Cable-64k option(profile) not working.

I have tried it with both android and ios device and cable -64k mode not working.
I have added two android device like attached image.

Do other modes work in this configuration? Do ultrasonic modes work?

Cable-64k is pretty aggressive. It's hard to guess what exactly is happening, but you might have luck increasing the ofdm.left_band and ofdm.right_band by a few each for that profile (in quiet-profiles.json). If that doesn't work, try bumping mod_scheme down to qam512 or qam256.

Yes other modes working, ultrasonic also.
Android to android working fine but android to ios and ios to android not working smoothly.
for that kind of issue i think if cable-64k will work but it is not working, i have tried all options as you suggested (mode256 , mode512 etc.) but nothing work.
Is it(cable-64k mode) working at your end?
