I agree with you about the convinience to be able to see the fw version number available in each SBrick!
In the present case it is to know, because before fw upgrade:
- LED ID: normally off / Identify function: LED on
After upgrade:
- LED ID: normally on / Identify function: LED blinking
As stated here in the forum, at Android one can use Nordic Semiconductor nRF Master Control Panel to read the firmware version.
Ok, seems my iPhone 5s did stall the update...
Turned the power off to the brick, tried again, same issue. Update status stops at about 98% and stays there.
Moved to my iPhone 5, did the same thing, and the progressbar moved to 100%, and showed a 'success' message. Took about 3 minuts!
1: It seems like the SBrick app does not test if the BT connection is working as expected, when doing this.
2: It would be Very nice to be able to see the FW version on the brick, so you have a small idea if the brick got updated or not! ;-)
I didn't measure the time but I upgraded 3 of them about 1hour ago... :)
It took something about 1min each and you should follow the progress from a blue bar in the phone screen.
After the firmware is fully uploaded into SBrick, it reboots and flashes the firmware in the SBrick rom. It takes about 5 seconds and lef flashes quite fast during this period.
Although for the 2nd and 3rd SBricks that I tried the upgraded it didn't start for sometime (it was obviously too much).
Since the critical part is the final one when it flashes the rom, I was not affraid to disconnect SBrick in the middle, power it down and restart the fw upgrade procedure.
The 2nd time it ran always fine and fast. :)
