What do I need for software updates (DFU) via BLE?

Hugo Habicht

Hello,

we would like to update our application software. There is plenty documentation from Nordic all over the place, some relevant, some outdated, with boot loader, without, a BLE DFU service a.s.o. but we could not find any top level documentation what you really need. I do not want examples because our software is pretty much finished.

So what I would like to know is:

1. what do I need on the BLE peripheral side to do over the air application software update (we don't care about softdevice update and if it's possible without bootloader the better).

2. What do I need on the phone / desktop side? The nrfTollbox seems to have a DFU function but I could not get that to work; the file select leads to some obscure file manager download which eventually fails. I downloaded the nrf-connect (great name btw., same as you sdk now) for desktop and it works fine with an pca10056 DK but the desktop software does not seem to have any DFU built in. Have I missed that or is there an nrf-Toolbox for desktop available?

I have the feeling it's very easy and it's all there but I just cannot see it.

Kind Regards,

Parents

    No, it wasn't in. But I get the same "macro 'SVCI_DECL"" error message when it is defined (I had taken it out to see if that makes a difference).

    To be honest: this is really frustrating, no proper documentation, not even a single sentence with most of their thousands of functions, about 5% of the infocenter links are dead (strangely enough always the ones I need), just sample code with an unbelievably bloated sdk and you can pull tiny fragments of information out of this forum.  I do not see this leading anywhere, this does not give me any confidence getting a reliably working product. I am tempted to pull the plug and start again; this time I will select the hardware manufacturer and not the customer and I will have a good look at their software first. How much market share in bluetooth devices does nordic have again?

    And once I'm at it: if one of my engineers would produce 9300 character long compiler commands with ../../../../../../ all over the place I would certainly send him back to engineering school.
