Have a miniquad with BLHeli ESCs and a PX4 FC. How to pass through for PX4?
I am afraid under current releases it is not possible.
What is your specific requirements about pass through?
I have an aircraft with a pixhawk mini and cicada 30a BLHeli ESCs. I want to calibrate the ESCs and flash them with latest firmware so I can get the quad in the air. I tried using all the pass throughs with BLHelli suite to connect my FC to the ESCs. Did not work though. “Loaded” infinitely or stopped responding all the time.
How do I approach this problem. I will be using q ground control as a mission planner and intend to have PX4 flashed. Am a n00b with PX4 so all help appreciated.
Thanks in advance! 
QGC can calibrate BLs, but cannot update ESC firmware yet. So you still have to use BLHeliSuite to flash and tuning ESC params.
Or get a programming card from your ESC vendor would be easier before PX4 can support that.

Good day,
I’ve built a new 250 fpv quad… before flying i need to know if the hobbywing 35a esc with blheli firmware are compatibles with px4 firmware 1.7.3.

Hi, ralandash, it would be very handy to have the BLHeli pass-through support to tune the ESC parameters. Do you guys have any plan to develop this feature?
Than you very much.
