A method of updating an infusion device, the method comprising: uploading measurement data from the infusion device to a remote device, the measurement data comprising one or more measured values correlative to a condition of a user associated with the infusion device; determining, by the remote device based at least in part on the measurement data, control information utilized by a control scheme or algorithm implemented by the infusion device; autonomously initiating establishment of a temporary wireless point to point communication session with the infusion device over a network, wherein autonomously initiating the temporary wireless point to point communication session further comprises autonomously initiating, by the remote device, a first communication session over a second network with an intermediate device previously paired with the infusion device based on an association between the infusion device and an intermediate device established by the remote device, the intermediate device automatically establishing the temporary wireless point to point communication session with the infusion device over the first network in response to the remote device initiating the first communication session; in response to the intermediate device establishing the temporary communication session, automatically transmitting, by the remote device, the control information to the intermediate device via the first communication session over the second network, the intermediate device retransmitting the control information to the infusion device via the temporary wireless point to point communication session over the first network; and automatically terminating the temporary wireless point to point communication session after the control information has been transmitted to the infusion device. uploading measurement data from the infusion device to a remote device, the measurement data comprising one or more measured values correlative to a condition of a user associated with the infusion device; determining, by the remote device based at least in part on the measurement data, control information utilized by a control scheme or algorithm implemented by the infusion device; autonomously initiating establishment of a temporary wireless point to point communication session with the infusion device over a network, wherein autonomously initiating the temporary wireless point to point communication session further comprises autonomously initiating, by the remote device, a first communication session over a second network with an intermediate device previously paired with the infusion device based on an association between the infusion device and an intermediate device established by the remote device, the intermediate device automatically establishing the temporary wireless point to point communication session with the infusion device over the first network in response to the remote device initiating the first communication session; in response to the intermediate device establishing the temporary communication session, automatically transmitting, by the remote device, the control information to the intermediate device via the first communication session over the second network, the intermediate device retransmitting the control information to the infusion device via the temporary wireless point to point communication session over the first network; and automatically terminating the temporary wireless point to point communication session after the control information has been transmitted to the infusion device.
