SUOTA from central mode

Hi

I am trying to implement a SUOTA initiator into a central mode application on a DA14585. In one of your application notes you are referencing another application note, AN-B-003_1, which could shed some light on the SUOTA/SPOTA process, but I can't seem to find it anywhere. Can you help me find it, or maybe provide another document that specifies how SUOTA should work?

Thanks.

BR,

Tommy

Hi tplux42,

Hi tplux42,

请看看Tutorial 6: SUOTA example for DA14585/6document from our support website, and you will find all the information you need regarding the SUOTA functionality.

Thanks, PM_Dialog

Hi,

Hi,

I already read this document, but it doesn't provide any specification of the SUOTA process, as I see it. I'm looking for documentation specifying e.g. the different SUOTA commands, so that I can make a SUOTA client - I already have an application running as SUOTA host.

I've also looked through the "Initiator" example in the SDK, but I still can't figure out how this works, let alone how to incorporate it in the application that's supposed to run as initiator.

Can you help me along in any way?

BR, Tommy

Hi tplux42,

Hi tplux42,

Τhe AN-B-003 document was based on SDK3 which is a very old version of SDK is and it’s not currently available. There is not any available document describing the SUOTA specification. However, can you please provide me more inputs for what you would like to accomplish? In which version of SDK are you working on?

Thanks, PM_Dialog

Hi again,

Hi again,

We are working with SDK 6 (6.0.10.511).

We have an advertising device with the DA14585 which supports SUOTA. In a similar device we have implemented the central mode application. This device is connected to a linux device through the uart, so that the linux device can send proprietary commands to the DA14585 to start scan, connect and send data through bluetooth to the advertising devices.

Now, we would also like to be able to execute a SUOTA update of the advertising devices from the central mode device. So I need to know what to send from the central mode device to the advertising device.

I hope this makes sense.

BR, Tommy

Hi Tommy,

Hi Tommy,

This might not be a straight-forward implementation. You have to read how the SUOTA service is implemented. Probably in the SUOTA mobile application you will find which commands are sent in order to perform software update. CodeLess is a related reference design and you could send AT commands over UART, but it does not support SUOTA commands.
