I think I am in the same boat. I have been trying to install Jasager on a Ubiquiti Bullet.
I know other people have mentioned they have successfully done so, but I wonder how?
When I get to the part of installing jasager I get stuck with the kmod gpio:
opkg install jasager_2.1-1_mips.ipk
Installing jasager (2.1-1) to root...
Collected errors:
* ERROR: Cannot satisfy the following dependencies for jasager:
* kmod_gpio *
I have backed up and installed older versions of open wrt on the bullet, thinking this would fix the issue:

No real, luck yet though I haven't tried them all. Any pointers are appreciated!
