title_body: Taranis X9D Plus 2019: Switches SE,SF,SG,SH, and SI are not working/responding on Betaflight So switches SA,SB,SC, and SD work on Betaflight. Aux channels 1 through 4.
  But switches SE,SF,SG,SH, and SI are not working/responding on Betaflight. Aux channel 5 through 9, I believe
  I am using TBS Crossfire lite, with crossfire nano receiver.
  On my Taranis I have already setup Mixers to activate all switches and nobs.
  When I first binded to my reciever I did not set up the rear switches(SE,SF,SG,SH, and SI), but I already  setup 3 of the front switches(SA,SB, and SC) before binding to my model.
  Things I have tried:
  
  Connected Taranis via usb mini, opened Devices and Printers on windows and ran through the wizard to re-setup my Taranis
  Reconfigured my Input and  Mixer page on my defined model. Simply defined each switch in order in the Inputs page, and then on Mixer page defined the channels
  Rebinded my crossfire transmitter receiver by holding down the button and plugging in my battery to the quad. Releasing the button on the receiver and pressed and held the button till it binded again and  updated again. This time my model was setup but same results
  On Taranis, long pressed MENU and went to page HARDWARE: ran calibration and also Debuged switches. Everything seems normal
  
  Considerations:
  
  I have the latest Betaflight-configurator and I am using the latest Beta-flight firmware on my quad
  
  Flight Controller: STABLE PRO F7, Model:STABLE PRO F7 35A
  
  Transmitter Receiver: TBS crossfire nano
  
  Everything else works as expected
  
  This is occurring with two of my first-build quads
  
  Followed this reference to solder and config the transmitter receiver: https://geprc.com/download/en/GEPRC-STABLE-PRO-F7-DUAL-MANUAL-V1_0.pdf
  
  Taranis is in 1-16 channel mode. Also I am not missing switches, all are activated, I checked in the HARDWARE's page
  
  Taranis Firmware: opentx-x9d+2019, version: 2.3.6
  
  How my Mixer is setup:
  CH1 Rud
  CH2 Ele
  CH3 Ail
  CH4 Thr
  CH5 SA
  CH6 SB
  CH7 SC
  CH8 SD
  CH9 SE
  CH10 SF
  CH11 SG
  CH12 SH
  CH13 SI
  CH14 S1
  CH15 S2
  CH16 LS
  CH17 LR
  
  
  Any suggestions would be much appreciated.
upvoted_answer: The issue was on my Crossfire Nano receiver. I had to change the operation mode from 8 channel to 12 channel. Now switches from SE - SH work. Even though I defined all my knobs, switches, and button on my Taranis, I am limited to 12 channels from my crossfire nano receiver(4 channels for the sticks, 4 for front switchers, and 4 for top switches).
