readUserBackupRegister

Hello everyone –

Does anyone have example code that they can share showing the use of read and write user backup register? I can’t get it to work right.

                    if ((ret = dot->writeUserBackupRegister(0, sleeptime)) != mDot::MDOT_OK){ 
                            pc.printf("Failed to write sleeptime\r\n"); 
                        } else {
                            pc.printf("Wrote sleeptime\r\n"); 
                        }

I’m trying to save my sleep time of dot->sleep(sleep_time, mDot::RTC_ALARM); between sleeps.

Thanks for any advice. I know C++ only enough to be dangerous.
