I am investigating the use of Mender as an update mechanism for a handheld device, in fact a couple of devices but one step at a time.
The devices are not permanently connected to any network. In fact they are more, rarely connected to a network. I want however to be able to apply updates to the application running on the handset but only on demand. So the user would take the device to somewhere where an update server wifi AP is available, turn on WiFi on the device, configured to only be able to connect to a pre configured AP, and connect. the server then identifies the device, performs all the checks and passes an update to the client. the update is applied and the device then shuts down the WiFi hardware to conserve power.
Could Mender be configured to perform in this manner?
Is the rollback feature able to be disabled or is it necessary to do so?
I am running a CC6 UL / Yocto based project
