Fixed ID
If you used a Fixed ID with the original Walkera firmware you must clear the Fixed ID in the Receiver with the Bind Plug.
If you don't clear the Fixed ID the model will not bind.
If you want to use a Fixed ID you can enter the same Fixed ID you had for the original Walkera firmware.
Example: Your original Walkera firmware Fixed ID was: 123456
Assign the Deviation Fixed ID: 123456
You can also assign any Fixed ID that you want to use. You don't have to use the original Walkera firmware Fixed ID. Clear the Fixed ID in the Receiver
with the Bind Plug then assign any Fixed ID that you want to use.
