So I came across an issue while working on developing an app that can update firmware OTA. I was using Nordic Semi - android DFU Library
implementation 'no.nordicsemi.android:dfu:1.11.0'
But everytime I ran the app, we are able to select the file for update as well as the device but when we click the upload button - the app crashes with the following error.
I am attaching the log below, if anyone can kindly let me know where I am going wrong that would be amazing!
