherein the IMD comprises a processor and a transceiver module configured to bi-directionally exchange messages with the external device via a single threaded command architecture, wherein the processor is configured to switch between a predefined active state and a predefined processing state, wherein the external device is configured to produce and send request messages to a transceiver module of the IMD, wherein each request message comprises a sequence field at a predefined location within the request message which is toggled between at least a first value and a second value associated to the sequence field, wherein the request messages comprise a first request message and a second request message, wherein when the external device receives a valid response from the IMD to an immediately previously sent first request message, the second request message contains the second value, and wherein when the external device does not receive a valid response from the IMD to an immediately previously sent first request message, the second request message contains the first value.
