For those who want to tweak low-level RF parameters (spreading factor, coding rate) beyond the standard GUI:
git clone https://github.com/your-org/ltu-rocket-firmware
cd ltu-rocket-firmware
Open the folder in PlatformIO. Select your board environment (e.g., env:ltu-v2). ltu-rocket firmware
Once the ltu-rocket firmware is successfully installed, you must configure the parameters. Connect via Mission Planner’s SiK Radio screen and set the following: For those who want to tweak low-level RF
| Parameter | Professional Setting | Explanation | | :--- | :--- | :--- | | Air Speed | 64 kbps | Balances range and bandwidth. 32kbps for extreme range (<10Hz updates). | | Tx Power | 20 dBm (100mW) for ground; 30 dBm (1W) for air | Saves ground battery; complies with EIRP limits. | | ECC | Enabled | Forward Error Correction adds 10% to range at 5% bandwidth cost. | | Op Resend | Enabled | Ensures critical MAVLink messages (RTL commands) are repeated. | | Max Window | 33 | Allows more data bursts for high-speed quads. | Open the folder in PlatformIO
