Receiver configuration
We have configured the DSM2/DSMX receiver for the Mobula7 HD before shipping. If you
flashed the firmware ,Please setup as the following steps: Enable Serial_RX for UART2, then
select RX_SERIAL from the RECEIVER Mode and set the Serial Receiver Provider to be
Spektrum1024 for DSM2 radio and Spektrum2048 for DSMX Radio in Betaflight Configurator.
2.For most of Spektrum radio the default channel 5 is Gear switch and you can also customize
it. Use DX9 for example, Go to menu and select System setup ,then choose Channel ssign.
1.Plug the USB and connect to betaflight configurator, from the CLI tab type: "set
spektrum_sat_bind=9" for DSMX radio or "set spektrum_sat_bind=5" for DSM2 radio.
2.Type "save" and after Flight controller reboot then remove USB plug(=Power off the board)
3.Wait a second and reconnect the USB cable . After cold start the orange LED on the receiver
should start blinking and transmitter should be turned on while pressing the bind button.
4.After binding the orange LED on the receiver should be solid. Connect to Betaflight and use
receiver tab to test that satellite receiver is working correctly.
5.Final step is to go to CLI tab and type "set spektrum_sat_bind=0" and then type "save". This
must be done so that satellite receiver doen't go back to binding mode when the flight
controller is repowered again.

Set vtx_band=3
Set vtx_channel=1
Set vtx_freq=5705
save
Notes: The vtx_freq should match the vtx_band and vtx_channle as the VTX Channel list shows.
For example, if you set vtx_freq=5732, you should set vtx_band=5 and vtx_channel=3
