DATALINKS

Datalink is one of the core features of most SIYI radio systems.

MK32 ground unit supports communication with multiple ground control software through various hardware interface.

Communication with GCS through UART (Taking JIYI Agri-Assistant as an Example)

Let’s take JIYI Agri-Assistant as an example.

1.In “SIYI TX” app, go to “Datalink”, and choose “UART” in “Connection”, “JIYI (K3A / K++)” in “Flight Controller”, and “57600” in “Baud Rate”.

2.Run JIYI Agri-Assistant, the application will pop up a window for datalink connection options, choose “MK15” and “OK”.

3.After confirming, remote controller will communicate with JIYI app automatically and shows “device connected”. Datalink connection is established.

Mark

SIYI links also support datalink connection to JIYI Agri-Assistant through USB COM and

Bluetooth.

Communication with GCS through USB COM (Taking QGC as an Example)

Let’s take QGroundControl as an example.

1.In “SIYI TX” app, go to “Datalink”, and choose “USB COM” in “Connection”.
2.Open QGC, the software will pop up a window to ask if “Allow QGroundControl to access CP2102 USB to UART Bridge Controller?” Check and touch “OK”.

3.The top progress bar in QGC starts to move, which means the remote controller is trying to communicate with QGroundControl. After that the datalink connection will be established.

Mark

SIYI links support multiple baud rates. This guide uses common baud rate “57600” for your reference.

If it is your first time adding a new connection in QGC, please do not check the option “Automatically Connect on Start”. It can be checked later when you confirm that the datalink is connected successfully.

4.3 Communication with GCS via Bluetooth (Taking QGC as an Example)

Let’s take QGroundControl as an example.

1.In “SIYI TX” app, go to “Datalink”, and choose “Bluetooth” in “Connection”.

2.In Android OS, go to “System Settings – Bluetooth”, search the Bluetooth device with the same ID shown in “Device ID” (“SIYI 68********”), and pair.

3.Open QGC, go to “Application Settings” page, touch “Comm Links” and “Add” a new connection.

4.Set the type as “Bluetooth”, then touch “Scan”.

5.Touch the Bluetooth device of which the name is starting with “SIYI-XXXXXXX”, then touch “OK” to go back to the Comm Links page.

6.Touch the configured “Bluetooth” connection and touch “Connect”, Bluetooth connection is finished.

Mark

Step 1 and 2 have been finished before delivery.

If it is your first time adding a new connection in QGC, please do not check the option “Automatically Connect on Start”. It can be checked later when you confirm that the datalink is connected successfully.

Communication with Windows GCS through Type-C (Taking Mission Planner as an Example)

Let’s take Windows Mission Planner as an example.

1.In “SIYI TX” app, go to “Datalink”, and choose “Type-C” in “Connection”.

2.Connect MK32 ground unit’s bottom Type-C port to the Windows computer. MK32 ground unit will pop up a window saying “Type-C is plugged in, disable video stream to enable Type-C data transfer?”. Tap on “Cancel” and the Windows computer will generate a communication port for MK32 ground unit.

3.Run Mission Planner on Windows and select the relevant port and baud rate for the connection. Then click to connect.

4.Wait till the connection is established.

4.5 Communication with GCS through LAN by UDP (Taking Windows QGC as an Example)

Let’s take QGroundControl as an example.

1.Configuring MK32 ground unit’s Android static IP addresses is necessary before establishing the connection to avoid IP addresses conflict with the Windows computer. Open Android settings on MK32 ground unit, go to

“Network & Internet – Ethernet – Setting Ethernet”. Change the IP addresses to

“192.168.144.19”.

2.Connect MK32 ground unit’s bottom LAN port to a Windows computer’s RJ45 port. Then go to Ethernet settings in Windows settings.

3.Go to “Internet Protocol Version 4 (TCP/IPv4)” and change IP addresses as below. Then confirm.

4.Run Windows QGC and go to “Application Settings” in QGC, click “Comm Links” and “Add” a new connection.

5.Name the connection as “UDP”, set the type as “UDP”, the port as “19856”, the server address as “192.168.144.12” and “Add Server”, then click “OK” to return to the Comm Links page.

Mark

MK32 ground unit can also output video stream to PC GCS through the LAN port. That is to say, the MK32 link can also work as a transparent link to establish communication between a ground computer and an onboard computer.

If it is your first time adding a new connection in QGC, please do not check the option “Automatically Connect on Start”. It can be checked later when you confirm that the datalink is connected successfully.

Solutions to Disconnection

If SIYI system failed to establish datalink connection with GCS, please try to follow the steps below to investigate possible reasons.

1.Confirm if the ground unit is bound with the air unit.

2.Confirm if the air unit is connected to the flight controller through telemetry cable.

3.In “SIYI TX” app, go to “Link Status” page to check connection status between the ground unit and the air unit. When connection is normal, data “download” is not 0. If it is “0”, please go back to check step 1 and 2.

4.Then go to “Datalink” page in SIYI TX app and check:

If “Connection” is correctly configured?

If “Flight Controller” is correctly configured?

If “Baud Rate” is correct when you use customized flight controller.

In your GCS, check if “Datalink” port is correctly configured.

5.If the flight controller is from Pixhawk family, please try to switch telemetry cable connection between the TELEM 1 port and the TELEM 2 port.
