New features included in this release:
1. An operator can now increase the transmit power used prior to liftoff. Normally, the transmitter sends out data packets at 100mW prior to liftoff. Once liftoff occurs, the power is automatically increased to 500mW or 1W depending on the altitude and distance. By allowing the power used prior to liftoff to be increased, it is now possible for a receiver to be much further away from the rocket at liftoff and still maintain a solid downlink connection. This is really only needed if a receiver will be stationed more than a mile away from the launch pad. Which is usually only the case if a second or third receiver are stationed far away in order to help track a really high flight. The standard 100mW power settings is plenty for all other situations. It saves battery power and helps avoid overloading the receiver with too high a signal strength.
This new capability is also useful for ground testing to make sure other electronics located near the TelemetryPro transmitter will operate correctly even when the TelemetryPro transmitter is transmitting at full power.
The transmit power used prior to liftoff is adjusted in the TRANSMIT POWER menu on the receiver. The receiver must also be running firmware v3.1.0 or later. The TRANSMIT POWER menu is accessed on the receiver from: MAIN MENU --> LAUNCH --> RADIO LINK --> ADVANCED SETTINGS
2. Modified the algorithm that detects a shred so that it can also detect other flight anomalies at lower speeds such as a motor burn-through failure.
3. Lowered the altitude threshold for detecting the main parachute deployment charge fired. It was previously looking for the deployment event as high as 10,000 feet. That seems unnecessarily high. Lowered it to 5,000 feet just to avoid any false triggers up high from parts of the airframe "clanging into each other" during descent. I doubt anyone will ever need 5K but 2K or 3K is not uncommon at Black Rock.
