1. Overview of Receiver Update (Reading Required)
The RF systems of Flysky AFHDS3 series products have been upgraded to version 3.0. If your transmitter (including RF module) fails to bind with the receiver, you can perform the upgrade or rollback of the RF library by referencing to the tutorial.
You can perform the upgrade in three modes: Mode 1: Receiver firmware update package delivered in the transmitter; Mode 2: Flysky Assistant; Mode 3: Receiver updater. For the standard receiver of the transmitter, Mode 1 is recommended. For a non-factory standard receiver, Mode 2 is recommended (Flysky Assistant). For users who cannot register in Flysky Assistant, Mode 3 is recommended. The effects of the 3 update modes are the same.
The software version matching relationship between the transmitter and the receiver is as follows:
Figure 1.1 Firmware mapping relationship between transmitter and receiver
Note:
1、The firmware version of the receiver in this table is the latest version provided by Flysky Assistant 3.0 and receiver updater, at present. Except for versions in this table, other firmware versions can be used normally by users if receivers can bind with transmitters.
2、The green background is RF system version 3.0, and the yellow background is RF system version 2.0.
2. Update Steps for each Receiver
