How to set up your receiver in Betaflight configurator on SpeedyBee F7MINI flight controller? – SpeedyBee

Please follow these steps:

Step 1: Please check whether the wiring between the receiver and the flight controller is correct.

It is recommended to refer to the wiring diagram in the manual of the flight controller to connect the receiver. Take the SpeedyBee F7 mini flight controller as an example, you could refer to the following diagram.

Note 1: The signal wire(s) of the receiver should be correctly connected to the flight controller. For an SBUS receiver, connect the SBUS signal of the receiver to a free RX pad(instead of a TX pad) of the flight controller. For a TBS crossfire/ELRS receiver, you should connect RX on the receiver end to a free UART's TX pad and connect TX on the receiver to the UART's RX pad.

Step 2: Make sure the receiver is successfully bound to your radio transmitter

We suggest you refer to the receiver's manual and the transmitter's manual to verify if they are bound.

For example, the following video shows the Radiomaster Zorro transmitter's binding process:

Step 3: Check if the 'Serial Rx' is enabled for the receiver

For example, if your receiver is connected to UART 1, then you should enable 'Serial Rx' on UART 1.

Note: You can only enable one item in the whole UART row because one UART can only connect one peripheral. For example, if you set UART 1 as Serial Rx, you can't enable configuration/MSP, Telemetry Output, Sensor Input, or Peripherals.

Step 4: Set the correct receiver mode and provider.

You should do this due to your receiver's manual:

TBS Crossfire – CRSF
ExpressLRS – CRSF
Spektrum DSM2 – SPEKTRUM1024/SRXL2
Spektrum DSMX – SPEKTRUM2048/SRXL2
FrSky RX – SBUS
Futaba RX – SBUS
FlySky RX – IBUS
Turnigy RX – IBUS

For example, if your receiver is TBS Crossfire or ELRS, please choose 'CSRF'

Choose 'Serial(via UART)' and 'SBUS' for Frsky receivers:

Choose PPM or IBUS for Flysky receivers:

如果设置完接收方协议后，接收方通道全部变成白色（如下图）。

请检查使用的固件版本是否高于 Betaflight 4.4.0。

Betaflight 4.4.0版本更新了Cloud-Build功能，刷入固件前需要提前选择接收机协议（默认接收机协议为SBUS、CRSF、GHST）。

具体刷机方法可以参考以下文章：

如何正确刷写 Betaflight 4.4 固件。

Step 5: Check if your transmitter can be detected in the Betaflight configurator.

Connect your flight controller to the Betaflight configurator > Receiver tab, move the sticks or toggle the switches to see if the Betaflight UI can show the input correspondingly.

NOTE： for some receivers, you must keep them at least 0.5 meters far away from the transmitter to prevent the connection from being disconnected automatically.
