Symptom:
One Device at a Time: Ensure the Rapsodo MLM2PRO app is not actively trying to run a practice session while you are opening E6.
Same Network: If you are playing on a PC, your PC and your phone must be on the same Wi-Fi network.
Turn on your MLM2PRO and connect it to the Rapsodo MLM2PRO app on your mobile device.
Navigate to the Play tab > Simulation > 3rd Party Apps.
Select E6 CONNECT (this remains the authentication path for the 2026 version as well).
Tap Authenticate Now. Wait for the "Success" or "Authentication Successful" message.
Important: Once successful, you may close the Rapsodo app, but do not turn off the device.
From the Main Lobby, click the E6 Icon (Global Menu) in the top-left corner.
Select Tracking Systems.
Find Rapsodo in the list of integrated devices and click Connect.
The system should detect the unit within 10 seconds. The status will turn Green once active.
The 7.5-Foot Rule: For the new 2026 Club Data metrics, place the ball exactly 7.5 feet (230 cm) away from the unit.
Ball Choice: To get accurate spin and spin axis in E6, you must use the Callaway RPT balls provided with the unit. In the E6 Configuration menu, ensure "Rapsodo Ball" is selected.
Firewall Blocks: If you are on a PC, ensure E6 Golf 2026 is allowed through your Windows Firewall for both Private and Public networks.
Bluetooth/Wi-Fi: Ensure your device has both Bluetooth and Wi-Fi enabled. If using a PC without built-in Bluetooth, a Bluetooth 5.0 USB adapter is highly recommended.
