Hello all,

I am having problems binding my Sentinel to my transmitter. I have run qrb5165-bind with the -t, -f, and -s options and have had "success" binding the transmitter to the receiver as I get a solid orange light on the receiver. The receiver I have on the drone is the Spektrum DSMX.

The problem is, after power cycling everything and restarting QGroundControl, QGroundControl doesn't see any radio channels. I have pulled the Spektrum receiver off of the sentinel and plugged it into another one of my drones and I had no problem seeing all of the channels through QGroundControl. I have checked the physical connections of everything and it's all solid. Any advice?

@modaltb Thanks!

Finding the correct mixer file solved my problem.
Thank you!

Hello all,

I'm having a problem getting the VOXL2 to spin all 6 motors of my hexarotor. I am able to spin 4 motors without a problem, but not all 6. I have, what I believe, everything hooked up correctly. J19 of the VOXL2 pins 9-12 are hooked up to VOXL2 IO J4 pins 1-4, VOXL2 IO is hooked up to the PWM breakout where I have all 6 motors hooked up (I've tried different configurations of connections to verify the motors/ESCs are okay), and I have the Spektrum receiver hooked up and bound to my transmitter.

I have PX4 firmware 1.4.26beta running onboard the VOXL2 and I it looks like the VOXL 2 IO board is running just fine. I have a solid green LED, 2Hz blinking blue LED, and an OFF orange LED. I have changed the mixer file quad_x_io.main.mix (which I had to create as I couldn't find the file) to contain the following: R: 6x 10000 10000 10000 0.

I'm unsure if I have the firmware flashed correctly on both the VOXL2 and the VOXL2 IO board; I was looking at this webpage and I'm a little unsure about the instructions and if this may be what the problem is since I really haven't run many of the commands.
Thanks.

@Chad-Sweet I am also looking for a Voxl2 IO. My project has come to a halt without it.
