Hi, I'm using Sentinel drone. For some reason RC apparatus stopped working and i can't bind it again.
When i'm trying to set up bind mode nothing happens. I was following this guide :
https://docs.modalai.com/sentinel-user-guide-pre-flight-setup/

Led is blinking always slowly on blue....

What can i do about it ? 
I'm using out-of-the-box commando8 (included with Sentinel drone). 

Why this could happen ? 

Thanks for help

If any1 will have similar problems in future don't follow guide : https://docs.modalai.com/sentinel-user-guide-pre-flight-setup/

See those docs : https://docs.modalai.com/voxl-elrs/
All You need to do is voxl-elrs -b, then on aperture go to ExpressLRS and choose bind :)
