I'm trying to bind an Eachine Trashcan that I just got with the built in spektrum receiver to a Jumper T16.  I can't get the Trashcan into bind mode.  I set my serial port to UART2 and selected the Spektrum 2048 receiver in configuration (I tried the 1024 as well).  I go to the CLI and type "set spektrum_sat_bind=9"  I have also tried =5 and then I type save and enter.  I unplug wait a couple seconds and plug in.  None of the lights change and the only light that is on the underside of the drone is a blinking green light.  I have bound with an Eachine QX65 using the same procedure and 2 red and 2 white lights blink and then I can bind, but that does not happen here and the directions are the same.  I am using the "CRAZYBEEF4DX (LEGACY) VERSION 4.0.0"  I have also tried the 3.5.7 and the 4.1.1.  Also, there was a "CRAZYBEEF4DX (HAMO)" version that I tried as well.  Is this user error or a bad receiver?  (I'm a beginner)  I ran out of google searches to do, so I was hoping someone has had this problem in the past or would know how to troubleshoot.
