1. An implantable medical device (IMD), comprising:
a transceiver configured to communicate wirelessly, with an external device (ED), utilizing a protocol that utilizes multiple physical layers;
the transceiver configured to transmit information indicating that the transceiver is configured with first and second physical layers (PHYs) for wireless communication;
memory configured to store program instructions;
one or more processors configured to execute instructions to:
obtain an instruction designating one of the first and second PHY to be utilized for at least one of transmission or reception, during a communication session, with the external device, wherein the first PHY is the one designated based on connection criteria for a communications link, wherein the connection criteria include at least one of a data throughput requirement, a communication type, a size of data set to be transferred, a battery indicator, a telemetry break condition or link condition of the communications link between the IMD and ED;
manage the transceiver to utilize, during the communications link, the first as designated; and
change to the second PHY, while maintaining the communications link, based on a change in the connection criteria.
