Why not message 'Update finish' ?

if the update was success the module will be reboot to the new firmware.
I plan to add a option to allow to change this behavior.

[Opticcenter]

How to receive messages about the status of the update?
Update OK
Not Update
Update Failed
?

[Links2004]

its only reboots when the update is ok,
if there is no update or it failed you will get the return value.

@Links2004 Little bit off topic. But can you take a look at this issue please? #1156 I've been waiting for response for 7 days already. Thank you

[marvinroger]

@Links2004 yeah, adding an option to not reboot automatically would be great, I need to run some code (EEPROM-related) before rebooting. Furthermore, it is easy to do, as the handleUpdate already have a reboot parameter.

[Links2004]

yes the handleUpdate reboot change where the preparation for this ;)

[marvinroger]

But where to put the parameter? The update function is already quite-heavy in terms of parameters. After https?

[Links2004]

i need add it on the end or it will break all existing code.
and yes it will be the ~7 parameter.

[marvinroger]

Great! We will need to update the docs / examples too. Thanks btw ;)

I added a pull request #1817 to add a callback when an update actually starts, i.e. after it was verified that a new file exists and the server says to update the code and just before downloading begins. All other stages except for the pre-reboot can be done easily by printing before and after the function call and during the update all tcp and udp connections besides the one for the update are suspended anyway so progress in the middle cannot be sent.

If restart is not done automatically you can then also send a notification after the function completed and you go on to restart yourself.
