Some users may experience issues when using the Rowsfire A107 Overhead Panel together with other flight simulation hardware and software. Typical symptoms include:
-
The A107 panel does not respond in MSFS2020
-
Rowsfire App and MobiFlight cannot run at the same time
-
After updating firmware, MobiFlight asks to reload Arduino
-
Uncertainty about whether Rowsfire App and MobiFlight should run together
In most cases, this is not a hardware problem, but a COM port conflict.
1. Symptoms
Users often run a complex setup including multiple devices such as:
-
WinWing hardware (EFIS / FCU / Throttle / MCDU)
-
Thrustmaster joystick
-
StreamDeck
-
Logitech rudder pedals
-
Rowsfire A107 Overhead Panel
At the same time, several software tools may be running:
-
Rowsfire App
-
MobiFlight
-
WinWing SimAppPro
-
StreamDeck Software
This can lead to:
-
The panel not responding
-
Software failing to connect to the device
-
Controls not working in MSFS
2. Cause
The most common reason is a COM port (Serial Port) conflict.
The A107 Overhead Panel communicates through a USB serial port. If both:
-
Rowsfire App
-
MobiFlight
try to access the same COM port, Windows will only allow one program to connect at a time.
The other program will fail to communicate with the device, which can appear as if the software is incompatible.
3. Solutions
You can use one of the following setups.
Option 1: Use the Rowsfire App
Recommended startup order:
-
Start Rowsfire App and connect the A107 panel
-
Confirm the connection is successful
-
Start other software such as:
-
WinWing SimAppPro
-
StreamDeck Software
-
-
Launch MSFS2020
Important:
If you are using the Rowsfire App, do not allow MobiFlight to connect to the same COM port.
Option 2: Use MobiFlight Only
If you prefer using MobiFlight:
-
Do not run the Rowsfire App
-
Control the A107 panel using MobiFlight with the MCC configuration file
4. Summary
If the A107 Overhead Panel is not responding in MSFS, the issue is usually caused by:
Multiple programs trying to access the same COM port.
To resolve this:
-
Use either Rowsfire App or MobiFlight to control the A107 panel
-
Avoid having both programs connect to the device at the same time
-
Adjust the software startup order if necessary
