New features included in this release:
1. Modified the calculations that determine altitude from the accelerometer. Previously, those calculations were limited to a maximum altitude of 410K feet. That limitation has been eliminated.
2 . The downlink data packet format has been modified so that it is now possible to report altitudes above 524K feet. For this to work, the Mx120 receiver must also be updated to firmware version 3.2 or later. Note: this change is backwards compatible and will still work just fine with older versions of receiver firmware provided the maximum altitude stays below 524K feet. The TelemetryPro Flight Data Analyzer software program must also be version 3.2 or later in order to handle altitudes above 524K feet.
3. Modified the launch detection criteria so that it no longer triggers if the rocket is raised or lowered AFTER arming the system. Previously, a false launch detection would occur if the user armed the system and then raised or lowered the rocket. It was then necessary to reset the whole system and start over. That problem has been eliminated. However, the rocket must remain vertical and undisturbed for at least 30 seconds prior to actual launch. This is necessary to make sure an automatic accelerometer calibration process has completed.
It is still best practice to arm the system AFTER the rocket is vertical. Then disarm the system first, if it becomes necessary to lower the rocket to work on it. However, with this change, there should be no harm done if the user forgets this procedure.
