Patent ID: 8244892

Claim:
Radiocommunication device comprising: at least one memory containing a starter software module and a use software module, at least one electronic processing unit linked to the memory, at least one radio circuit controlled by the processing unit, wherein the starter module is being configured to run automatically in the processing unit during the operation of the radiocommunication device, wherein the use module is being configured, when it is run by the processing unit, enable radio communication between the radiocommunication device and a radiocommunication network according to a Bluetooth protocol; wherein the starter module is configured to: setting up a simplified radio link of the radiocommunication device with the radiocommunication network; carrying out a download operation by the said simplified radio link, an update of the use module; and storing said update in the memory of the radiocommunication device; wherein the following layers of the Bluetooth protocol are implemented to allow the radio communication of said simplified radio link: a “LC” layer (real time control of the radio link): the “LC” layer is limited to the simple multiplexing of data to create connections, a “LM” layer (real time control of the radio link): the “LM” layer is limited to a negotiation restricted to the incoming connections, without audio, without authentication or encryption, a “L2CAP” layer: the “L2CAP” layer is to control, signalling and multiplexing limited to a single service, a service layer: the service layer is configured to downloading service; and wherein the starter module is configured to communicate with the radio circuit controlled by the processing unit to perform a normal operation mode and downloading mode, wherein the normal operation mode driving the execution of the use module, wherein the downloading mode enabling the download of an update of the use software module and not driving the immediate execution of use software module, the said starter module being adapted to receive an instruction to switch normal operation mode by the said simplified radio link.
