Important Instructions on Promotion to MK32 / MK15 Communication Range and Video Fluency
In order to have the best communication range and video fluency with MK32 / MK15 system, please carefully read the below tips for antenna options, antenna setup, and link configuration.
General Precautions
- It is suggested that not to run SIYI FPV app and QGroundControl app simultaneously with video streaming, not even running one at backstage, as it still occupies bandwidth thereby lower the communication range.
- Only power batteries are allowed to power the XT60 connector on MK15 air unit. HD image transmission requires very high standard to the current of power supply, the instancy of the current response, and the current ripple. Power supply from the third-party / modified BEC or from PDB may interfere the link stability and the communication range. If you do not need the BEC, it is suggested that you use the HM30 air unit.
- The default decode type of SIYI FPV app should be hardware decoding. Software decoding may increase latency.
General Antenna Options and Wireless Mode Configuration for Different Range
to 10 Kilometers Range
Two standard omni antennas on ground unit.
Wireless mode: 5 km or 8 km low latency.
to 15 Kilometers Range
Two standard omni antennas or two standard long-range antennas on ground unit.
Wireless mode: 15 km GCS.
to 30 Kilometers GCS Flight
Two standard long-range antennas or higher gain patch antennas on ground unit.
Wireless mode: 24 km GCS.
4.Signal is weak on top of the standard omni antenna. When the aircraft is flying on top of the ground unit, flying altitude should be lower than 100 meters as less as possible.
5.When the ground unit is working with long range antennas or patch antennas, the aircraft should always be in front of the antenna panel instead of being vertical of the antenna or on opposite.
6.Only the standard omni antennas are suggested for the air unit. If your aircraft is too small to mount the omni antennas, or you worry about the weak signal of the top part, then you can consider using SIYI lollipop antennas. Lollipop antennas performs shorter range than the standard omni antennas.
How to Place the Standard Omni Antennas on Ground Unit1.The SMA connectors should be screwed tightly.
2.The antennas should stand vertically from the control panel of the ground unit, and the antennas’ flat side should always point to the aircraft or the vehicle.Do not cross or overlap the antennas during mission.
.
3.The distance between two standard omni antennas on ground unit should be 10 cm, at least not less than 5 cm, otherwise the signal quality will be bad.
How to Place the Long-Range Patch Antennas on Ground Unit
1.The SMA connectors should be screwed tightly.2.Long-range patch antennas are directional, which should always be pointing to the aircraft during flight.3.When you are using SIYI standard long-range antennas, please make its short side be parallel with horizon and its long side be vertical of the control panel to get the best signal quality.4.The distance between two standard omni antennas on ground unit should be 10 cm, at least not less than 5 cm, otherwise the signal quality will be bad.
MK32 User Manual V1.0
How to Place Air Unit Antennas
1.The SMA connectors should be screwed tightly.

Function Type: Switch the function between “RC Relay” and “Dual RC” and switching between “TX-A” and “TX-B” at the same time.
Bind: Bind “TX-A” and “TX-B” with the air unit in turns after configuring function type. Control Switch: Define a button or a switch to take over control in “RC Relay” mode, or to switch control of certain channels between “TX-A” and “TX-B” in “Dual RC” mode. Control Channel: In “Dual RC” mode, define channel mapping for TX-A and assign channels to TX-B according to your requirement.
RC Relay
RC Relay function is specially developed for very long-range drone flight. In this mode, two ground units can relay control through the same air unit to reach twice of the range limit of a single system. The function can be widely used in enterprise drones for inspecting power lines, drone delivery, and cargo shipping.
Steps
1.Prepare two MK32 Dual versions.
2.Go to “Multiple Links – Function Type”, assign the two ground units as “RC Relay TX-A” and “RC Relay TX-B”.
- Bind “TX-A” and “TX-B” to the same air unit in turns.
- In “Control Switch” page, assign a switch / button / dial to switch control of the air unit from “TX-A” to “TX-B”.
5.RC Relay settings are finished.
Dual RC
Dual RC function is developed for certain enterprise applications. In this mode, two ground units control one air unit. One ground unit can be assigned to control drone motors, and the other ground unit can be assigned to control payloads / gimbal / servos.
Steps
1.Prepare two MK32 Dual versions.
2.Go to “Multiple Links – Function Type”, assign the two ground units as “Dual RC TX-A” and “Dual RC TX-B”.
3.Bind “TX-A” and “TX-B” with the same air unit in turns.
4.In “Control Switch” page, assign a switch / button / dial to switch control to the air unit from “TX-A” to “TX-B”.
5.In “Control Channels” page, configure channel mappings for “TX-A”, then assign the decided channels to “TX-B”. Thus, when the Dual RC function is enabled, “TX-A” can authorize to “TX-B” or withdraw from “TX-B” the control of the assigned channels.
6. Dual RC settings are finished.
Mark
Dual RC function works similarly to Wireless Coach function. Thus, MK32 Dual versions can also be used for drone training and education.
DANGER
When Dual RC function is enabled and “TX-A” lost control to the air unit, “TX-B” will lose control to the air unit, either.

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.
