4.7 Solutions to Disconnection

When the remote controller is in good communication with the air unit, but it fails to

establish datalink connection with GCS, please try to follow the steps below for

troubleshooting.

1. Confirm if the air unit is wired to the flight controller by correct telemetry cable.

2. If you are using a customized telemetry cable, please check:

⚫ If cable pin map is correct?

⚫ If the TX and RX pins in the flight controller and air unit telemetry port are

swapped?

3. In “SIYI TX” app, go to the “Link Status” page to check communication status.

When the communication is good, “data download” is not 0. If it is “0”, please go

back to check step 1 and 2.

4. In “SIYI TX” app, go to the “Datalink” page and check:

⚫ If “Connection” is correctly configured?

⚫ If “Flight Controller” is correctly configured?

⚫ If “Baud Rate” matches with your flight controller?

⚫ In the GCS, check if the datalink settings are correctly configured.

5. If it is PX4 / Ardupilot open-source flight controller, please try to switch telemetry

cable connection between the TELEM 1 port and the TELEM 2 port on flight

controller.

6. If both the remote controller and air unit are the latest firmware?
