I've been trying to get the SUOTA tutorial for the DA14531 to work on a Pro Dev Kit with DA14531MOD daughter board, but I keep getting the error "Same Image Error" when trying to do an update from an android phone with the Dialog SUOTA app.
http://lpccs-docs.dialog-semiconductor.com/Tutorial-BLE-SUOTA-DA145x/bui...
I've repeated the entire process twice now, but is fails every time. I did implement the hardware and software setup changes required for the module as specified in section 4.3
Any recommendations/advice? Has anyone else experienced a similar issue?

HI DanieCML,
Thanks for your question and for your interest in our BLE solutions.
The tutorial is missing a step - we are working on that. You will need to modify the sdk_version.h file and have 2 different files : fw_1_version.h and fw_2_version.h
When creating the single image – “make single image” – figure 7, you first need to check that the sdk_version.h file is up to date. The sdk_version.h can be found under the following path:
C:\Program Files (x86)\SmartSnippetsToolbox\SmartSnippetsToolbox5.0.14\common_resources\SupportPackages\DA1453x\toolbox_resources\common\sdk_version.h
When creating the second .img file - “make single image” , the sdk_version.h file should be modified again in the same location, in order to have a newer revision number.
I suspect that the “same image error” is due to the same sdk versioning.
I would also recommend using the latest version of SmartSnippets Toolbox (SST) which is version 5.0.14- can be found om the support website.
