Secured update mechanism
The new software is copied into the flash Module’s memory but the previous software is not
affected by this copy. During this process, if an error occurs before the end of file transfer
(Bluetooth disconnection, data transfer stopped,…), the module will restart with the previous
software version.
The checksum of the new software is included into this new software. If the new file is
correctly written into the flash, when Module will reboots, the new checksum internally
calculated is compared the checksum of this new software. If checksum are equals, the new
file will overwrite the previous one. During this process, if power supply is turned off, the
remaining data will be continuing to be written where it has been stopped at the next boot.
