Hello,
Question: what are the differences among multi-stm-ppm-taer-vxxxxxx.bin, multi-stm-ppm-aetr-vxxxxxx.bin and multi-stm-ppm-reta-vxxxxxx.bin?
I supposed related to the radio channel order setup, but i tested on Turnigy 9x with Er9X and all three require AETR.
Is that correct?

Feedback: on "Flysky TH9X family of transmitters" page, point 6 with STM module, after connection has been established the red LED is solid ON.

Thank you so much for sharing your talent and time!
